摘要 目的探讨间断静脉注射(IBI)、持续静脉输注(CI)和靶浓度控制输注(TCI)三种给药方式对老年手术患者罗库溴铵肌松效应的影响。方法选择全身麻醉下行手术治疗、年龄≥65岁的患者60例,随机分为IBI组、CI组和TCI组各20例。采用TOF-Watch SX肌松监测仪行神经肌肉传导功能监测。IBI组和CI组快速静脉注射罗库溴铵0.6 mg/kg后行气管插管,TCI组诱导期效应室靶浓度设定为3μg/ml,插管后将靶浓度降至1.0μg/ml,以0.2μg/ml递增或递减,维持T1颤搐高度(T1)与对照值(Tc)的比值(T1/Tc)在5%~10%;CI组当T1/Tc恢复至10%后开始以4μg·kg-1·min-1持续输注罗库溴铵,调整速率,维持T1/Tc在5%~10%;IBI组当T1/Tc恢复至10%时静脉注射罗库溴铵0.15 mg/kg。记录罗库溴铵起效时间,停用肌松药后T1/Tc恢复至25%的时间(T1/Tc 25%)、恢复指数(T1/Tc从25%恢复至75%的时间),四个成串刺激(TOF)比值(T4/T1)恢复至90%的时间(TOF90%),计算单位时间罗库溴铵使用量。结果 IBI、CI、TCI组各有18、19、18例患者的资料纳入统计。IBI组和CI组罗库溴铵起效快于TCI组(P〈0.05)。停用罗库溴铵后,IBI组T1/Tc 25%、恢复指数和TOF 90%长于CI组和TCI组(P〈0.05),CI组和TCI组相比无差异(P〉0.05)。TCI组术中罗库溴铵平均用量高于IBI和CI组(P〈0.05),IBI和CI组肌松药用量无差异(P〉0.05)。结论在老年患者中采用效应室靶浓度3μg/ml的罗库溴铵进行诱导时,肌松效应显现较慢;术中以TCI或CI方式给予罗库溴铵,停药后患者神经肌肉传导功能恢复较迅速。
