Out-of hospital cardiac arrests in Hiroshima-Utstein style reporting from a Japanese million city

对广岛市(总人口106万)院外心脏骤停患者的预后按Utstein方式进行分析。从1998年9月到2002年12月，接受心肺复苏的心脏骤停患者有2,086人。因心脏原因导致的心脏骤停人数为1,041人，旁观者目击的病例为403人。出现心源性室颤(VF)和无脉性室性心动过速(VT)116例。发生心源性室性心动过速和无脉性室性心动过速的紧急救生技术人员(ELST)为22人。15名被旁观者活着出院的患者出现了心源性室颤和无脉性室速(12.9%)，11例来自Elsts的患者出现了心源性VF和无脉性VT(50%)。在本研究期间，广岛建立了医疗控制系统(MC)，并于2003年4月允许ELSTS进行除颤(DC)。本研究的方法和结果现在被认为是广岛MC系统的关键。这一事实使我成为广岛MC委员会的成员之一，我在该市从事心脏骤停治疗的培训项目。本研究的结果被承诺作为一个对照数据，以期在得到DC的许可后，心脏骤停幸存者的预期增加具有长期秩序。

Outcome of patients suffered from out-of-hospital cardiac arrest in Hiroshima city (1.06 million in population) were analyzed according to the Utstein style. Cardiac arrest patients who were received cardiopulmonary resuscitation were 2,086 from September 1998 to December 2002. The number of cardiac arrest by cardiogenic origin was 1,041, and of cases that were witnessed by bystanders were 403. The number of witnessed cardiogenic ventricular fibrillation (VF) and pulseless ventricular tachycardia (VT) was 116. The number of Emergency Life Saving Technicians (ELSTs) witnessed cardiogenic VF and pulseless VT was 22. Fifteen patients discharged to home alive from bystander witnessed cardiogenic VF and pulseless VT (12.9%), and 11 patients did from ELSTs witnessed cardiogenic VF and pulseless VT (50%).A medical control (MC) system in Hiroshima was established during a period of this study, and defibrillation (DC) by ELSTs with a standing order was permitted in April, 2003. The methodology and results of the present study are now admitted as essential for MC system in Hiroshima. This fact made me one of the members of the MC committee in Hiroshima, and I am engaged in training programs for the treatment of cardiac arrest in the city. The results of the present study are promised to be a control data to expected increase in survivors from cardiac arrest after the permission of DC by ELSTs with a standing order.
