摘要: 目的: 研究左旋布比卡因用于小儿患者臂丛神经阻滞的药代动力学特性。方法: 9例行择期上肢手术小儿患者,分别予 0.375%左旋布比卡因(0.4 mL/kg)行肌间沟入路臂丛神经阻滞。于注药后10、20、30、45、60、90、120、180、240、360、480和 720 min 测定左旋布比卡因血药浓度,3P97软件计算药代动力学参数。结果: 左旋布比卡因血药浓度-时间数据符合二房室开放模型,主要药代动力学参数消除半衰期(t1/2β) 、达峰时间(Tmax) 和峰值浓度(Cmax )分别为 (4.77±0.52) 、(0.28±0.14) h 和(1.02±0.22) mg/L。结论: 0.375%左旋布比卡因可安全用于小儿臂丛神经阻滞,其临床药代动力学符合二房室开放模型。

Abstract: AIM: To evaluate the clinical pharmacokinetics of levobupivacaine for brachial plexus block in pediatric patients. METHODS: 9 pediatric patients,undergoing elective upper shoulder surgery,were injected with levobupivacaine 0.375﹪(0.4 mL/kg)for interscalene brachial plexus block.The plasma concentration of levobupivacaine were determined at 10,20,30,45,60,90,120,180,240,360,480 and 840 min after injection,and the pharmacokinetic parameters were calculated with 3P97 software package. RESULTS: The plasma concentration-time curve was fitted to a two-compartment model,and the main pharmacokinetic parameter such as t1/2β,tmax and Cmax was (4.77±0.52),(0.28±0.14) h and (1.02±0.22) mg/L. CONCLUSION: Levobupivacaine 0.375% can be used for brachial plexus block in children safely,and its clinical pharmacokinetics is fitted to a two-compartment model.
