院外心搏骤停患者自主循环恢复影响因素分析

目的 分析院前急救过程中各因素对心搏骤停患者复苏成功率的影响,为院前心肺复苏提供可靠的理论依据。方法 对2019年1月至2020年6月年南京市急救中心接诊的3053例心搏骤停患者进行统计,院前实际救治1313例,共计48例患者自主循环恢复,对自主循环恢复(ROSC)成功的相关因素进行分析。结果 单因素分析结果显示,CPR开始时间、持续时间、初始心律、有无BLS、是否使用心肺复苏机、除颤、肾上腺素、气管插管,差异有统计学意义(P0.05);多因素回归分析显示,CPR开始时间、持续时间、初始心律、是否除颤,有无BLS、气管插管,以上因素对ROSC率的影响差异有统计学意义(P0.05)。结论 严谨规范的院前急救措施能显著提高ROSC成功率。

Analysis on the impacting factors of the return of spontaneous circulation in patients with cardiac arrest outside hospital

Objective To analyse the impacts of various factors on the success rate of resuscitation in patients with cardiac arrest in pre-hospital emergency,and to provide reliable theoretical basis for pre-hospital cardiopulmonary resuscitation.Methods A total of 3053 patients with cardiac arrest admitted to Nanjing Emergency Medical Center from January 2019 to June 2020 were statistically analyzed,and 1313 patients were actually treated with pre-hospital emergency,and 48 patients recovered from spontaneous circulation.The related factors of successful return of spontaneous circulation(ROSC) were analysed.Results Univariate analysis showed that there were statistically significant differences in CPR starting time,duration,initial heart rate,BLS condition,cardiopulmonary resuscitation condition,defibrillation,adrenaline and tracheal intubation (P<0.05).While multivariate regression analysis showed that there were impacts on CPR starting time,duration,initial heart rate,defibrillation,BLS condition and tracheal intubation on ROSC rate,with statistically significant differences(all P<0.05).Conclusion Rigorous and standard pre-hospital emergency measures can significantly improve the success rate of ROSC.
