We compared the effect of rapid defibrillation by emergency medical technicians (EMTs) combined with paramedic care with that of standard EMT and paramedic care on survival from 540 witnessed episodes of out-of-hospital cardiac arrest caused by ventricular fibrillation. More than 400 EMTs were trained in the recognition of ventricular fibrillation and operation of a defibrillator. For a portion of the three-year study, emergency care for 179 cases was randomized between the two types of services. For randomized cases, when the time interval between EMT and paramedic arrival was greater than four minutes there was significantly improved survival with EMT defibrillation and paramedic care (42%) compared with basic EMT and paramedic care (19%). Similar findings occurred when all cases were considered (38% v 18%). Defibrillation by EMTs combined with paramedic services can enhance survival from ventricular fibrillation, compared with basic EMT and paramedic care.
我们比较了紧急医疗技术人员（EMT）进行快速除颤并结合护理人员护理与标准EMT和护理人员护理对540例因室颤导致的院外心脏骤停目击事件患者生存率的影响。400多名EMT接受了室颤识别和除颤器操作培训。在为期三年的研究的一部分中，179例病例的急救服务在两种类型之间随机分配。对于随机分组的病例，当EMT和护理人员到达的时间间隔大于4分钟时，与基本的EMT和护理人员护理（19%）相比，EMT除颤并结合护理人员护理的患者生存率显著提高（42%）。当考虑所有病例时也出现了类似的结果（38%对18%）。与基本的EMT和护理人员护理相比，EMT进行除颤并结合护理人员服务可提高室颤患者的生存率。
