Abstract
Patients and methods We performed a prospective, observational study of nonconsecutive, non-trauma, adult, out of hospital cardiac arrest (OHCA) patients. This study conducted in emergency department of single tertiary university hospital. Echo performed every 2 minute simultaneously with pulse check within 10 second throughout the arrest, which was managed by the usual advanced cardiac life-support treatment guidelines. We obtained sub-xiphoid or parasternal long axis view of echo. We defined echocardiographic evidence of cardiac kinetic activity as any detected motion of the myocardium, ranging from visible ventricular fibrillation to coordinated ventricular contractions.
Highlights
There are many studies about predictive factor of return of spontaneous circulation (ROSC) during the cardiopulmonary resuscitation (CPR), but no definite guideline or predictive factor for termination of CPR
The purpose of this study is to figure out the relationship between ROSC and cardiac activity findings by echocardiography(echo) in cardiac arrest patients, and investigate the cardiac standstill period can be used as indicator for termination resuscitation
Interval from EMS call to EMS scene arrival is 8±3 minutes, Interval from EMS call to EMS hospital arrival is 23±6 minutes. 17 (51.5%) patients attained ROSC, and 1 (3%) patient discharged in cerebral performance category 1
Summary
The purpose of this study is to figure out the relationship between ROSC and cardiac activity findings by echocardiography(echo) in cardiac arrest patients, and investigate the cardiac standstill period can be used as indicator for termination resuscitation. Interval from EMS call to EMS scene arrival is 8±3 minutes, Interval from EMS call to EMS hospital arrival is 23±6 minutes. 17 (51.5%) patients attained ROSC, and 1 (3%) patient discharged in cerebral performance category 1. Repetitive cardiac standstill periods in ROSC group and no ROSC group were 2.9±2.4 minutes versus 18.9±8.4 minutes, respectively (p
