目的: 将不同麻醉深度下进行无抽搐电休克治疗( MECT) 后的谵妄发生率进行对比研究，探讨加深 麻醉对改善 MECT 后谵妄的作用。方法: 将 2017－09～ 2018－12 期间，在内蒙古精神卫生中心接受 MECT 治疗并 符合入组标准的 116 例精神分裂症病人随机分为 A、B 两组，在治疗中分别给予1．2mg /kg 和1．6mg /kg 的丙泊酚 进行麻醉，对治疗后谵妄发生率进行对比分析。结果: B 组谵妄发生率明显低于 A 组( P＜0．05) 。结论: 适当增 加麻醉深度在同等条件下可以有效降低 MECT 治疗后谵妄的发生。

Objective: The incidences of delirium after modified electroconvulsive therapy( MECT) under different anesthesia depths were compared，and the effect of deepening anesthesia on improving delirium after MECT were explored．Methods: During September 2017 to December 2018，116 schizo- phrenia patients who were received MECT in Inner Mongolia Mental Health Center and met the require- ment for research were randomized into too groups: group A and group B．The patients in group A were anesthetized by intravenous injection of propofol at a dose of 1．2mg /kg，and the patients in Group B were anesthetized by intravenous injection of propofol at a dose of 1．6mg /kg．Finally，we compared and analyzed the incidences rate of delirium after MECT in two groups．Ｒesults: The incidence rate of deliri- um in group B was obviously lower than that in group A( P＜0．05) ．Conclusion: With the same condi- tions，appropriately deepening the depth of anesthesia can effectively reduce the incidence of delirium after MECT．
