摘要
目的 评价不同给药方式对肝移植术中顺式阿曲库铵临床药效学的影响.方法 择期肝移植术患者24例,年龄18 ～ 63岁,体重60 ～ 88 kg,BMI 20 ～ 30 kg/m2,性别不限,ASA分级Ⅲ级,采用随机数字表法,将其分为2组（n=12）：连续静脉输注组（C组）和间断静脉注射组（I组）.采用全凭静脉全身麻醉,麻醉诱导后待肌松监测仪显示T1恢复至10％时,C组开始静脉输注顺式阿曲库铵,初始速率1.5 μg· kg-1 ·min-1,调节输注速率,维持T1在10％左右,I组间断静脉注射0.03 mg/kg顺式阿曲库铵,维持T1≤10％,待腹膜关闭后即刻停止使用肌松药.记录顺式阿曲库铵的单位时间用药量、T1由10％恢复至25％的时间、恢复指数和术后自主呼吸恢复的时间.结果 与I组相比,C组顺式阿曲库铵单位时间用药量减少,术后自主呼吸恢复时间缩短（P＜0.05）,T1恢复至25％的时间和恢复指数差异均无统计学意义（P＞0.05）.结论 与间断静脉注射相比,肝移植术中静脉输注顺式阿曲库铵有助于提高临床肌松效应的效价,有利于减少麻醉恢复期相关并发症的发生.
Objective To evaluate the effects of different methods of administration on clinical pharmacodynamics of cisatracurium during liver transplantation.Methods Twenty-four ASA physical status Ⅲ patients of both sexes,aged 18-63 yr,weighing 60-88 kg,with body mass index of 20-30 kg/m2,scheduled for elective liver transplantation,were randomly divided into 2 groups （n =12 each）：continuous infusion group （group C） and intermittent bolus injection group （group Ⅰ）.The total intravenous anesthesia was used during surgery.When T1 recovered to 10％ of control height after induction of anesthesia,continuous infusion of cisatracurium was started with an initial rate of 1.5 μg· kg-1 · min-1,and the infusion rate was manually adjusted to maintain T1 at about 10％ in group C,and intermittent iv boluses of cisatracurium 0.03 mg/kg were given to maintain T1 ≤ 10％ in group Ⅰ.The use of muscle relaxants was stopped immediately after peritoneum closure.The consumption of cisatracurium per minute,time for T1 to recover from 10％ to 25％,recovery index and time for recovery of spontaneous breathing after surgery were recorded.Results Compared with group Ⅰ,the consumption of cisatracurium per minute was significantly reduced and the time for recovery of spontaneous breathing after surgery was shortened （P ＜ 0.05）,and no significant changes were found in the time for T1 to recover from 10％ to 25％ and recovery index in group C （P ＞ 0.05）.Conclusion Compared with intermittent bolus injection,continuous infusion of cisatracurium during liver transplantation is helpful in improving the clinical potency of the muscle relaxant and in reducing the occurrence of complications during anesthesia recovery period.
