Abstract
PDF - Background
This study investigated the characteristics of mechanically ventilated patients in South Korean intensive care units (ICUs). Methods: We conducted a subgroup analysis of a multinational observational study. Data from 271 mechanically ventilated patients in South Korean ICUs were analyzed for demographics, ventilation practices, and mortality, and were compared with those of 327 patients from other high-income Asian countries. Results: South Korean patients were older (mean age: 67 vs. 62 years, P<0.001) and had lower ratio of the partial pressure of arterial oxygen to the fraction of inspired oxygen (255.5 vs. 306.2, P<0.001). South Korean ICUs exhibited higher patient-to-nurse ratios (2.6 vs. 1.9, P<0.001) and more beds per unit (20.5 vs. 16.0, P=0.017). The use of sufficient positive end-expiratory pressure for patients (PEEP) for acute respiratory distress syndrome (ARDS) was less frequent in South Korea (62.2% vs. 91.2%, P=0.005). Mortality rates were similar between South Korean patients and those in other high-income Asian countries (38.0% vs. 34.2%, P=0.401). Significant mortality predictors in South Korea included age ≥65 years (odds ratio [OR], 4.03; P=0.039) and a Sequential Organ Failure Assessment score ≥8 (OR, 2.36; P=0.031). The presence of respiratory therapists was associated with reduced mortality (OR, 0.52; P=0.034). Conclusions: Despite higher age and patient-to-nurse ratios in South Korean ICUs, outcomes were comparable to those in other high-income Asian countries. The suboptimal use of sufficient PEEP with ARDS indicates potential areas for improvement. Additionally, the beneficial impact of respiratory therapists on mortality rates warrants further investigation.

Abstract
PDF
- Background
Legionella species are important causative organisms of severe pneumonia. However, data are limited on predictors of progression to severe Legionella pneumonia (LP). Therefore, the risk factors for LP progression from non-severe to the severe form were investigated in the present study.
Methods
This was a retrospective cohort study that included adult LP patients admitted to a 2,700-bed referral center between January 2005 and December 2019.
Results
A total of 155 patients were identified during the study period; 58 patients (37.4%) initially presented with severe pneumonia and 97 (62.6%) patients with non-severe pneumonia. Among the 97 patients, 28 (28.9%) developed severe pneumonia during hospitalization and 69 patients (71.1%) recovered without progression to severe pneumonia. Multivariate logistic regression analysis showed platelet count ≤150,000/mm3 (odds ratio [OR], 2.923; 95% confidence interval [CI], 1.100–8.105; P=0.034) and delayed antibiotic treatment >1 day (OR, 3.092; 95% CI, 1.167–8.727; P=0.026) were significant independent factors associated with progression to severe pneumonia.
Conclusions
A low platelet count and delayed antibiotic treatment were significantly associated with the progression of non-severe LP to severe LP. -

Abstract
PDF
Supplementary Material - Background
Korea is rapidly becoming a super aging society and is facing the increased burden of critical care for the elderly people. Traditionally, far-advanced age has been regarded as a triage criterion for intensive care unit (ICU) admission. We evaluated how the characteristics and prognostic factors of very elderly patients (≥85 years) admitted to the ICU changed over the last decade.
Methods
We retrospectively evaluated the data of patients admitted to the ICU over 11 years (2007–2017). The clinical characteristics and outcomes of the very elderly-patients group were evaluated. Factors associated with mortality were assessed by a cox regression analysis.
Results
Comparing the first half (2007–2012) and the second half (2013–2017) of the study period, the proportion of very elderly group increased from 603/47,657 (1.3%), to 697/37,756 (1.8%) (P<0.001). Among 1,294 very elderly patients, 1,274 patients were analyzed excluding hopeless discharge (n=20). The non-surgical reasons for ICU admission (67.0% vs. 76.1%, P<0.001) and the percentage of patients with co-morbidities (78.3% vs. 82.7%, P=0.048) were increased. Nevertheless, the hospital mortality decreased (21.3% vs. 14.9%, P=0.001). High creatinine levels, use of vasopressors and ventilator weaning failure were associated with in-hospital mortality.
Conclusions
The proportion of very elderly people in the ICU increased over the last decade. The non-surgical causes of ICU admission increased compared with the surgical causes. Despite an increasement in ICU admissions of very elderly patients, in-hospital mortality of very elderly ICU patients decreased. -

Abstract
PDFSupplementary Material
- Background
It is important for intensivists to determine which patient may benefit from intensive care unit (ICU) admission. We aimed to assess the outcomes of patients perceived as non-beneficially or beneficially admitted to the ICU and evaluate whether their prognosis was consistent with the intensivists’ perception.
Methods
A prospective observational study was conducted on patients admitted to the medical ICU of a tertiary referral center between February and April 2014. The perceptions of four intensivists at admission (day 1) and on day 3 were investigated as non-beneficial admission, beneficial admission, or indeterminate state.
Results
A total of 210 patients were enrolled. On days 1 and 3, 22 (10%) and 23 (11%) patients were judged as having non-beneficial admission; 166 (79%) and 159 (79%), beneficial admission; and 22 (10%) and 21 (10%), indeterminate state, respectively. The ICU mortality rates of each group were 64%, 22%, and 57%, respectively; their 6-month mortality rates were 100%, 46%, and 81%, respectively. The perceptions of non-beneficial admission or indeterminate state were the significant predictors of ICU mortality (day 3, odds ratio [OR], 4.049; 95% confidence interval [CI], 1.892–8.664; P<0.001) and 6-month mortality (day 1: OR, 4.983; 95% CI, 1.260–19.703; P=0.022; day 3: OR, 4.459; 95% CI, 1.162–17.121; P=0.029).
Conclusions
The outcomes of patients perceived as having non-beneficial admission were extremely poor. The intensivists’ perception was important in predicting patients’ outcomes and was more consistent with long-term prognosis than with immediate outcomes. The intensivists’ role can be reflected in limited ICU resource utilization. -

Abstract
PDF
- Background
Evidence for using high-flow nasal cannula (HFNC) in hypercapnia is still limited. Most of the clinical studies had been conducted retrospectively, and there had been conflicting reports for the effects of HFNC on hypercapnia correction in prospective studies. Therefore, more evidence is needed to understand the effect of the HFNC in hypercapnia.
Methods
We conducted a multicenter prospective observational study after applying HFNC to 45 hospitalized subjects who had moderate hypercapnia (arterial partial pressure of carbon dioxide [PaCO2], 43–70 mm Hg) without severe respiratory acidosis (pH <7.30). The primary outcome was a change in PaCO2 level in the first 24 hours of HFNC use. The secondary outcomes were changes in other parameters of arterial blood gas analysis, changes in respiration rates, and clinical outcomes.
Results
There was a significant decrease in PaCO2 in the first hour of HFNC application (-3.80 mm Hg; 95% confidence interval, -6.35 to -1.24; P<0.001). Reduction of PaCO2 was more prominent in subjects who did not have underlying obstructive lung disease. There was a correction in pH, but no significant changes in respiratory rate, bicarbonate, and arterial partial pressure of oxygen/fraction of inspired oxygen ratio. Mechanical ventilation was not required for 93.3% (42/45) of our study population.
Conclusions
We suggest that HFNC could be a safe alternative for oxygen delivery in hypercapnia patients who do not need immediate mechanical ventilation. With HFNC oxygenation, correction of hypercapnia could be expected, especially in patients who do not have obstructive lung diseases. -

Abstract
PDF
- Background
Although extracorporeal membrane oxygenation (ECMO) has been used for the treatment of acute high-risk pulmonary embolism (PE), there are limited reports which focus on this approach. Herein, we described our experience with ECMO in patients with acute high-risk PE.
Methods
We retrospectively reviewed medical records of patients diagnosed with acute highrisk PE and treated with ECMO between January 2014 and December 2018.
Results
Among 16 patients included, median age was 51 years (interquartile range [IQR], 38 to 71 years) and six (37.5%) were male. Cardiac arrest was occurred in 12 (75.0%) including two cases of out-of-hospital arrest. All patients underwent veno-arterial ECMO and median ECMO duration was 1.5 days (IQR, 0.0 to 4.5 days). Systemic thrombolysis and surgical embolectomy were performed in seven (43.8%) and nine (56.3%) patients, respectively including three patients (18.8%) received both treatments. Overall 30-day mortality rate was 43.8% (95% confidence interval, 23.1% to 66.8%) and 30-day mortality rates according to the treatment groups were ECMO alone (33.3%, n=3), ECMO with thrombolysis (50.0%, n=4) and ECMO with embolectomy (44.4%, n=9).
Conclusions
Despite the vigorous treatment efforts, patients with acute high-risk PE were related to substantial morbidity and mortality. We report our experience of ECMO as rescue therapy for refractory shock or cardiac arrest in patients with PE. -

Abstract
PDF
- Background
The 2016 Society of Critical Care Medicine (SCCM)/European Society of Intensive Care Medicine (ESICM) task force for Sepsis-3 devised new definitions for sepsis, sepsis with organ dysfunction and septic shock. Although Sepsis-3 was data-driven, evidence-based approach, East Asian descents comprised minor portions of the project population. Methods: We selected Korean participants from the fever and antipyretics in critically ill patients evaluation (FACE) study, a joint study between Korea and Japan. We calculated the concordance rates for sepsis diagnosis between Sepsis-2 and Sepsis-3 criteria and evaluated mortality rates of sepsis, sepsis with organ dysfunction, and septic shock by Sepsis-3 criteria using the selected data. Results: Korean participants of the FACE study were 913 (383 with sepsis and 530 without sepsis by Sepsis-2 criteria). The concordance rate for sepsis diagnosis between Sepsis-2 and Sepsis-3 criteria was 55.4%. The intensive care unit (ICU) and 28-day mortality rates of sepsis, sepsis with organ dysfunction, and septic shock patients according to Sepsis-3 criteria were 26.2% and 31.0%, 27.5% and 32.5%, and 40.8% and 43.4%, respectively. The quick Sequential Organ Failure Assessment (qSOFA) was inferior not only to SOFA but also to systemic inflammatory response syndrome (SIRS) for predicting ICU and 28-day mortality. Conclusions: The concordance rates for sepsis diagnosis between Sepsis-2 and Sepsis-3 criteria were low. Mortality rate for septic shock in Koreans was consistent with estimates made by the 2016 SCCM/ESICM task force. SOFA and SIRS were better than qSOFA for predicting ICU and 28-day mortality in Korean ICU patients. -

Abstract
PDF
- Chronic thromboembolic pulmonary hypertension is potentially curable with a pulmonary endarterectomy. However, approximately 20% of patients have persistent pulmonary hypertension after pulmonary endarterectomy, which is a major risk factor for postoperative death. Here, we report a 34-year-old woman who suffered persistent severe pulmonary hypertension following a successful pulmonary endarterectomy for chronic thromboembolic pulmonary hypertension. Extracorporeal membrane oxygenation (ECMO) and atrial septostomy were successfully performed as rescue treatments, and active rehabilitation during ECMO was prescribed to facilitate recovery.

Abstract
PDFSupplementary Material
- Background
Mesenchymal stem cells (MSCs) attenuate injury in various lung injury models through paracrine effects. We hypothesized that intratracheal transplantation of allogenic MSCs could attenuate lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice, mediated by anti-inflammatory responses.
Methods
Six-week-old male mice were randomized to either the control or the ALI group. ALI was induced by intratracheal LPS instillation. Four hours after LPS instillation, MSCs or phosphate-buffered saline was randomly intratracheally administered. Neutrophil count and protein concentration in bronchoalveolar lavage fluid (BALF); lung histology; levels of interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, and macrophage inflammatory protein-2; and the expression of proliferation cell nuclear antigen (PCNA), caspase-3, and caspase-9 were evaluated at 48 hours after injury.
Results
Treatment with MSCs attenuated lung injury in ALI mice by decreasing protein level and neutrophil recruitment into the BALF and improving the histologic change. MSCs also decreased the protein levels of proinflammatory cytokines including IL-1β, IL-6, and TNF-α, but had little effect on the protein expression of PCNA, caspase-3, and caspase-9.
Conclusions
Intratracheal injection of bone marrow-derived allogenic MSCs attenuates LPSinduced ALI via immunomodulatory effects. -

Abstract
PDF
- Background
The objective of this study was to investigate the characteristics and clinical outcomes of critically ill cancer patients admitted to intensive care units (ICUs) in Korea.
Methods
This was a retrospective cohort study that analyzed prospective collected data from the Validation of Simplified Acute Physiology Score 3 (SAPS3) in Korean ICU (VSKI) study, which is a nationwide, multicenter, and prospective study that considered 5,063 patients from 22 ICUs in Korea over a period of 7 months. Among them, patients older than 18 years of age who were diagnosed with solid or hematologic malignancies prior to admission to the ICU were included in the present study.
Results
During the study period, a total of 1,762 cancer patients were admitted to the ICUs and 833 of them were deemed eligible for analysis. Six hundred fifty-eight (79%) had solid tumors and 175 (21%) had hematologic malignancies, respectively. Respiratory problems (30.1%) was the most common reason leading to ICU admission. Patients with hematologic malignancies had higher Sequential Organ Failure Assessment (12 vs. 8, P<0.001) and SAPS3 (71 vs. 69, P<0.001) values and were more likely to be associated with chemotherapy, steroid therapy, and immunocompromised status versus patients with solid tumors. The use of inotropes/ vasopressors, mechanical ventilation, and/or continuous renal replacement therapy was more frequently required in hematologic malignancy patients. Mortality rates in the ICU (41.7% vs. 24.6%, P<0.001) and hospital (53.1% vs. 38.6%, P=0.002) were higher in hematologic malignancy patients than in solid tumor patients.
Conclusions
Cancer patients accounted for one-third of all patients admitted to the studied ICUs in Korea. Clinical characteristics were different according to the type of malignancy. Patients with hematologic malignancies had a worse prognosis than did patients with solid tumor. -

Abstract
PDF
- Background
High flow nasal cannula (HFNC) is known to increase global ventilation volume in healthy subjects. We sought to investigate the effect of HFNC on global and regional ventilation patterns in patients with hypoxia.
Methods
Patients were randomized to receive one of two oxygen therapies in sequence: nasal cannula (NC) followed by HFNC or HFNC followed by NC. Global and regional ventilation was assessed using electric impedance tomography.
Results
Twenty-four patients participated. Global tidal variation (TV) in the lung was higher during HFNC (NC, 2,241 ± 1,381 arbitrary units (AU); HFNC, 2,543 ± 1,534 AU; P < 0.001). Regional TVs for four iso-gravitational quadrants of the lung were also all higher during HFNC than NC. The coefficient of variation for the four quadrants of the lung was 0.90 ± 0.61 during NC and 0.77 ± 0.48 during HFNC (P = 0.035). Within the four gravitational layers of the lung, regional TVs were higher in the two middle layers during HFNC when compared to NC. Regional TV values in the most ventral and dorsal layers of the lung were not higher during HFNC compared with NC. The coefficient of variation for the four gravitational layers of the lung were 1.00 ± 0.57 during NC and 0.97 ± 0.42 during HFNC (P = 0.574).
Conclusions
In patients with hypoxia, ventilation of iso-gravitational regions of the lung during HFNC was higher and more homogenized compared with NC. However, ventilation of gravitational layers increased only in the middle layers. (Clinical trials registration number: NCT02943863). -

Abstract
PDF
- Background
Administering extracorporeal membrane oxygenation (ECMO) to critically ill patients with acute respiratory distress syndrome has substantially increased over the last decade, however administering ECMO to patients with hematologic malignancies may carry a particularly high risk. Here, we report the clinical outcomes of patients with hematologic malignancies and severe acute respiratory failure who were treated with ECMO.
Methods
We performed a retrospective review of the medical records of patients with hematologic malignancies and severe acute respiratory failure who were treated with ECMO at the medical intensive care unit of a tertiary referral hospital between March 2010 and April 2015.
Results
A total of 15 patients (9 men; median age 45 years) with hematologic malignancies and severe acute respiratory failure received ECMO therapy during the study period. The median values of the Acute Physiology and Chronic Health Evaluation II score, Murray Lung Injury Score, and Respiratory Extracorporeal Membrane Oxygenation Survival Prediction Score were 29, 3.3, and -2, respectively. Seven patients received venovenous ECMO, whereas 8 patients received venoarterial ECMO. The median ECMO duration was 2 days. Successful weaning of ECMO was achieved in 3 patients. Hemorrhage complications developed in 4 patients (1 pulmonary hemorrhage, 1 intracranial hemorrhage, and 2 cases of gastrointestinal bleeding). The longest period of patient survival was 59 days after ECMO initiation. No significant differences in survival were noted between venovenous and venoarterial ECMO groups (10.0 vs. 10.5 days; p = 0.56).
Conclusions
Patients with hematologic malignancies and severe acute respiratory failure demonstrate poor outcomes after ECMO treatment. Careful and appropriate selection of candidates for ECMO in these patients is necessary. -

Abstract
PDF
- Background
Many physicians hesitate to discuss do-not-resuscitate (DNR) orders with patients or family members in critical situations. In the intensive care unit (ICU), delayed DNR decisions could cause unintentional cardiopulmonary resuscitation, patient distress, and substantial cost. We investigated whether the timing of DNR designation affects patient outcome in the medical ICU.
Methods
We enrolled retrospective patients with written DNR orders in a medical ICU (13 bed) from June 1, 2014 to May 31, 2015. The patients were divided into two groups: early DNR patients for whom DNR orders were implemented within 48 h of ICU admission, and late DNR patients for whom DNR orders were implemented more than 48 h after ICU admission.
Results
Herein, 354 patients were admitted to the medical ICU and among them, 80 (22.6%) patients had requested DNR orders. Of these patients, 37 (46.3%) had designated DNR orders within 48 hours of ICU admission and 43 (53.7%) patients had designated DNR orders more than 48 hours after ICU admission. Compared with early DNR patients, late DNR patients tended to withhold or withdraw life-sustaining management (18.9% vs. 37.2%, p = 0.072). DNR consent forms were signed by family members instead of the patients. Septic shock was the most common cause of medical ICU admission in both the early and late DNR patients (54.1% vs. 37.2%, p = 0.131). There was no difference in in-hospital mortality (83.8% vs. 81.4%, p = 0.779). Late DNR patients had longer ICU stays than early DNR patients (7.4 ± 8.1 vs. 19.7 ± 19.2, p < 0.001).
Conclusions
Clinical outcomes are not influenced by the time of DNR designation in the medical ICU. The late DNR group is associated with a longer length of ICU stay and a tendency of withholding or withdrawing life-sustaining treatment. However, further studies are needed to clarify the guideline for end-of-life care in critically ill patients. -

Abstract
PDF
- Severe sepsis and septic shock are the main causes of death in critically ill patients. Early detection and appropriate treatment according to guidelines are crucial for achieving favorable outcomes. Endotoxin is considered to be a main element in the pathogenic induction of gram-negative bacterial sepsis. Polymyxin B hemoperfusion can remove endotoxin and is reported to improve clinical outcomes in patients with intra-abdominal septic shock, but its clinical efficacy for pneumonic septic shock remains unclear. Here, we report a case of a 51-year-old man with pneumonic septic shock caused by Pseudomonas aeruginosa, who recovered through polymyxin B hemoperfusion.

Abstract
PDF
- A 71-year-old male initially presented with vocal cord palsy and underwent tracheostomy. After thorough examination, urogenital dysfunction, orthostatic hypotension, and Parkinsonism were found, which led to the diagnosis of multiple system atrophy (MSA). After the tracheostomy, bi-level positive airway pressure ventilation was required during the night due to nocturnal hypoxemia. Nighttime hypoxemia is related to central sleep apnea, which is one of the manifestations of MSA. This is the first case of MSA manifested by bilateral vocal cord palsy as an initial sign in Korea. This case supports the notion that MSA should be taken into consideration when vocal cord paralysis is observed.

Abstract
PDF
- The goal of critical care is to reverse patients' acute problems in effective and ethical ways with minimum costs. Unlike in other medical fields, the quality of Korean critical care has lagged behind that of advanced countries. Moreover, the level of critical care quality differs significantly between university hospitals. The suboptimal critical care level has multifactorial causes. The major challenge to Korean intensivists is, therefore, how to overcome barriers in the current critical care delivery system to improve outcomes for critically ill patients and reduce medical errors in error-prone Intensive Care Unit (ICUs). A long-term task force including all stakeholders should address the multifactorial barriers to better outcomes. The Korean Society of Critical Care Medicine should perform the central role to dismantle the barriers step by step with a long-term vision for a desirable critical care delivery system in our society. A capable critical care team with full-time intensivists is the most urgent requirement for proper, timely care in ICUs. Intensivists should focus on basic but essential management so scarcity of resources can be minimized. Publicity about ICU to the general public is also urgently required to draw the attention of medical policy makers to the current suboptimal level of our critical care system.

Abstract
PDF
- Acute respiratory distress syndrome (ARDS) is a severe lung disease associated with high mortality despite recent advances in management. Significant advances in extracorporeal membrane oxygenation (ECMO) devices and management allow short-term support for patients with acute reversible respiratory failure and can serve as a bridge to transplantation in patients with irreversible respiratory failure. When ARDS does not respond to conventional treatment, ECMO and the interventional lung assist membrane (iLA) are the most widely used complementary treatment options. Here, we report a clinical case of an adult patient who required prolonged duration venovenous (VV)-ECMO for severe ARDS resulting in improvement while waiting for lung transplantation.

Abstract
PDF
- The use of extracorporeal membrane oxygenation (ECMO) has increased after the 2009 pandemic H1N1 infections, and the ECMO-related complications have also increased. Specifically, the mechanical vessel injury due to catheter cannulation seems to be less frequent than other complications, but there is a risk of hemorrhagic shock which requires special attention. We experienced a case of successful management with graft stenting during ECMO operation for iliac vein injury. A 56-year-old female patient with non-small cell lung cancer developed endobronchial obstruction, and ECMO was applied for the ECMO-assisted rigid bronchoscopy. During catheter cannulation, hypovolemic shock was developed due to her right external iliac vein injury. We detected the hemorrhage with bedside ultrasound at an early stage and the hemorrhage was effectively managed with graft stenting on ECMO.

Abstract
PDF
- Pumpless extracorporeal interventional lung assist (iLA) is a rescue therapy allowing effective carbon dioxide removals and lung protective ventilator settings. Herein, we report the use of a pumpless extracorporeal iLA in a tuberculosis destroyed lung (TDL) patient with severe hypercapnic respiratory failures. A 35-year-old male patient with TDL was intubated due to CO2 retention and altered mentality. After 11 days, Ventilator Associated Pneumonia (VAP) had developed. Despite the maximal mechanical ventilator support, his severe respiratory acidosis was not corrected. We applied the iLA for the management of refractory hypercapnia with respiratory acidosis. This case suggests that the iLA is an effective rescue therapy for TDL patients with ventilator refractory hypercapnia.

Abstract

- BACKGROUND
Rapid response team (RRT) is becoming an essential part of patient safety by the early recognition and management of patients on general hospital wards. In this study, we analyzed the usefulness of screening criteria of RRT used at Asan Medical Center.
METHODS
On a retrospective basis, we reviewed the records of 675 cases in 543 patients that were managed by RRT (called medical alert team in the Asan Medical Center), from July 2011 to December 2011. The medical alert team was acted by requests of attending doctors or nurses or the medical alert system (MAS) criteria composed of abnormal vital sign, neurology, laboratory data and increasing oxygen demand. We investigated the patterns of MAS criteria for targeting the patients who were managed by the medical alert team.
RESULTS
Respiratory distress (RR > 25/min) was the most common item for identifying patients whose condition had worsened. The criteria consist with respiratory distress and abnormal blood pressure (mean BP < 60 mmHg or systolic BP < 90 mmHg) found 70.0% of patients with deteriorated conditions. Vital sign (RR > 25/min, mean BP < 60 mmHg or systolic BP < 90 mmHg, pulse rate, PR > 130/min or < 50/min) and oxygen demand found 79.2% of them. Vital signs, arterial blood gas analysis (ABGA) with lactate level (pH, pO2, pCO2, and lactate) and O2 demand found 98.6% of patient conditions had worsened.
CONCLUSIONS
Vital signs, especially RR > 25/min is useful criteria for detecting patients whose conditions have deteriorated. The addition of ABGA data with lactate levels leads to a more powerful screening tool. -

Abstract
PDF
- BACKGROUND
Intracranial hemorrhage is a serious disease associated with high mortality and morbidity, and develops suddenly without warning. Although there were known risk factors, it is difficult to prevent brain hemorrhage from critically ill patients in the intensive care unit (ICU). There are several reports that brain hemorrhage, in critically ill patients, occurred in connection with respiratory diseases. The aim of our study is to describe the baseline characteristics and prognosis of patients with intracranial hemorrhage during mechanical ventilation in the ICU.
METHODS
We retrospectively reviewed the medical records of 56 patients, who developed intracranial hemorrhage in a medical ICU, from May 2008 to December 2011. During the mechanical ventilation in the ICU, patients were implemented with a weaning process, following ACCP (American College of Chest Physicians) criteria. Also, we compared patients with brain hemorrhage to those without brain hemorrhage.
RESULTS
Thirty two of the 56 patients (57.1%) were male, and median ages were 63 (17-90) years. The common type of brain hemorrhage confirmed was intracerebral hemorrhage/intraventricular hemorrhage (52.2%). The duration from mechanical ventilation to brain hemorrhage was 6 (0-58) days. Overall hospital mortality was 57.1%, and ICU mortality was 44.6%. The most common cause of death was brain hemorrhage (40.6%). In comparison to patients without brain hemorrhage, study patients showed less use of anticoagulants and lower ventilator pressure. Our study showed that the use of vasopressor, systolic blood pressure, peak airway pressure, and platelet count were associated with brain hemorrhage.
CONCLUSIONS
Intracranial hemorrhage showed high mortality in critically ill patients with mechanical ventilation. In the future, large case-control study will be needed to evaluate the risk factors of cerebral hemorrhage.

Abstract
PDF
- BACKGROUND
During 2009 pandemic period, many Koreans were infected and admitted with Influenza A/H1N1. The primary aim of this study was to evaluate whether the structures of an intensive care unit (ICU) were associated with the outcomes of critically ill patients.
METHODS
This retrospective observational study examined critically ill adult patients with influenza A/H1N1, who were admitted to 24 hospitals in Korea, from September 2009 to February 2010. We collected data of ICU structure, patients and 90 days mortality. Univariate and multivariate logistic regression analysis, with backward elimination, were performed to determine the most significant risk factors.
RESULTS
Of the 239 patients, mortality of 90 days was 43%. Acute physiology and chronic health evaluation (APACHE) II score (p < 0.001), sequential organ failure assessment (SOFA) score (p < 0.0001), nurse to beds ratio (p = 0.039) and presence of intensivist (p = 0.024) were significant risk factors of 90 days mortality. Age (p = 0.123), gender (p = 0.304), hospital size (p = 0.260), and ICU type (p = 0.409) were insignificantly associated with mortality. In a multivariate logistic regression analysis, patients with less than 6 SOFA score had significantly lower mortality, compared with those with more than 10 SOFA score (odds ratio 0.156, p < 0.0001). The presence of intensivist had significantly lower mortality, compared with the absence (odds ratio 0.496, p = 0.026).
CONCLUSIONS
In critically ill patients with influenza A/H1N1, the severity of the illness and presence of intensivist might be associated with 90 days mortality. -

Abstract
PDF
- Refractory asthma with hypercapnia is a near-fatal disease. Pumpless Extracorporeal Interventional Lung Assist (iLA) may be considered as an alternative therapy for the disease as it removes the carbon dioxide effectively. Nevertheless, clinical outcome studies regarding iLA in patients suffering from refractory asthma have rarely been applied. Here, we reported our experience with iLA for the treatment of refractory asthma with hypercapnia. In our case, the patient had refractory asthma which was not controlled with medical treatment or mechanical ventilation. We applied iLA since hypercapnia was not resolved despite mechanical ventilation. After iLA implantation effectively reduced the carbon dioxide, the clinical condition of our patient improved. In conclusion, iLA is a useful tool for patient suffering from refractory asthma with hypercapnia.

Abstract
PDF
- BACKGROUND
Initiation of renal replacement therapy (RRT) in critically ill septic shock patients with acute kidney injury is highly subjective and may influence outcome. The aim of this study is to evaluate the relationship between initiation of RRT and 28 day mortality in patients with severe sepsis and septic shock (SSSS).
METHODS
All patients diagnosed with SSSS and treated at the medical intensive care unit (ICU) in university-affiliated hospital from January 2005 to December 2006 were reviewed. Initiation of RRT was stratified into "early" and "late" by RIFLE (Risk, Injury, Failure, Loss, and End-stage) criteria and blood urea nitrogen (BUN) at the time RRT began. The primary outcome was death after 28 days from any cause.
RESULTS
Of the 326 patients diagnosed with SSSS and admitted into the medical ICU during the study period, 78 patients received RRT. Mean age was 61.5 +/- 14.7 years old and 54 patients were male (69.2%). The initiation of RRT was categorized into early (Risk, and Injury) and late (Failure) by RIFLE criteria and also categorized into early (BUN < 75 mg/dl) and late (BUN > or = 75 mg/dl). When the relationship between RIFLE criteria and 28 day mortality was compared, no significant difference was shown (70.8% vs. 73.3%, p = 0.81). The initiation of RRT by BUN also showed no significant difference in 28 day mortality (77.3% vs. 69.6%, p = 0.50).
CONCLUSIONS
Initiation of RRT, stratified into "early" and "late" by RIFLE and BUN, showed no significant difference in 28 day mortality regarding patient with SSSS.

Abstract
PDF
- BACKGROUND
In order to promote the dignity of terminal patients, and improve end-of-life care (EOL care) in Korea, consensus guidelines to the withdrawal of life-sustaining therapies (LST) were published in October, 2009. The aim of this study was to assess the current perception of the guideline among internal medicine residents and to identify barriers to the application of the guidelines.
METHODS
The study was designed prospectively on the basis of data from e-mail survey. We surveyed 98 medical residents working in 19 medical centers.
RESULTS
75.5% of respondents agreed with withdrawing (WD) of LST and 33.3% (33/98) of respondents were unaware of the guideline. Although 58.1% of all respondents had taken an EOL care class in medical school, about 30% of residents did feel uncomfortable with communicating with patients and surrogates. The most important obstacle for decision of WD of LST was the resident's psychological stress. 39.8% of medical residents felt guilty or failure after a patient's death, and 41.8% became often or always depressed in a patient's dying.
CONCLUSIONS
In order to protect and enhance the dignity and autonomy of terminal patients, the improvement of the medical training program in the hospitals and the more concern of educational leaders are urgent. -

Abstract

- BACKGROUND
A dramatic decrease in circulating lymphocyte number is observed after septic shock. In this study, we assessed whether circulating lymphocyte subpopulations influence the severity and prognosis of septic shock.
METHODS
133 patients (median 65 years, range 27-88; male 63.2%) receiving intensive care for septic shock were enrolled in this study. Flow cytometry phenotyping of circulating lymphocyte subpopulations, including helper T cells, suppressor T cells, total B cells, and natural killer (NK) cells, was performed within 24 hours after the diagnosis of septic shock. After measuring the white blood cell (WBC) and differential leukocyte count, the lymphocyte subsets were analyzed. The following data were recorded: general characteristics, severity of illness as assessed by the Sequential Organ Failure Assessment (SOFA) score, and 28-day mortality.
RESULTS
The overall mortality rate at 28 days was 33.8%. SOFA score was negatively correlated with the T cell count (r = -0.175) and helper T cell count (r = -0.223). However, only low a helper T cell count was associated with the severity of septic shock (odds ratio 0.995, 95% confidence interval 0.992-0.999, p = 0.014). Using multiple logistic regression analysis for 28-day mortality, there was no significant prognostic factor among the lymphocyte subset.
CONCLUSIONS
The low helper T cell count appeared to be associated with severity, but did not show significant association with mortality.

Abstract

- Pulmonary actinomycosis is an indolent and slowly progressive infectious disease, accompanied by pleural effusion and empyema in about 50% of cases. The size of the effusion is usually small, though, and it responds to appropriate antibiotics. We report a case of rapidly progressing, severe empyema leading to respiratory failure that was caused by pulmonary actinomycosis. A 57-year-old man presented with pleuritic chest pain for 5 days. The initial plain chest radiograph and CT scan showed pleural effusion. Gross pus was observed during the thoracentesis and laboratory test of pleural effusion revealed empyema. In spite of empirical antibiotics and chest tube drainage, the empyema rapidly progressed and the patient reached respiratory failure. Mechanical ventilation applied and decortication via video-assisted thoracotomy was performed. Microscopic examination of both the pleural and adjacent lung biopsy specimen revealed actinomycosis.

Abstract

- BACKGROUND
Pumpless interventional lung assist (iLA) uses an extracorporeal gas exchange system without any complex blood pumping technology, and has been shown to reduce CO2 tension and permit protective lung ventilation. The feasibility and safety of iLA were demonstrated in previous studies, but there has been no experience with iLA in Korea. The purpose of this study was to evaluate the feasibility of the iLA device in terms of physiologic efficacy and safety in Korean patients with acute respiratory failure.
METHODS
iLA was implemented in patients with acute respiratory failure who satisfied the predefined criteria of our study. Initiation of iLA followed an algorithm for implementation, ventilator care, and monitoring. Following insertion of arterial and venous cannulas under ultrasound guidance, the physiologic and respiratory variables and incidence of adverse events were monitored.
RESULTS
iLA was implemented in 5 patients and the duration of iLA ranged from 7 hours to 171 hours. At 24 hours after implementation, the mean changes in pH, PaCO2, and PaO2/FiO2 ranged from 7.204 to 7.393, from 68.4 mm Hg to 33 mm Hg, and from 128.7 mm Hg to 165 mm Hg, respectively. During iLA therapy, one adverse event was observed, which presented with hematochezia without hemodynamic change.
CONCLUSIONS
iLA treatment produced effective removal of carbon dioxide and allowed for protective ventilation in severe respiratory failure. An iLA system can easily be installed by percutaneous cannulation, without procedural complications, and without significant adverse events necessitating discontinuation of iLA after implementation. -

Abstract
PDF
- BACKGROUND
Despite the fact that a randomized controlled trial did not support the use of ketoconazole for treatment of acute lung injury (ALI), there is evidence that pretreatment with ketoconazole might prevent ALI in critically ill patients. An in vitro study showed, however, that itraconazole was a more potent inhibitor of thromboxane and leukotriene formation than was ketoconazole. We investigated the effect of itraconazole pretreatment in lipopolysaccharide (LPS)-induced ALI in rats.
METHODS
Twenty-one pathogen free, male Sprague-Dawley rats were administered either saline or LPS (5 mg/kg of body weight) intratracheally, with or without intraperitoneal pretreatment of itraconazole (2.5 mg/kg). Six hours after saline or LPS treatment (7 h after itraconazole pretreatment), samples were obtained.
RESULTS
Compared with the saline group, LPS group had increased total cell count, polymorphonuclear leukocyte differential count, protein, lactate dehydrogenase (LDH) and cytokines in BAL fluid. Itraconazole pretreatment decreased polymrphonuclear leukocyte differential count, protein and LDH in BAL fluid compared with those of LPS-treated rats without itraconazole pretreatment. Itraconazole pretreatment also decreased the elevated BAL fluid levels of interleukin-1beta (IL-1beta) and cytokine-induced neutrophil chemoattractant (CINC) by LPS. There was, however, no difference in the BAL fluid tumor necrosis factor alpha (TNF-alpha) level in terms of itraconazole pretreatment in LPS-treated rats. Histopathologic features of LPS-induced ALI were attenuated by itraconazole pretreatment.
CONCLUSIONS
These results suggest that itraconazole pretreatment attenuated LPS-induced ALI in rats. Decreases in levels of IL-1beta and CINC would likely be associated with attenuation of LPS-induced ALI in rats by itraconazole pretreatment. -

Abstract
PDF
- BACKGROUND
The initial management of acute critical patients is important. However, not all hospital facilities and staff are available during off-duty time. We determined the effects of intensive care unit (ICU) admission time on patient outcomes.
METHODS
This retrospective cohort study was conducted in a 28-bed medical ICU in 1 tertiary university hospital. Patients who were admitted between 1 March 2009 and 31 August 2009 were divided according to the time of admission into the "duty time group" (9 AM-5 PM on weekdays) and the "off-duty time group" (5 PM-9 AM on weekdays and at any time on weekends). The baseline characteristics and clinical outcomes were compared between these two groups. The primary endpoint of this study was hospital mortality; the secondary endpoints were ICU mortality and length of ICU stay, hospital length of stay, and mechanical ventilation time.
RESULTS
Two hundred eight (64.8%) of 321 enrolled patients were admitted during off-duty time. The baseline characteristics between the 2 groups were not significantly different. Hospital mortality was 37 (32.7%) in the "duty time group" and 82 (38.4%) in the "off-duty time group" (p = 0.237). There were no significant differences in secondary endpoints between the two groups.
CONCLUSIONS
Off-duty time admission to the ICU had no effect on hospital and ICU mortality, length of hospital and ICU stay, and mechanical ventilation time compared to duty time admission. -

Abstract
PDF
- BACKGROUND
The study focused on figuring out the present status and distribution of the underlying diseases of Korean terminally ill patients (TIP) who were on life-support care (LSC) by conducting a nationwide health care survey.
METHODS
The authors of this study requested that the 308 nationwide hospitals that operate intensive care units answer a questionnaire that asked about the number of admitted TIPs and their underlying diseases at 12 Am, 22 July, 2009. The proportion of TIPs among all the admitted patients and the percentages of the TIP's underlying diseases were calculated.
RESULTS
In a total of 83.1% of the eligible hospitals responded, the proportion of TIP was 1.6 of 100 admitted patients. Terminal cancer was the leading underlying disease in the TIPs (42.4%). Five % of the patients on LSC were brain dead. More TIPs were admitted in the national/public or university hospitals than in the private or non-university hospitals.
CONCLUSIONS
Futile treatment seems to be administered to the TIPs in Korean hospitals. The quality of terminal care in Korean hospitals should be improved by the application of socially acceptable LSC guidelines. Timely government health plans, including hospice care, to improve the quality of palliative care should be launched and maintained. -

Abstract
PDF
- BACKGROUND
To investigate the usage patterns of sedatives, analgesics and neuromuscular blocking agents (NMBAs) in patients requiring mechanical ventilation more than 72 hours in intensive care units (ICUs) of Korea.
METHODS
A total of 536 patients continuing mechanical ventilation more than 72 hours had been enrolled among the twenty-one ICUs of Korea from May 2003 to July 2003. Data about mechanical ventilation, the use of sedatives, analgesics, and NMBAs were prospectively collected for four weeks. We analyzed the patterns of using these drugs and effects on outcomes.
RESULTS
More than half of the patients (50.4%) received sedative drug alone. Most commonly used sedatives and analgesics were midazolam and morphine. NMBAs were administered in 41% of the patients. Volume controlled ventilation mode was associated with more frequent use of NMBAs. There were no significant differences in outcome variables among the usage patterns of sedatives, analgesics and NMBAs.
CONCLUSIONS
Our investigation shows that analgesics were much less frequently used in the intensive care units of Korea compared with the use of sedatives. And the use of NMBAs were quite a common. -

Abstract
PDF
- BACKGROUND
ASV is a closed-loop ventilation system that guarantees a user-set minimum per-minute volume in intubated patients, whether paralyzed or with spontaneous breathing. Here, we tested the effects of ASV onrespiratory mechanics and compared them with volume-controlled ventilation (VCV).
METHODS
Thirteen patients meeting the criteria for acute lung injury (ALI)/acute respiratory distress syndrome (ARDS) were enrolled. All patients were paralyzed to eliminate spontaneous breathing. We started with VCV (VCV1), then used ASV followed by VCV modes (VCV2), maintaining minute volume as much as that of VCV1.
RESULTS
During ASV, compared with VCV1, the inspiratory and expiratory tidal volumes and expiratory resistance increased. Conversely, the total respiratory rate and maximum pressure decreased. No changes in the arterial blood gases, heart rate, or mean systemic pressure were noted during the trial.
CONCLUSIONS
In ALI/ARDS patients, although no differences were observed in the arterial blood gas analysis between the two modes, ASV provided better respiratory mechanics in terms of peak airway pressure and tidal volume than VCV. -

Abstract
PDF
- BACKGROUND
Severe sepsis is a major cause of morbidity and mortality in intensive care units. This study aimed to evaluate the prevalence, characteristics, outcomes and prognostic factors of severe sepsis in a medical intensive care unit (MICU) of a tertiary care hospital in Korea.
METHODS
We retrospectively reviewed the medical chart of 249 patients who were admitted to a medical intensive care unit with severe sepsis.
RESULTS
From January 2000 to December 2001, 3410 patients were admitted to the ICU. The prevalence of severe sepsis was 7.3%. The mortality of severe sepsis was 64.6%. The prognostic factors for severe sepsis were the number of organ systems that acutely failed (p = 0.036) and an admission route from general wards (p = 0.018). There was no difference in the outcome of severe sepsis according to infectious organisms (p = 0.24) and the site of infections (p = 0.38).
CONCLUSIONS
Severe sepsis in the MICU is a common, expensive and often fatal condition. We expect that early rescucitation and recovery from acute organ system failure will improve the outcome of severe sepsis. -

Abstract
PDF
- BACKGROUND
Do-not-resuscitate (DNR) in the event of a cardiac arrest is the most common and important discussion between a patient's family and physicians among the end-of-life decision-making process. To observe the performance of a DNR order in critically ill patients, we analyzed the incidence of DNR orders, the changes in therapeutic levels after DNR orders, and the cases of violated DNR codes in patients who had died in a Korean medical intensive care unit (ICU) between 1 January 2006 and 30 June 2006.
METHODS
The charts of patients who had died in the medical ICU were retrospectively reviewed.
RESULTS
One hundred two patients were enrolled. The ICU and hospital lengths of stay of the patients were 12.4 +/- 14.0 and 23.2 +/- 21.1 days, respectively. Hematologic malignancy (24.5%) accounted for the most common premorbid diagnosis before ICU admission. Seventy-five patients (73.5%) had DNR orders. The DNR order was suggested by the physician in 96% of the patients. There was no significant difference in the clinical parameters and the performance of a DNR order. Eighty-four percent of the patients with a DNR order had received the order within 3 days death. The withholding of additional therapy or withdrawing of current therapy occurred in 57.3% of the patients. The DNR order was violated in 9 cases (12%).
CONCLUSIONS
DNR orders are well-accepted by the patient's family in the ICU. However, DNR orders are initiated when patient death is imminent. -

- BACKGROUND
Prone positioning has been adopted as a strategy to improve oxygenation in patients with refractory acute respiratory distress syndrome (ARDS). After returning to supine position, most of patients show arterial blood gas changes. However, the clinical implications have not been elucidated. This study was aimed to observe the relationship between the arterial blood gas changes followed by changing position from prone to supine and survival of ARDS.
METHODS
We analyzed medical data of 53 ARDS patients, who showed improved arterial oxygenation (defined as the increase in PaO2/FiO2 by > or =20 mmHg within 8~12 hour after prone positioning) in a medical intensive care unit from January, 2000 to July, 2006. The patients were returned to supine position when they showed their PaO2/FiO2 > or =150 mmHg. We compared the arterial blood gas changes between the survivor and the nonsurvivor.
RESULTS
The survivor has significant pH improvement after position change (the survivor 0.01+/-0.06 vs. the nonsurvivor -0.03+/-0.08; p=.03). The PaO2/FiO2 and FiO2 changes were not different between the survivor (14.44 +/-69.68 and -2.2+/-4.3, respectively) and the nonsurvivor (-7.17+/-83.94 and 1.8+/-6.0, respectively; p=.314 and .843). The patients whose PaO2/FiO2 were deteriorated had higher mortality without statistical significance (p=.305). The PaCO2 changes were not different between two groups (-0.05+/-11.46 vs. 3.47+/-17.62, p=.390).
CONCLUSIONS
The early changes in pH differed significantly between the survivor and the nonsurvivor after returning patients to supine position from prone. Whether this marker can be a predictor of survival should be studied further.

Abstract
PDF
- BACKGROUND
To evaluate effects of 5 expiratory sensitivity (ESENS) levels (5%; 15%; 25%; 35%; 45%) on lung mechanics and the effects depending on the two P(0.1) levels (<3 cm H2O; > or =3 cm H2O).
METHODS
Prospective, randomized, physiologic study for intubated adult patients during weaning from mechanical ventilation. Patients were randomly submitted to the 5 settings of ESENS in the Galileo ventilator (Galileo Gold, Hamilton Medical AG, Switzerland). Physiologic variables were continuously measured using a Bicore CP-100 pulmonary mechanics monitor (CP-100, Bicore, USA).
RESULTS
Thirteen patients, ten men and three women, with a mean age of 65.2+/-16.1 yr were studied. Tidal volume (V(T)) decreased significantly from ESENS 5% to 45%. With increasing levels of ESENS, respiratory rates (RR) steadily increased from ESENS 5% to 35% and 45%. Shallow breath index (F/V(T)) increased significantly from ESENS 5% to 45%. Inspiratory time (T(I)) decreased gradually significantly from ESENS 5% to 45%. RR and F/V(T) increased from ESENS 5% to 15% and 45% and V(T) decreased gradually in patients with P(0.1)<3 cm H2O group, but not in patients with P(0.1)> or =3 cm H2O.
CONCLUSIONS
The proper adjustment of expiratory sensitivity (ESENS) levels improved patient-ventilator synchrony and decreased respiratory rates and shallow breath index, especially in P(0.1)<3 cm H2O during PSV in ventilator weaning patients. Lower ESENS level would be more appropriate in terms of lung mechanics in patients with less than 3 cm H2O of P(0.1).

Abstract

- BACKGROUND
There are several METHODS: for auto-PEEP measurement during mechanical ventilation. The end-expiratory port occlusion (EEPO) method is simple and easy. Theoretically, auto- PEEP level can be also calculated by using trapped lung volume and static compliance. However, the relationship between measured auto-PEEP by EEPO method and the calculated auto-PEEP has not been studied. The purpose of this study is to observe the relationship between the measured and the calculated auto-PEEP. METHODS: 15 patients with auto-PEEP during mechanical ventilation were included. Auto-PEEP was measured by EEPO method, and calculated by using a formula; trapped lung volume/static compliance. All of the patients were paralyzed during the study. If the measured auto-PEEP is higher than calculated auto-PEEP, this patient was included in `high group'; in the opposite case, `low group'. We compared respiratory mechanics between these two groups. RESULTS: Measured auto-PEEP was 9.60+/-2.82 cmH2O, and calculated auto-PEEP was 9.78+/-2.90 cmH2O. There was statistically significant relationship between measured and calculated auto-PEEP (r=0.81, p<0.01). There was no difference on respiratory mechanics between `high group' and `low group'. CONCLUSIONS: The auto-PEEP obtained by calculation with trapped lung volume and static compliance showed a good correlation with that of using EEPO method in the paralyzed patients.

- BACKGROUND
A hospital ethics committee (HEC) handles ethics problems in a hospital and mediates conflicts between patients and caregivers. The role of HEC on treatment withdrawal has increased after Boramae-hospital's case on 1997 in Korea. This study is an analysis of cases referred to the HEC of Asan Medical Center for the discontinuation of patient therapy. METHODS: The conference records of the HEC from January 1998 to December 2003 and the relevant patient charts were reviewed retrospectively. RESULTS: Twenty-seven cases related to treatment withdrawal were referred to the HEC during the study period. Based on the number of admitted ICU patients during the study period, the case request rate was 0.05%. The bimodal distribution of the cases in terms of age was neonate, 13 (48%); infant, 6 (22%); adult, 8 (30%). The major causes of treatment withdrawal were futile management, financial difficulty and patient suffering. The HEC recommended the continuation of treatment in 7 cases (25.9%); treatment withdrawal in 11 (40.7%); treatment withholding in 8 (29.6%); transfer to another hospital in one case (3.8%). Of the seven recommendations for treatment continuation, only three were accepted by their families. These three patients were eventually discharged alive. Treatment was withdrawn within one week in all eleven cases recommended for that by the HEC. Treatment was withheld in seven of those eight such recommended cases. CONCLUSIONS: The case referral rate was low in the studied hospital. In all cases, the patients' families requested the case to the HEC. Although the committee's recommendations to withhold or withdraw the treatment were followed by the families, the recommendation to continue therapy was often refused.

- BACKGROUND
Critical illness polyneuropathy (CIP) is a primary distal axonal degeneration of motor and sensory fibers leading to severe limb weakness and difficulty in weaning from ventilator in critically ill patients. The object of this study is to evaluate the clinical findings of CIP and the risk factors associated with CIP development in patients with mechanical ventilator treatment. METHODS: We examined 40 patients, between March 2002 to February 2003, who manifested muscular weakness and received mechanical ventilation (MV) more than three days, prospectively. Nerve conduction velocity (NCV) and electromyography (EMG) were performed in all patients in the ICU. We examined the use of drugs (neuromuscular blocking agents, corticosteroid, and aminoglycoside), duration of MV and weaning, and APACHE II score. RESULTS: We observed 40 patients who showed muscular weakness, 9 patients were diagnosed as CIP. NCV study demonstrated decreased action potential amplitude, predominantly in motor nerve, distal part. There was no significant difference in duration of MV and weaning, drug use, APACHE II score between the groups with CIP and without CIP. CONCLUSIONS: CIP is an important neuromuscular complication of the patients in ICU. We should consider the possibility of the development of CIP in patients who showed muscular weakness and difficult weaning in critically ill patients.

- Congenital cystic adenomatoid malformation (CCAM) is a rare congenital disorder of pulmonary development that usually presenting as a respiratory distress in the neonatal period. Presentation in adulthood is rare and only 40 cases of CCAM in adulthood have been reported in literatures. A 49-year-old woman presented with hemoptysis. Postero anterior chest radiograph showed an air-fluid level in right upper lobe. A computed tomographic (CT) scan of the chest showed multilocular thick-walled cystic lesions in right upper lobe. A CT angiography showed cystic lesions with normal bronchial artery supply in right upper lobe, which were consistent with CCAM. A complete surgical resection of the right upper lobe was performed confirming a type 2 CCAM according to the expanded Stocker's classification.

Abstract
PDF
- Because inhaled nitric oxide (NO) induces selective vasodilation of well-ventilated lung regions diverting pulmonary artery blood flow towards these well-ventilated alveoli, it has been applied to some of ARDS patients, who show severe hypoxemia despite of positive pressure ventilation with moderate to high positive end-expiratory pressure. The beneficial effect of inhaled NO on oxygenation was lower than 5 ppm of inhaled NO and the maximum effect was about 10 ppm in patients with ARDS according to the studies. Combinations of inhaled NO with various therapies, such as the use of intravenous almitrine or phenylephrine, and prone positioning may produce additive effects on oxygenation. Approximately 65% of patients had response to inhaled NO in studies of critically ill patients with ARDS who were ventilated with less than 40 ppm of inhaled NO. However, there was no survival benefit by inhaled NO in a multicenter phase 2 trial with 177 patients of non-septic ARDS. It is unclear whether inhaled NO exerts detrimental or beneficial effects in the pathogenesis of ARDS. Laboratory studies suggest that inhaled NO has important effects in reducing some forms of lung and tissue injury. If these effects are clinically significant, early and continued therapy with inhaled NO could potentially reduce the severity of some forms of lung injury. In contrast, NO and nitrite interacted with neutrophil myeloperoxidase to stimulate oxidative reactions during inflammation. In summary, NO inhalation would be acceptable as a rescue therapy in severe ARDS without serious complications related to the application. In addition, the effect of inhaled NO on the pathophysiology of ARDS should be elucidated.

Abstract
PDF
- BACKGROUND
Norepinephrine, which is frequently administered as a vasopressor to the patients with septic shock, can decrease splanchnic and renal blood flows and aggravate splanchnic and renal ischemia. The low-dose dopamine (LDD) has been frequently combined with norepinephrine to ameliorate renal and splanchnic hypoperfusion in patients with septic shock. However, the effect of the LDD on the splanchnic and renal blood flow has not been fully elucidated. This investigation was carried out to determine the effect of the LDD on the splanchnic and renal blood flow in the patients with septic shock under the treatment of norepinephrine.
METHODS
Eleven patients with septic shock were included in this study. All of them were under the norepinephrine treatment as the mean arterial pressure (MAP) was less than 70 mm Hg in spite of the adequate fluid resuscitation. With stabilization of MAP, the LDD (2 g/kg/min) was administered for two hours in each patients. Hemodynamics, gastric intramucosal pH (pHi), gastric regional PCO2 (rPCO2), rPCO2 - PaCO2, urine volume, urine sodium excretion and creatinine clearance were compared between with and without the LDD infusion. Diuretics was not used during the study period.
RESULTS
Age of patients (n=11) was 64 12 and the APACHE III score was 84 17. The mortality rate of the subjects was 64%. Dosage of norepinephrine was 0.55 0.63 g/kg/min during the study period. There were no significant differences in hemodynamics (central venous pressure, cardiac output, pulmonary artery occlusion pressure, mixed venous gas), pHi, rPCO2, rPCO2 - PaCO2 depending on the concomitant infusion of the LDD. The volume of urine tended to increase (P=0.074) after concomitant LDD, but the changes in urine sodium excretion and creatinine clearance were not significantly different.
CONCLUSIONS
The combined infusion of the LDD with norepinephrine did not improve splanchnic and renal blood flow in the patients with septic shock.

- BACKGROUND
While the combination therapy of morphine and benzodiazepine has been recommended as a standard therapy for sedation and analgesia in patients with mechanical ventilation, morphine can suppress respiratory center, and also decrease blood pressure and bowel movement. Because ketamine has analgesic and sedative effects compatible to morphine without depression of the cardiovascular and respiratory systems in addition to the preservation of bowel activity, ketamine may substitute morphine. However, it has not well known such potential advantages of ketamine in patients with mechanical ventilation.
METHODS
Thirty eight patients (male:female=30:8, age=62.6 +/- 11.7 years) with mechanical ventilation were randomized as ketamine and morphine group (n=21 vs. n=17). There was no significant differences in sex, age and APACHE III score at the initiation of mechanical ventilation (ketamine group, morphine group: 79.4 +/- 2.0, 82.0 +/- 20.6). The study duration was 24 h after drug administration and minimum dose, which maintains ventilator-patient synchrony or the status of Ramsay score 3, was used. Ramsay sedation score, hemodynamic variables, respiratory and arterial blood gas variables, and bowel sound were measured at every 4 h. Arterial blood gas analysis was checked at 0, 4, and 24 h.
RESULTS
1) There were no significant differences in Ramsay sedation score and other hemodynamic, respiratory, and arterial blood gas variables in each group. The dose of combined midazolam was not different between two groups (ketamine vs. morphine; 52.1 +/- 11.9 vs. 46.7 +/- 15.1 mg/d; p=0.23). 2) The cases with decreased mean arterial pressure over 25% of the baseline shortly after the drug administration less frequently observed in ketamine group, although the difference did not reach statistical significance (n=2, 9.5% vs. n=5, 29.4%; p=0.12). 3) Bowel movement reduction at 4 h after the drug administration was less in ketamine group (n=1, 4.8% vs. n=6, 35.3%, p=0.03). The difference was not observed at 8 h. 4) Cost of the drug for 24 h was more expensive in ketamine group (dose & cost; 688 506 mg/d & 25,891 7,743 won vs. 40 +/- 18 mg/d, 15,814 +/- 4,853 won; p<0.001).
CONCLUSIONS
Considering the advantages in the hemodynamics and bowel movement, ketamine may substitute morphine for the sedation of patients with mechanical ventilation, if indicated.
