Abstract

Two hundred sixty patients in cardiac arrest were treated with an automatic external defibrillator by first-responding firefighters before arrival of paramedics. On average, first responders arrived 5 minutes before paramedics. Of 118 patients with ventricular fibrillation, 91 (77%) were administered shocks, 21 (23%) of whom had return of pulse and blood pressure by the time paramedics arrived. Fifty-six (62%) were admitted to the hospital and 30 (33%) survived. The survival rate for all 118 victims discovered with ventricular fibrillation was 27%. The device correctly classified the initial and all subsequent rhythms in 92 patients with asystole, 46 with electromechanical dissociation, and 22 others with presumed respiratory arrest; it did not deliver any inappropriate shocks to patients or to the rescuers using the device. An automatic external defibrillator can be used by first responders as an adjunct to basic life support, and its use may improve survival by shortening the time to defibrillation.

摘要

260名心脏骤停患者在护理人员到达之前由首批响应的消防员使用自动体外除颤器进行治疗。平均而言，首批响应者比护理人员提前5分钟到达。在118名心室颤动患者中，91名（77%）接受了电击，其中21名（23%）在护理人员到达时恢复了脉搏和血压。56名（62%）患者入院，30名（33%）存活。所有118名被发现心室颤动的受害者的存活率为27%。该设备正确分类了92名心搏停止、46名电机械分离以及22名推测为呼吸骤停患者的初始及所有后续心律；它没有对使用该设备的患者或救援人员进行任何不适当的电击。自动体外除颤器可被首批响应者用作基本生命支持的辅助设备，其使用可能通过缩短除颤时间来提高存活率。
