小剂量利多卡因在无痛宫腔镜术中的应用

目的：观察静注利多卡因在无痛宫腔镜术的应用效果。方法：120例择期宫腔镜手术患者，随机均分为L、C两组。L组麻醉诱导前缓慢静脉推注利多卡因1mg／kg；C组以生理盐水替代。两组均静注丙泊酚1—1．5mg／kg进行麻醉诱导至睫毛反射消失，术中酌情追加丙泊酚。麻醉开始后，询问患者是否有静脉注射痛，观察记录术中及术后疼痛情况。结果：两组术中血压、心率平稳。L组较C组丙泊酚注射痛及术中术后疼痛程度减轻（P〈0．05）。结论：利多卡因复合丙泊酚用于无痛宫腔镜不良反应小，有利于病人术后恢复。

Application of Lidocaine in Painless Hysteroscopic Surgery

Objective： To investigate the effects of intravenous infusion of lidocaine in painless hysteroscopic surgery. Methords： 120 patients of selective painless hysteroscopic surgery were divided randomly into two groups of L and C. Before induction, group L was given lidocaine injection of 1.5mg/kg, Group C received normal saline instead of lidocaine as the control. Anesthesia was induced with propofol 1-1.5mg/kg till the Eyelash reflex disappeared and propofol was added as needed. After initiation of anesthesia, the pain of injection and the Intraoperative and Postoperative pain was recorded. Results： BP and HR of two groups were stable. Compaired with group C, the degree of injection pain of propofol and the Intraoperative and Postoperative pain was reduced. Conclution： Use of lido- caine-propofol in painless hysteroscopic surgery could be in favor of patients recovery with less adverse reactions.
