摘要:  目的: 观察罗哌卡因臂丛神经阻滞复合氯胺酮-丙泊酚静脉麻醉在小儿上肢手术中应用,对呼吸循环功能以及术后恢复情况的影响.方法: 50例行上肢手术患儿随机分为两组:氯胺酮基础麻醉后,臂丛神经阻滞复合氯胺酮-丙泊酚静脉麻醉组(A组,n=25),臂丛阻滞成功后注入0.25%罗哌卡因0.5ml/kg,术中以氯胺酮-丙泊酚持续静注;单纯氯胺酮-丙泊酚静脉麻醉组(B组,n=25),术中氯胺酮-丙泊酚持续静注.结果: 术中A组循环、呼吸功能较B组稳定(P<0.05);肢体不良自主运动,喉痉挛等不良反应较B组少(P<0.05);A组氯胺酮用量明显少于B组(P<0.01);术后A组苏醒较快且平稳.恢复期精神症状少,与B组比较有显著差异(P<0.05).结论: 臂丛神经阻滞复合氮胺酮-丙泊酚静脉麻醉应用于小儿上肢手术,可减少氯胺酮用量从而减少其不良反应,使患儿在麻醉手术期间呼吸循环更平稳,家长及医护人员满意度明显提高.
