对术前无神经精神病史者,术后出现苏醒延迟或术中发生与手术无关的神经精神症状,是麻醉管理的重要课题。当今所使用的全麻药,只要浓度和剂量恰当,呼吸和循环管理正确,一般不会出现神经问题。麻醉和手术中出现脑功能障碍的原因以低氧血症和脑缺血为多。脑细胞的缺氧耐受力甚差,不同部位脑组织其耐受力也各异。耐受力差的部位(脆弱部位),其神经细胞死亡的时间和过程是一项复杂问题。本文就此加以讨论。
Preoperative no history of neuropsychiatric history, postoperative recovery or postoperative recurrence of surgery has nothing to do with neuropsychiatric symptoms, anesthesia management is an important issue. The anesthetics used today, as long as the right concentration and dose, respiratory and circulatory management is correct, the general does not appear neurological problems. Causes of brain dysfunction during anesthesia and surgery are mostly hypoxemia and cerebral ischemia. Hypoxic tolerance of brain cells is very poor, different parts of the brain tissue tolerance is also different. The poor tolerance of the site (vulnerable parts), the time and process of nerve cell death is a complex issue. This article discusses this.
