Abstract
Purpose: The purpose of this study was to investigate the use of an AED by 119 rescuers in prehospital cardiac arrest.
Methods: 132 patients who experienced prehospital cardiac arrest and was defibrillated by 119 rescuers using AED from January 2003 to December 2004 were included in this study. They were reviewed retrospectively based on 119 rescue service records and ECG. We analyzed patients¡¯ general characteristics, types of ECG rhythm, time intervals from EMS activation to arrival and from EMS activation to the first defibrillation, numbers of defibrillation, and return of spontaneous circulation (ROSC).
Results: The mean age was 57.33¡¾17.84 years with 92 males and 40 females. 68 patients showed shockable rhythms (coarse ventricular fibrillation 41, fine ventricular fibrillation 24, pulseless ventricular tachycardia 3) and 39 patients showed unshockable rhythms (pulseless electrical activity 19 , asystole 18, normal sinus rhythm 2) as an initial rhythm at EMS arrival. Unshockable rhythms were changed to shockable rhythms after cardiopulmonary resuscitation. 25 patients had no ECG rhythms on 119 rescue service records. In the patients with shockable rhythms initially (68patients), 18 patients experienced ROSC, whereas only 1patients experienced ROSC in the patients with unshockable rhythms initially (39 patients). The patients with shockable rhythms initially had higher ROSC rates than the patients with unshockable rhythms initially (26.1% vs 2.6%,p=0.001) and received less defibrillation than the patients with unshockable rhythms initially (1.37¡¾0.60 vs 2.49¡¾ 1.87, p=0.016). There were no significant differences in the time intervals from EMS activation to arrival (5.74¡¾2.13 minutes vs 7.12¡¾4.33 minutes, p=0.529) and from EMS activation to the first defibrillation (14.20¡¾7.97 minutes vs
13.75¡¾7.30 minutes, p=0.542) between ROSC group & non-ROSC group. There was no significant difference in ROSC between male and female (13% vs 17.5%, p=0.164).
Conclusion: The patients with shockable rhythms initially had higher ROSC rates than the patients with unshockable rhythms initially (26.1% vs 2.6%, p=0.001) and receivedless defibrillation than the patients with unshockable rhythms initially (1.37¡¾0.60 vs 2.49¡¾1.87, p=0.016).
