目的观察脑死亡后患者的心跳停止时间。方法对符合临床脑死亡标准者进行动态脑电图(EEG)检查(1~2次/d),直至EEG呈一条直线,24h后复查EEG仍呈一条直线者,记录、统计各例患者EEG检查呈一条直线的时间及心跳停止时间。结果42例符合脑死亡标准,心跳停止时间为19~359h。结论基于本地医疗条件及现状,一旦处于脑死亡状态,均于15d内出现心跳停止,心跳能维持9d者所占比例较大。 Objective To observe the cardiac arrest time of patients after brain death. Methods EEG (1 ~ 2 times / d) was performed in patients with clinical brain death criteria until the EEG showed a straight line. After 24 hours, the EEG still showed a straight line. EEG examination was recorded and counted in all cases A straight line of time and heartbeat stop time. Results 42 cases met the standard of brain death, heartbeat time was 19 ~ 359h. Conclusion Based on the local medical conditions and current status, once the brain is dead, all patients have a cardiac arrest within 15 days, and their heart rate can maintain a relatively high proportion of 9 days.
