罗哌卡因与布比卡因相比,安全范围较宽,对中枢神经系统和心血管的副反应均较弱。罗哌卡因阻滞感觉神经敏感度较高,而且较少发生运动阻滞。因此给患儿使用罗哌卡因阻滞,术后恢复就比较迅速。 作者选择60例ASAⅠ级,3～6岁行下腹部手术(睾丸固定)的患儿。不用术前药,静注异丙酚3mg/kg、1％利多卡因0.5mg/kg,和阿芬太尼30μg/kg诱导,静注琥珀胆碱 Compared with bupivacaine, ropivacaine has a wide range of safety and weak side effects on central nervous system and cardiovascular. Ropivacaine sensory nerve block sensation higher, and less motor block. Therefore, children with ropivacaine block, postoperative recovery is relatively rapid. The authors selected 60 ASA grade I, 3-6-year-old children who underwent abdominal surgery (testicular fixation). Without premedication, intravenous propofol 3 mg / kg, 1% lidocaine 0.5 mg / kg, and alfentanil 30 μg / kg were induced by intravenous injection of succinylcholine
