我国大中城市院前心脏性猝死流行病学调查分析

目的调查我国大中城市院前心脏性猝死患者流行病学情况，探讨院前心脏性猝死病例特点。方法从我国8个大中城市急救中心系统数据库中导出2008年度全部死亡数据，就其有完整记录的资料进行统计分析。结果①院前心脏性猝死的调度时间、到达时间、现场时间、返回时间、总时间、急救半径分别为（2．12±1．02）min、（14．10±7．05）min、（24．79±12．08）min、（13．79±6．61）min、（54．80±25．36）min、7．90±3．92（km）；②院前心脏性猝死的病例数以第一季度为最多，且最多时间段是8：00～10：00，最少时间段是2：00～4：00；③男性院前心脏性猝死明显多于女性，但年龄明显小于女性；④院前心脏性猝死目击者CPR为4．48％，医护人员现场CPR成功率2．26％。结论①心脏性猝死已成为我国大中城市最常见的院前死亡原因；②加强心血管病防治，提高中老年患者的常见急危重症早期识别与院前急救水平以及普及公众CPR对降低死亡有重要意义。

The epidemiological analysis of patients in pre-hospital sudden cardiac death for our large and medium sized cities

Objective To investigate the epidemiological information of patients in pre-hospital sudden cardiac death for our large and medium-sized cities and probe the patients' characteristic. Methods The death data in 2008 were exported from the computer databases of 8 large and medium-sized cities' emergency medical centers in our country. The thorough records of death data were conducted to statistical analysis. Results ①The scheduling time, running time, rescue time, returning time, total time and service radius in the sudden cardiac death group were (2. 12 ± 1.02 ), ( 14. 10 ± 7. 05 ), (24. 79 ± 12.08 ), ( 13.79 ± 6.61 ), (54. 80 ± 25. 36 ) minutes and 7.90 ± 3.92 (km)respectively. ②The patients' amount of sudden cardiac death group was at most in first quarter, and the most time slice of patients' amount was 8:00 ～ 10:00, and the least time slice of patients' amount was 2:00 ～ 4:00. ③The sudden cardiac death amount of male patients was more than that of female patients, and its age was less than that of female patients. ④The percentage of witness' CPR was 4.48%, and the success rates of medical care personnel' CPR was 2. 26%. Conclusion ①The sudden cardiac death is the overriding reason of death in our large and medium-sized cities. ②It is very important to cut the death rate of the middle-old age patients by strengthening prevention and cure of cardiovascular diseases, discerning the critical illness early,improving the level of pre-hospital medical care and popularizing CPR to public.
