- BACKGROUND
Hyperglycemia is a common disease in critically ill patients, even those without diabetes. It has been recognized acute increase of blood glucose level would increase mortality in patients with and without diabetes in vascular disease such as acute myocardial infarct or acute stroke. However, there is not much data about hyperglycemic effects on the prognosis of patients with heterogenous disease in general intensive care unit (ICU). Aim of this study was to evaluate the effects of admission hyperglycemia on prognosis of critically ill patients with heterogenous disease. METHODS: We reviewed medical records of 712 patients admitted general ICU from July, 2000 to March, 2002 in teaching hospital. The patients who were not checked blood glucose level at ICU admission were excluded. We regarded diabetes patients who have been diagnosed diabetes before ICU admission. Hyperglycemia was defined as a fasting glucose level above 140 mg/dl or random glucose level above 200 mg/dl on 2 or more determinations. We measured hospital mortality, ICU stay, and hospital stay as well as blood glucose level. RESULT: Patients mortalities of diabetic hypergylcemia, nondiabetic hyperglycemia, diabetic normoglycemia, and nondiabetic normoglycemia were 17%, 19%, 26% and 10% respectively. CONCLUSIONS: Mortality of diabetic patients regardless of hyperglycemia at admission time and nondiabetic hyperglycemia patients were higher than nondiabetic normoglycemia patients in ICU.

- BACKGROUND
Patients readmitted to intensive care unit (ICU) have significantly higher mortality. The role of intensivists to judge when to discharge from ICU may be important. We performed this study to assess the effect of intensivist's discharge decision-making on readmission to ICU. METHODS: Data were collected prospectively from patients admitted to ICUs (group 1). Another data were collected retrospectively from the patients' record (group 2). Discharge of the patients in group 1 were based on intensivist's discharge decision-making but not in group 2.
We encouraged deep breathing and expectoration to patients of group 1 at risk of pulmonary complication during ICU stay and used a guideline for making discharge decisions.
Readmission cause, length of ICU stay, Acute Physiology and Chronic Health Evaluation (APACHE) III score, and multiple organ dysfunction syndrome (MODS) score of readmitted patients were evaluated. RESULTS: Readmission rate of group 1 was lower than that of group 2 (p<0.05). The mortality of readmitted patients in each group was higher than that of non-readmitted patients (p<0.05). Respiratory disease was the major cause of readmission. In non-survivors of readmitted patients, APACHE III score on initial discharge and readmission, MODS score on initial admission, discharge and readmission were higher than those of survivors (p<0.05). CONCLUSIONS: Readmission rate was lower when intensivists participated in discharge decision- making. ICU readmission was associated with higher hospital mortality and longer ICU stay. MODS and APACHE III score at first discharge and readmission were significant prognostic factors of the outcome in readmitted patients.

- Cervical spinal cord injury results in significant dysfunction of the sympathetic nervous system. Reduced sympathetic activity below the level of spinal cord injury is associated with low resting blood pressure,orthostatic hypotension,and reflex bradycardia.Hypotension can be treated with vasoactive agents,such as dopamine,epinephrine,norepinephrine, and phenylephine .Orally administered midodrine is an alpha adrenergic receptor agonist that increases blood pressure with vasoconstriction.Its action is fast and effective in treating hypotension in patients with spinal cord injury,and it has less severe side effects.A 70-year-old tetraplegic patient with fracture and dislocation of C6-7 after a motor vehicle accident was admitted to ICU and underwent anterior cervical intervertebral body fusion.Symptomatic hypotension following postural changes was treated with intravenous infusion of dopamine,but it was difficult to reduce the dose of dopamine without causing severe hypotension.Midodrine was prescribed and the patient was well tolerated without any adverse effect.With adequately maintained blood pressure,intravenous infusion of dopamine was successfully switched to the oral midodrine.This case suggests that the midodrine is effective for the treatment of hypotension in tetraplegic patients with spinal cord injury and enables patients to participate in early rehabilitation therapies.

Abstract

- Phrenic nerve palsy is a well-known complication following cardiac surgery in children. The incidence is approximately 1~2%. In infants and young children, it often causes a life-threatening respiratory distress. They must be treated with mechanical ventilation in the ICU. Many patients with phrenic nerve injury who is impossible to wean from a ventilator are candidates of diaphragmatic plication.
Diaphragmatic plication is performed to restore the normal pulmonary parenchymal volume by replacing the diaphragm to its proper location. This is a case of 2-months-old infant who had phrenic nerve palsy after the removal of cavernous lymphangioma of the chest. He underwent 4 operations to remove the mass and to have pericardiotomy. We tried to wean him from the ventilator but failed several times in the ICU.
After 4th operation, right diaphragmatic elevation was noted from the chest X ray. Phrenic nerve palsy was confirmed with fluoroscopy and he underwent diaphragmatic plication on 42 days after his 4th operation. Three days after the diaphragmatic plication, weaning was successfully carried out.

- The increase in short-term survival of near-drowning victims after an acute submersion episode has resulted in an increase of major complications. Two major complications are the development of acute respiratory distress syndrome and persistent hypoxic-ischemic central nervous system injury. A 43-year-old male patient was presented with acute respiratory distress syndrome after near drowning. He was severely hypothermic and hypotensive when he arrived to emergency department. His body temperature was 24oC. There was no pulse and no spontaneous respiration. He was treated with advanced life support measure. He was intubated and vasoactive drugs such as epinephrine and norepinephrine were used. On ICU admission, his blood pressure and pulse rate were 80/40 mmHg, 170 beats/min respectively. His oxygen saturation was 40~60% with 100% oxygen. We applied 16~30 cmH2O of PEEP with low tidal volume for recruitment. Patient was flipped over to prone position. Solu-medrol 1.0 g was infused. The blood pressure restored to 140/50 mmHg, and the pulse rate was normalized to 100 beats/min. The dose of vasopressors and inotropes were reduced and stopped 5 hour after the arrival. When the oxygenation has improved, the position was changed to supine and PEEP was lowered.
Eventually weaning was successful. Brain MRI and EEG showed global atrophy of cerebral cortex and moderate diffuse brain dysfunction respectively. He received tracheostomy since he was semi-comatose. He was transferred to general ward on 39th ICU day.
