肌松药微量输注法在喉显微外科手术中的应用

Application of Micro-injection Pump in Succinycholine Infusion in Microlarygeal Surgery

目的观察微量泵输注琥珀胆碱与普通静脉滴注法用于全麻下喉显微外科手术的效果。方法择期行全麻下喉显微手术患者40例,分为微量泵注组与普通静脉滴注组。对比2组术中肌松效果、用药量、术毕自主呼吸和意识恢复时间。结果与通静脉滴注组相比,微量泵注组的术中肌松效果好,用药量少,术毕自主呼吸和意识恢复时间明显缩短(P<0.05)。结论琥珀胆碱微量泵输注法便于术中调控,利于术后自主呼吸恢复。

Objective To observe the effect of using micro--injection pump or traditional intravenous infusion to infuse succinycholine in microlarygeal surgery. Methods 40 patients who received microlarygeal surgery were divided randomly into micro--injection pump group and traditional infusion group. The effect of muscle relaxation, total amount of suecinyeholine and spontaneous breathing recovery time were recorded. Results Compared with traditional infusion group, muscle relaxation of microinjection pump group was better, spontaneous breathing recovery time was shorter, total amount of succinycholine was smaller （P 〈 0.05）. Conclusions Using micro--injection pump to infuse succinycholine in microlarygeal surgery is convenient for satisfactory muscle relaxation during operation and spontaneous breathing recovery post operation.
