心肺复苏急救效能影响因素分析

目的探讨院前院内CPR急救效能影响因素。方法应用SPSS11.0软件对经过CPR急救的386例CA病例生存入院、ROSC的影响因素进行组间两两χ2检验分析。结果 〈5min CPR组分别与目击者急救组、〈5min除颤组及VF组转复成功、≤10min应用肾上腺素累计≤4mg,P均〈0.05或〈0.01,差异有统计学意义;与气管插管运用组χ2=4.540.05〉P〉0.01;〉10min CPR无生存入院、〉5min除颤无转复成功。结论院前院内CPR急救效能影响因素：目击者及时反应、首次CPR时机、除颤时机与除颤心律表现、气管插管、肾上腺素累计用药。生存入院随首次CPR和除颤时机的延长呈下降负相关线性回归趋势;与目击者急救和VF呈正相关线性回归趋势。

The analysis of the influencing factors on the effect of cardiopulmonary resuscitation

Objective To discuss the influencing factors on the effect of pre-hospital and in-hospital cardiopulmonary resuscitation（CPR）.Methods to analyzer 386 CA cases rescued by CPR and ROSC influencing factors tested by χ2 SPSS11.0 was used to analyze the datas.Results comparing the CPR group less than 5 minutes since found group with defibrillation less than 5 minutes since found group,VF cardioversion group and the epinephrine group（total mount ≤4mg）,significant difference was found P0.05 or0.01.with intubation group,χ2 =4.54,0.05P0.01.There were no survives if CPR started 10 minutes since cardioareest found,no survives in debrillation 5minutes either.Conclusion The witness response time,timing of first CPR,the cardiac rhythm when defibrillation and the use of epinephrine were all the factors that can influence the efficiency of in-hospital CPR.The survival and hospitalization rate demonstrate to be Negative correlation linear regression trend with the delay of first CPR and timing of first defibrillation,but positive correlation linear regression trend with the timing of admitted to hospital by witness.
