摘要:

目的 探讨舒更葡糖钠逆转肝功能异常患者罗库溴铵神经肌肉阻滞效果的量效关系。方法 选取择期行肝部分切除术的患者80例。依据Child-Pugh分级情况将患者分为试验组(Child-Pugh分级A级)和对照组(肝功能正常),每组40例。于手术结束后强直刺激后单刺激肌颤搐计数(PTC)1~2次时即刻静脉注射舒更葡糖钠。2组患者均使用Dixon序贯法调整舒更葡糖钠用药剂量,首例患者静脉注射初始剂量舒更葡糖钠4 mg/kg,剂量梯度0.5 mg/kg。计算舒更葡糖钠的ED95结果 试验组患者术中罗库溴铵使用剂量明显低于对照组(P<0.05)。试验组和对照组患者的舒更葡糖钠最大使用剂量分别为5.5 mg/kg和4.5 mg/kg。对照组Probit模型公式为Probit(P)=-10.891+3.009×剂量,而试验组为Probit(P)=-8.095+1.864×剂量。舒更葡糖钠逆转对照组患者的罗库溴铵神经肌肉阻滞的ED95为4.167 mg/kg(95%CI:3.824~4.509 mg/kg);而舒更葡糖钠逆转试验组患者的为ED95为5.224 mg/kg(95%CI:4.577~5.872 mg/kg)。结论 与肝功能正常患者相比,肝功能异常患者需要更大剂量的舒更葡糖钠才可逆转罗库溴铵神经肌肉阻滞,其ED95为5.224 mg/kg。

Abstract:

Objective To investigate the dose-effect relationship of sugammadex sodium on reversing neuromuscular block of rocuronium in patients with liver dysfunction. Methods Eighty patients who underwent elective partial hepatectomy were selected. According to the Child-Pugh classification, patients were divided into the experimental group (Child-Pugh class A) and the control group (normal liver function), with 40 cases in each group. Sugammadex sodium was intravenously injected immediately after the operation at the time of 1-2 times of single-stimulated muscle twitch count (PTC) after tonic stimulation. Dixon sequential method was used to adjust the dosage of sugammadex sodium in both groups, and the first patient was intravenously injected with the initial dose of sugammadex sodium 4 mg/kg, with a dose gradient of 0.5 mg/kg. The ED95 of sugammadex sodium was calculated. Results The intraoperative dose of rocuronium bromide was significantly lower in the experimental group than that in the control group (P<0.05). The maximum dosage of sugammadex sodium was 5.5 mg/kg in the experimental group, and the maximum dosage of sugammadex was 4.5 mg/kg in the control group. The Probit model formula of the control group was Probit(P)=-10.891+3.009×dose, and the Probit model formula of the experimental group was Probit(P)=-8.095+1.864×dose. The ED95 of sugammadex sodium for reversing rocuronium bromide neuromuscular block was 4.167 mg/kg in patients of the control group (95%CI: 3.824-4.509 mg/kg). The ED95 of sugammadex sodium for reversing neuromuscular blockade in patients of the experimental group was 5.224 mg/kg (95%CI: 4.577-5.872 mg/kg). Conclusion Compared with patients with normal liver function, patients with abnormal liver function require a larger dose of sugammadex to reverse the neuromuscular blockade of rocuronium bromide, with an ED95 of 5.224 mg/kg.
