心室颤动病人复苏的影响因素

Factors influencing outcome of resuscitation for patients with ventricular fibrillation

目的 探讨心室颤动 (室颤 )病人即刻复苏成功的影响因素。方法 回顾分析 43例经心电监测或心电图证实的室颤病人的复苏结果及基本病因、心功能、开始直流电除颤时间对复苏结果的影响。心功能评价采用 NYHA 4级分类法。结果 43例中复苏成功 2 3例 ,复苏成功率 5 3.5 %。急性心肌梗死 ( AMI)室颤病人的复苏成功率 ( 85 .7% )高于其他病因引起的室颤 ( 4 7.2 % ) ,但统计学分析差异无显著性意义 ( P >0 .0 5 ) ;心功能正常者复苏成功率 ( 92 .9% )高于心功能不全者 ( 34.5 % ) ( P <0 .0 5 ) ,发生室颤后 3min内启动除颤者复苏成功率 ( 62 .5 % )高于 3min后启动除颤者 ( 2 7.3% ) ( P <0 .0 5 )。结论 AMI引起的室颤病人抢救成功率高 ,除颤实施及时与否和患者心功能状态影响抢救成功率。

Objective To investigate the factors which influenced outcome of resuscitation for patients with ventricular fibrillation(VF).Methods Factors of resuscitation, etiology ,cardiac function, and time between heart attack and defibrillation were retrospectively analyzed for 43 cases with VF confirmed by electrocardiogram (ECG) monitor and ECG recorder ,NYHA criteria was used in cardiac function evaluation.Results Of 43 cases with VF ,23 cases were successfully rescued. Success rate of resuscitation was 85.7% in acute myocardial infarction(AMI) group and 47.2% in other etiology group, respectively. But no statistical significance between two groups(P>0.05). Success rate of resuscitation was 92.9% in normal cardiac function group, and 34.5% in cardiac dysfunction group. There was significantly different between two groups(P<0.05). Success rate of resuscitation in performed defibrillation within 3 minutes after attack group was 62.5% , which was higher than that performed defibrillation more than 3 minutes (P<0.05).Conclusions Success rate of resuscitation in AMI patients with VF was higher, and which was influenced by the time between VF attack and defibrillation, and cardiac function.
