全麻维持方式与术后寒战的关系

Relationship between maintenance types of general anesthesia and postoperative shivering

目的 研究不同的全麻维持方式对术后寒战的影响。方法 随机采用全吸入、静吸复合及全静脉维持麻醉 ,观察三组病人寒战发生率、术后出现寒战的时间及级别、鼓膜温度的变化。结果 三组寒战发生率比较无显著性差异 ;吸入组出现寒战的时间比静脉组显著缩短 ,寒战最高级别三组无显著性差异。三组病人术后鼓膜温度都显著低于诱导后 10分钟的温度 ,吸入组降低最多 ,静脉组降低最少。结论 预防术后寒战 ,全静脉维持麻醉显著优于全吸入维持麻醉。

Objective To research the effect of different maintenance types of general anesthesia on postoperative shivering.Methods The maintenance types of general anesthesia were randomly used in patients whose anesthetics were totally inhaled,intravenously infused plus inhaled,and totally intravenously infused.The occurrence rate of postoperative shivering,the occurrence time and scores of shivering after operation and the changes of tympanic temperatures were observed.Results There was no significant difference in occurrence rate of shivering among three groups.The occurrence time of shivering in inhaled group was significantly shorter than that in totally intravenously infused group.The highest scores of shivering were not significantly different among three groups.The tympanic temperatures after operation were significantly lower than those at 10 minutes after induction in all three groups,the extent of decrease was most in inhaled group and lowest in intravenous infused group.Conclusions Total intravenous maintenance anesthesia has a significant more advantage than inhaled maintenance anesthesia in prevention of postoperative shivering.
