AbstractAbstract PDF
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.

AbstractAbstract PDF
BACKGROUND
Length of stay in ICU after thoracotomy is related to postoperative pulmonary function and complication which are affected by postoperative pain. For the post-thoracotomy pain control, epidural morphine is commonly used. Although total dose-requirement for analgesia of lumbar epidural morphine is more than the thoracic, lumbar epidural morphine could be substituted the thoracic. Our study compared the effect of patient controlled analgesia using thoracic epidural morphine (TEA group) and lumbar epidural analgesia with patient controlled intravenous analgesia using morphine (LEA+IV group).
METHODS
Sixty patients were randomly assigned into one of the two groups. The epidural taps were done before the induction. In all the patients morphine 0.2 mg/ml was administered via the epidural catheter at the end of surgery. In TEA group, basal infusion rate was 0.1 mg/hr and bolus dose was 0.02 mg. In LEA+IV group, basal infusion rate of epidural morphine was 0.1 mg/hr, patient controlled intravenous analgesia with morphine started when patients arrived at ICU, and basal infusion rate of intravenous morphine was 1.0 mg/hr and bolus dose was 0.8 mg. Pain score, side effect, postoperative length of stay in ICU and hospital were observed.
RESULTS
There were no significant differences between two groups in pain score, side effects, length of stay in ICU and hospital.
CONCLUSIONS
Lumbar epidural analgesia with patient controlled intravenous analgesia using morphine showed similar postoperative analgesia and length of stay in ICU and hospital compared to thoracic epidural analgesia with morphine, so that can substitute the thoracic epidural analgesia.

AbstractAbstract PDF
BACKGROUND
The purpose of this study was to evaluate the factors of cardiopulmonary resuscitation (CPR) outcome for in-hospital adult patients, acquiring data with standardized reporting guideline of in-hospital cardiopulmonary resuscitation in Korea.
METHODS
All adult cardiac arrest patients from July 2004 to December 2006 in this general hospital were included. Their clinical spectrums were reviewed retrospectively using Utstein-style based template.
RESULTS
For the study time period, one hundred and forty-two patients underwent cardiac arrest in this hospital. 136 patients were performed CPR. Return of spontaneous circulation (ROSC) occurred in 42 cases, and 15 patients were survived to hospital discharge. A shorter CPR time and a lower Simplified Acute Physiology Score II (SAPS II) were significant for survivor to hospital discharge (p<0.01). Sex, age, and location in cardiac arrest were not attributed to survival to hospital discharge.
CONCLUSIONS
In-hospital CPR patients, the high rate of ROSC and survival to hospital discharge were associated to the cause of arrest, shorter time of CPR, and lesser severity of disease (SAPS II). This result can be a great implication of survivor from CPR in-hospital adult patients in Korea. Further evaluation with consistent data acquisition of CPR using Utstein-style would contribute to improve CPR practice and outcome.

AbstractAbstract PDF
Extracorporeal membrane oxygenation (ECMO) is a life-sustaining salvage therapy applied to the patient with acute heart failure or respiratory failure which is considered curable, but uncorrectable by conventional means. Recently, accumulating data has shown the survival benefit of ECMO in patients with acute fatal cardiopulmonary decompensation. Here, we report a series of cases of successful ECMO treatment in patients with acute cardiopulmonary insufficiency. Case 1: A patient with progressive respiratory failure on mechanical ventilation after pneumonectomy was managed satisfactorily using a veno-venous ECMO. Case 2: A veno-arterial ECMO was used to support a patient with vasopressor refractory septic shock. After 5 days of treatment, the patient was successfully weaned from ECMO. Case 3: A patient in cardiac arrest after the orthopedic surgery was resuscitated using a veno-arterial ECMO. Pulmonary angiography on ECMO revealed massive pulmonary thromboembolism and embolectomy was thoroughly performed under the support of ECMO.

AbstractAbstract PDF
Intravenous immunoglobulin (IVIG) therapy has been introduced to idiopathic dilated cardiomyopathy due to their antiviral and anti-inflammatory effects. But each study reported conflicting result and treatment regimen has not been clearly established. We experienced a case of 28-year-old woman with idiopathic dilated cardiomyopathy with severely depressed cardiac function. Its onset time was obvious within 1 month. Despite of conservative treatment of heart failure, sudden cardiac arrest was developed. We tried IVIG therapy, and her symptoms and cardiac function were improved after IVIG treatment.

AbstractAbstract PDF
A 67-year old woman, hospitalized for the management of infectious colitis, developed acute congestive heart failure. Two-dimensional echocardiography revealed left ventricular apical akinesia (ballooning) and basal hyperkinesis, which was compatible with stress cardiomyopathy. A marked QT prolongation and T wave inversion followed by nonsustained polymorphic ventricular tachycardia was noted in the electrocardiogram. Intravenous administration of magnesium completely suppressed the ventricular tachycardia. After recovery from the colitis, the follow-up ECG and echocardiogram were normalized. There was no evidence of ischemic heart disease in the coronary angiography or perfusion scan. Takotsubo cardiomyopathy is one of the most important causes of acquired QT prolongation in ICU (intensive care unit) patients.. A careful monitoring of the QT interval in these patients is warranted particularly when drugs causing QT prolongation are used.
