Postoperative recurarization remains a risk following the use of the conventional neuromuscular blocking agents. In addition, none of the commonly used reversal agents, such as neostigmine or edrophonium are capable of reliably reversing profound blockade. The present comparative and randomized study investigated the use of sugammadex for reversing profound neuromuscular blockade (NMB) in pediatric neurosurgical patients undergone posterior fossa tumor excision.
Forty pediatric patients undergoing elective craniotomy for posterior fossa tumor excision were randomly divided into either of neostigmine or sugammadex group in which muscle relaxant was reversed at the end of anesthesia either with neostigmine 0.04 mg/kg added to atropine 0.02 mg/kg or sugammadex 4 mg/kg alone, respectively. The primary endpoint was the time from the administration of sugammadex or neostigmine to recovery of the train of four (TOF) ratio to 90% after rocuronium-induced neuromuscular block. Unpaired t-test was used to compare continuous variables between groups. Meanwhile, repeated ANOVA was used to detect intragroup differences.
Patients in sugammadex group attained a TOF ratio 90% in statistically shorter time (1.4 ± 1.2 min) than those in neostigmine group (25.16 ± 6.49 min) for reversal of the rocuronium. Mean arterial pressure and heart rate were significantly higher in neostigmine group at 2, 5 and 10 min after administration of the reversal agents and returned nonsignificantly different after that. With no recurarization in any patient throughout the study period.
Sugammadex rapidly and effectively reverses rocuronium-induced NMB in pediatric patients undergoing neurosurgery when administered at reappearance of T2 of TOF at dose 4 mg/kg.
使用传统神经肌肉阻滞剂后,术后再次出现肌松残留仍是一种风险。此外,常用的逆转剂,如新斯的明或依酚氯铵,均无法可靠地逆转深度阻滞。本比较性随机研究调查了舒更葡糖在接受后颅窝肿瘤切除的小儿神经外科手术患者中逆转深度神经肌肉阻滞(NMB)的应用情况。
40例接受择期后颅窝肿瘤切除开颅手术的小儿患者被随机分为新斯的明组或舒更葡糖组,分别在麻醉结束时用0.04 mg/kg新斯的明加0.02 mg/kg阿托品或单独用4 mg/kg舒更葡糖逆转肌松药作用。主要终点是从给予舒更葡糖或新斯的明到罗库溴铵诱导的神经肌肉阻滞后四个成串刺激(TOF)比值恢复至90%的时间。采用独立样本t检验比较组间连续变量。同时,采用重复方差分析检测组内差异。
舒更葡糖组患者罗库溴铵逆转时达到TOF比值90%的时间在统计学上显著短于新斯的明组(1.4±1.2分钟 vs 25.16±6.49分钟)。给予逆转剂后2、5和10分钟时,新斯的明组平均动脉压和心率显著更高,之后恢复至无显著差异。在整个研究期间,所有患者均未出现肌松残留。
在小儿神经外科手术患者中,当TOF的T2出现时给予4 mg/kg剂量的舒更葡糖可快速有效地逆转罗库溴铵诱导的NMB。
