In mechanically ventilated patients, assisted mechanical ventilation (MV) is employed early, following the acute phase of critical illness, in order to eliminate the detrimental effects of controlled MV, most notably the development of ventilator-induced diaphragmatic dysfunction. Nevertheless, the benefits of assisted MV are often counteracted by the development of patient-ventilator dyssynchrony. Patient-ventilator dyssynchrony occurs when either the initiation and/or termination of mechanical breath is not in time agreement with the initiation and termination of neural inspiration, respectively, or if the magnitude of mechanical assist does not respond to the patient’s respiratory demand. As patient-ventilator dyssynchrony has been associated with several adverse effects and can adversely influence patient outcome, every effort should be made to recognize and correct this occurrence at bedside. To detect patient-ventilator dyssynchronies, the physician should assess patient comfort and carefully inspect the pressure- and flow-time waveforms, available on the ventilator screen of all modern ventilators. Modern ventilators offer several modifiable settings to improve patient-ventilator interaction. New proportional modes of ventilation are also very helpful in improving patient-ventilator interaction.

Abstract PDF

Background
Pulmonary complications including pneumonia and pulmonary edema frequently develop in critically ill surgical patients. Lung ultrasound (LUS) is increasingly used as a powerful diagnostic tool for pulmonary complications. The purpose of this study was to report how LUS is used in a surgical intensive care unit (ICU).
Methods
This study retrospectively reviewed the medical records of 67 patients who underwent LUS in surgical ICU between May 2016 and December 2016.
Results
The indication for LUS included hypoxemia (n = 44, 65.7%), abnormal chest radiographs without hypoxemia (n = 17, 25.4%), fever without both hypoxemia and abnormal chest radiographs (n = 4, 6.0%), and difficult weaning (n = 2, 3.0%). Among 67 patients, 55 patients were diagnosed with pulmonary edema (n = 27, 41.8%), pneumonia (n = 20, 29.9%), diffuse interstitial pattern with anterior consolidation (n = 6, 10.9%), pneumothorax with effusion (n = 1, 1.5%), and diaphragm dysfunction (n = 1, 1.5%), respectively, via LUS. LUS results did not indicate lung complications for 12 patients. Based on the location of space opacification on the chest radiographs, among 45 patients with bilateral abnormality and normal findings, three (6.7%) and two (4.4%) patients were finally diagnosed with pneumonia and atelectasis, respectively. Furthermore, among 34 patients with unilateral abnormality and normal findings, two patients (5.9%) were finally diagnosed with pulmonary edema. There were 27 patients who were initially diagnosed with pulmonary edema via LUS. This diagnosis was later confirmed by other tests. There were 20 patients who were initially diagnosed with pneumonia via LUS. Among them, 16 and 4 patients were finally diagnosed with pneumonia and atelectasis, respectively.
Conclusions
LUS is useful to detect pulmonary complications including pulmonary edema and pneumonia in surgically ill patients.

Abstract PDF

Background
Severe or massive postpartum hemorrhage (PPH) has remained a leading cause of maternal mortality for decades across the world and it results in critical obstetric complications. Recombinant activated factor VII (rFVIIa) has emerged as a gold standard adjunctive hemostatic agent for the treatment of life-threatening PPH refractory to conventional therapies although it remains off-licensed for use in PPH. We studied the effects of rFVIIa on coagulopathy, transfusion volume, prognosis, severity change in Korean PPH patients.
Methods
A retrospective review of medical records between December 2008 and March 2011 indicating use of rFVIIa in severe PPH was performed. We compared age, rFVIIa treatment, transfusion volume, and Sequential Organ Failure Assessment (SOFA) score at the time of arrival in the emergency department and after 24 hours for patients whose SOFA score was 8 points or higher.
Results
Fifteen women with SOFA score of 8 and above participated in this study and eight received rFVIIa administration whereas seven did not. Patients’ mean age was 31.7 ± 7.5 years. There was no statistically significant difference in initial and post-24 hours SOFA scores between patients administered rFVIIa or not. The change in SOFA score between initial presentation and after 24 hours was significantly reduced after rFVIIa administration (P = 0.016).
Conclusions
This analysis aimed to support that the administration of rFVIIa can reduce the severity of life-threatening PPH in patients. A rapid decision regarding the administration of rFVIIa is needed for a more favorable outcome in severe PPH patients for whom there is no effective standard treatment.

Abstract PDF

Background
The Acute Physiology and Chronic Health Evaluation (APACHE) II scoring system and the Sequential Organ Failure Assessment (SOFA) scoring system are widely used for critically ill patients. We evaluated whether APACHE II score and SOFA score predict the outcome for trauma patients in the intensive care unit (ICU).
Methods
We retrospectively analyzed trauma patients admitted to the ICU in a single trauma center between January 2014 and December 2015. The APACHE II score was figured out based on the data acquired from the first 24 hours of admission; the SOFA score was evaluated based on the first 3 days in the ICU. A total of 241 patients were available for analysis. Injury Severity score, APACHE II score, and SOFA score were evaluated.
Results
The overall survival rate was 83.4%. The non-survival group had a significantly high APACHE II score (24.1 ± 8.1 vs. 12.3 ± 7.2, P < 0.001) and SOFA score (7.7 ± 1.7 vs. 4.3 ± 1.9, P < 0.001) at admission. SOFA score had the highest areas under the curve (0.904). During the first 3 days, SOFA score remained high in the non-survival group. In the non-survival group, cardiovascular system, neurological system, renal system, and coagulation system scores were significantly higher.
Conclusions
In ICU trauma patients, both SOFA and APACHE II scores were good predictors of outcome, with the SOFA score being the most effective. In trauma ICU patients, the trauma scoring system should be complemented, recognizing that multi-organ failure is an important factor for mortality.

Background
Serum albumin as an indicator of the disease severity and mortality is suggested in adult patients, but its role in pediatric patients has not been established. The objectives of this study are to investigate the albumin level as a biomarker of poor prognosis and to compare it with other mortality predictive indices in children in intensive care unit (ICU).
Methods
Medical records of 431 children admitted to the ICU at Severance Hospital from January 1, 2012 to December 31, 2015 were retrospectively analyzed. Children who expired within 24 hours after ICU admission, children with hepatic or renal failure, and those who received albumin replacement before ICU admission were excluded.
Results
The children with hypoalbuminemia had higher 28-day mortality rate (24.60% vs. 9.28%, P < 0.001), Pediatric Index of Mortality (PIM) 3 score (9.23 vs. 8.36, P < 0.001), Pediatric Risk of Mortality (PRISM) III score (7.0 vs. 5.0, P < 0.001), incidence of septic shock (12% vs. 3%, P < 0.001), C-reactive protein (33.0 mg/L vs. 5.8 mg/L, P < 0.001), delta neutrophil index (2.0% vs. 0.6%, P < 0.001), lactate level (1.6 mmol/L vs. 1.2 mmol/L, P < 0.001) and lower platelet level (206,000/μl vs. 341,000/μl, P < 0.001) compared to the children with normal albumin level. PIM 3 (r = 0.219, P < 0.001) and PRISM III (r = 0.375, P < 0.001) were negatively correlated with serum albumin level, respectively.
Conclusions
Our results highlight that hypoalbuminemia can be a biomarker of poor prognosis including mortality in the children in ICU.

Abstract PDF

A 70-year-old woman with Parkinson disease was admitted to the emergency department with altered consciousness, fever and convulsive movements without experiencing withdrawal from antiparkinsonian medication. Six hours after the emergency department visit, the patient had a hyperpyrexia (>40°C) and a systolic blood pressure of 40 mmHg. There was no evidence of bacterial infection based on extensive workups. The patient was discharged without aggravation of Parkinson disease symptoms after treatment that included administration of dantrolene sodium, enforcement of continuous renal replacement therapy and cooling blankets. Malignant syndrome should be suspected if high fever occurs in Parkinson disease patients without evidence of a definitive infection.

Abstract PDF

Although methidathion is an organophosphate insecticide, it is different from the other organophosphates in terms of toxicity. Because of its relatively high fat solubility, the apparent volume of methidathion distribution throughout the body is very high, indicating that hemoperfusion is not effective in removing this organophosphate from the body. Redistribution of methidathion from fat to blood can also occur when plasma levels diminish. Additionally, acetylcholinesterase aging, which is the loss of an alkyl side chain that prevents reactivation by oximes, is very rapid so that the effective reactivation by oximes is thwarted. Thus, methidathion’s effect on acetylcholinesterase inhibition is long lasting, particularly with a high dose. In addition to its parasympatholytic effect and ability to induce muscle paralysis, methidathion poisoning is associated with a profound and long-lasting circulatory collapse due to sympathetic ganglion blockade. This report presents the case of a 55-year-old man who accidentally ingested a high dose of methidathion. He later developed enteroinvasive aspergillosis infection-induced multiple bowel perforations on two separate occasions while on mechanical ventilator support, resulting in a fatal outcome. The renin-angiotensin axis activated by sympathetic ganglion blockade may have reduced the patient’s splanchnic blood flow, contributing to translocation of endotoxin. Also, the effect of excessive acetylcholine on non-neuronal acetylcholine receptors may have contributed to the development of fatal enteroinvasive aspergillosis in this patient.
