创伤因素和非创伤因素致死率的回顾性分析

Retrospective Analysis of Traumatic and Non-traumatic Mortality

目的观察院前急救中创伤因素和非创伤因素致人死亡数量和死亡率的差异性。方法将德阳市第二人民医院2009年1月1日-2010年12月31日实施院前急救的3934例伤(病)员中死亡的202例伤(病)员,根据致死原因分组,因外力损伤经院前急救无效死亡的分入创伤因素致死组,因疾病经院前急救无效死亡分入非创伤因素致死组。将创伤因素致死组和非创伤因素致死组死亡的人数和死亡率进行统计学对比分析,观察院前急救中创伤因素和非创伤因素致人死亡数量和死亡率的差异性。结果创伤因素致死组,急救2657例,死亡89例,死亡率3.35%;非创伤因素致死组,急救1277例,死亡113例,死亡率8.85%;两组在院前急救中的死亡人数,经χ2检验,死亡率经U检验,均P<0.01,差异有统计学意义。即在急救半径内,非创伤性因素致人死亡数量、死亡率明显高于创伤因素致人死亡数量、死亡率。结论应重点加强非创伤性急症院前急救技能和心肺复苏的培训工作,提升院前急救质量。

Objective To evaluate the difference in deaths and death rates of the emergency firstaided patients caused by traumatic and nontraumatic diseases. Methods From January 1,2009 to December 31,2010,3934 emergency first aid patients were admitted in our hospital, among which 202 were dead. Of the dead patients, two groups were divided according to the death caused, because of external injury first aid before hospital death into the trauma death group, because of nontraumatic diseases first aid before hospital death into non trauma factors lethal group. The trauma death group and non trauma death group deaths and mortality were statistically analyzed, prehospital emergency trauma factors and non trauma deaths caused ＂by the volume and mor tality differences were observed. Results In trauma death group, among 2657 emergency first aid patients, 89 eases died, with mortality of 3.35% ;in nontrauma death group, 113 cases among 1277 were dead, the mortality was 8.85% ;two groups in pre hospital emergency care in the death toll, according to X2 test, mortality and tested by U, all P 〈 0. O1, there were significant differ ences. In my first aid radius,non traumatic factors causing death, mortality rate was higher than the number of deaths caused by the trauma, mortality number. Conclusion Strengthening non traumatic emergency prehospital firstaid skills and cardiopulmo nary resuscitation training should be focused on, and the quality of prehospital emergency care should be enhanced.
