预注法联合限时法缩短顺苯磺酸阿曲库铵起效时间疗效观察

目的：研究预注法联合限时法缩短顺苯磺酸阿曲库铵起效时间的效果。方法：成年择期手术全麻患者112例按入院先后顺序分为甲乙丙3组,3组患者均使用芬太尼4μg·kg-1和丙泊酚2 mg·kg^-1作为诱导药。甲组采用预注法联合限时法,患者先静注顺苯磺酸阿曲库铵20μg·kg-1,3 min后再先后注射诱导药和顺苯磺酸阿曲库铵80μg·kg-1;乙组采用预注法,患者先静注顺苯磺酸阿曲库铵100μg·kg-1,1.5 min后注入诱导药;丙组采用限时法,患者先后注入诱导药与顺苯磺酸阿曲库铵l00μg·kg-1。观察比较各组诱导前T1百分比,肌肉颤搐抑制90%和100%的时间、气管插管评级以及药品不良反应。结果：3组患者气管插管优秀率比较,差异无统计学意义（P〉0.05）。与甲、乙组比较,丙组诱导前不存在T1抑制,乙组（9.8±2.6）多于甲组（3.2±1.5）（P〈0.01）;达肌肉颤搐抑制90%与100%时间,丙组明显长于甲、乙两组（P〈0.01）。丙组不良反应发生率明显高于甲、乙两组（P〈0.05）。结论：应用预注法以及限时法,均可有效缩短顺苯磺酸阿曲库铵的起效时间,效果显著,且安全性高。

Effect of Priming Technique Combined with Time Limit on Shortening the Onset time of Cisatracurium Besilate

Objective：To study the effect of priming technique combined with time limit on shortening the onset time of cisatracurium besilate. Methods：Totally 112 adult patients undergoing selective operation with general anesthesia were randomly divided into group A, B and C. Fentanyl with the dose of 4 μg·kg-1 and propofol with the dose of 2 mg·kg-1 were used in the three groups as the inducing agents. Group A was first with intravenous injection of cisatracurium besilate 20 μg·kg-1 , and 3 minutes later, the inducing agents and cisatracurium besilate with the dose of 80 μg·kg-1 were respectively injected. Group B was first with intravenous injection of cisatracurium besilate with the dose of l00 μg·kg-1 , and 1. 5 minutes later, the inducing agents were injected. Group C was respectively injected with the inducing drugs and cisatracurium besilate with the dose of l00 μg·kg-1 . The T1 percentage before the induction, the time of 90% and 100% inhibition of muscle twitching, the rating of trachea cannula and adverse drug reactions in the three groups were observed and compared. Results：There was no significant difference in the excellent rate of trachea cannula a-mong the three groups （P〉0. 05）. Compared with group A and B, group C showed no T1 suppression before the induction, while group B with T1 of （9. 8 ± 2. 6） was higher than group A with T1 of （3. 2 ± 1. 5） （P〈0. 01）. The time of 90% and 100% inhibition of muscle twitching in group C was the longest （P〈0. 01）, and the incidence of adverse drug reactions in group C was also the highest （P〈0. 05）. Conclusion：The application of priming principle and time limit can effectively shorten the onset time of cisatracurium besilate with significant effect and high safety.
