目的 :对比研究异丙酚和硫喷妥钠对琥珀胆碱肌松效应的影响。方法 :34例拟行喉显微手术病人随机分为两组 ,分别给予异丙酚或硫喷妥钠静脉复合麻醉。全麻诱导后 ,静注琥珀胆碱 1 5mg/kg后气管插管 ,继之连续静滴 0 1%琥珀胆碱溶液维持肌松状态至术毕 ,以加速度仪监测。结果与结论 :与硫喷妥钠组相比 ,异丙酚麻醉时琥珀胆碱的肌松起效更快 ,停药后肌松恢复也更快 Objective: To compare the effects of propofol and thiopental on the muscle relaxant effect of succinylcholine. Methods: Thirty-four patients undergoing throat microsurgery were randomly divided into two groups, and were given intravenous anesthesia with propofol or thiopental respectively. After induction of general anesthesia, intravenous injection of succinylcholine 1 5mg / kg after tracheal intubation, followed by continuous intravenous infusion of 0 1% succinylcholine to maintain muscle relaxation state to surgery, with accelerometer monitoring. RESULTS AND CONCLUSION: Compared with the thiopental group, succinylcholine had a more effective onset of muscle relaxant when anesthetized with propofol and faster recovery of muscle relaxant after stopping the drug
