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
BACKGROUND
To evaluate the feasibility of noninvasive hemodynamic monitoring (impedance cardiography, ICG) in critically ill patients, we compared this technique with simultaneous invasive monitoring with a pulmonary artery thermodilution catheter.
METHODS
A prospective observational study was done comparing invasive monitoring and noninvasive monitoring in 12 critically ill patients. The cardiac output (CO), the stroke volume (SV) and the systemic vascular resistance (SVR) measured by using a standard thermodilution pulmonary artery catheter technique were compared with the corresponding measurements simultaneously using an ICG.
RESULTS
The value of CO, SV and SVR measured by ICG were closely correlated to those by the thermodilution methods [r: 0.659 (p<0.01), 0.536 (p<0.01), 0.738 (p<0.01)].
CONCLUSIONS
ICG can provide hemodynamic information previously available only by invasive monitoring with a thermodilution catheter.
