摘要 目的探讨小剂量咪达唑仑联合丙泊酚镇静在非全身麻醉中的应用。方法选择在非全身麻醉下的外科、骨科手术60例,其中椎管内麻醉40例,臂丛神经阻滞20例,按随机数字表法分为Ⅰ组(MB组)待麻醉起效,麻醉平面到达预期效果,手术开始前用咪达唑仑0.02-0.04mg/kg,iv镇静,后用瑞芬太尼0.1-0.8μg/kg/min维持,Ⅱ组(M组)待麻醉平面到达预期效果,手术开始前单次用咪达唑仑0.02-0.04mg/kg iv镇静,Ⅲ组(对照组)按照常规方法进行,手术全程未使用镇静剂。监测和记录患者麻醉前(T1)、麻醉平面固定时(T2)、镇静后1分钟(T3)、10分钟(T4)、30分钟(T5)、60分钟(T6)、清醒后(T7)的BIS值、PETCO2、MAP、HR、SPO2,记录术中烦躁,恶心呕吐和呼吸抑制等不良反应发生率,苏醒时间及术后24小时随访的满意度。结果Ⅰ组Ⅱ组的MAP稍低于对照组(P〉0.05),术后24小时随访满意度Ⅰ组Ⅱ组明显高于对照组(P〈0.01),Ⅰ组满意度最高。结论非全身麻醉中静脉给予小剂量咪达唑仑和丙泊酚能给患者提供有效的镇静,对呼吸循环抑制轻,术后苏醒快,患者满意度高。
