心跳与呼吸停止病人的复苏效果,在很大程度上取决于神经系统功能的恢复。以往认为由于脑组织耗氧量很大,神经细胞代谢率极高,而能源储备有限,故中枢神经系统对缺氧的耐受性极差,其缺氧性损害远较其它脏器严重。而近十年来有实验报告,在一定条件下脑完全缺血长达60分钟后,某些神经细胞功能仍可恢复,北京、上海、南京心脏复苏小组报告12例循环骤停八分钟以上复苏成功。电子显微
The recovery of patients with heartbeat and respiratory arrest depends largely on the recovery of nervous system function. In the past that due to a large brain tissue oxygen consumption, high metabolic rate of nerve cells, and limited energy reserves, so the central nervous system tolerance to hypoxia very poor hypoxic damage far worse than other organs. In recent ten years, there are experimental reports that under certain conditions, the brain is completely ischemia for up to 60 minutes, some nerve cell functions can still be restored, Beijing, Shanghai and Nanjing heart resuscitation team reported 12 cases of circulatory arrest more than eight minutes recovery success .
