院外心脏骤停现场自主循环恢复患者的流行病学研究

摘要

目的:分析院外心脏骤停(OHCA)现场自主循环恢复(ROSC)患者的流行病学特点.方法:参照Utstein模式,收集2012年1月至2016年12月,河南省人民医院院前120出诊的心脏骤停(CA)现场ROSC患者的临床资料,根据数据特点采用SPSS 20.0软件分析.结果:纳入29例患者,ROSC≥6 h的有9例(31.03%),ROSC<6 h的有20例(68.97%).两组患者在年龄、性别、初始发生地点、是否有目击者、是否提供CPR、初始心律、病因、抢救用肾上腺素方面差异均无统计学意义.ROSC≥6 h的患者中,无人生存出院.平均住院时间为(44.15±34.16)h,最短住院时间为12.08 h,最长住院时间为125.75 h.所有患者的急救反应时间(min)与返院时间(min)相比(6.45±3.60 vs.4.55±2.46,P=0.014),急救反应时间耗时更多.结论:现场ROSC的患者其入院生存率低,OHCA的发生需要早期预防.OHCA现场ROSC患者的短期生存时间(6h)不受患者基本情况及急救情况的影响.%Objective To investigate the epidemiological features of out-of-hospital cardiac arrest (OHCA) patients who are return of spontaneous circulation (ROSC) on scene. Methods According to Utstein style,we collected the clinical data of OHCA patients who are ROSC on scene from the pre-hospital on the call of 120 of Henan Provincial People ' s Hospital from January 2012 to December 2016. We analyzed the data by SPSS 20.0 software. Results Among a total of 29 patients were enrolled,9(31.03%)were ROSC ≥ 6h,and 20 (68.97%)were ROSC < 6 h. There were no significant difference in the two groups in patients' age,sex,arrest location,witnessed by bystander,bystander CPR,initial arrest rhythm,etiology,the use of epinephrine. None of patients were survival in the group of ROSC≥6 h. The average length of hospital stay was(44.15 ± 34.16)hours, while the shortest length of hospital stay was 12.08 hours and the longest length of hospital stay was 125.75 hours. The ratio of emergency response time to the return to hospital time were 4.55 min ± 2.46 min vs 6.45 min ± 3.60 min,P=0.014 in all patients. The emergency response time consumes more time. Conclusion The hospitalized survival rate of ROSC patients is low. The occurrence of OHCA needs early prevention. The short-term survival(6 h)is not affected by the patients' basic situation and the first-aid situation.
