摘要 目的:比较右美托咪定复合小剂量瑞芬太尼与单纯右美托咪定用于颈椎后路椎间孔镜手术的临床效果。方法:选择我院64例ASAⅠ-Ⅱ级颈椎病实施椎间孔镜手术的患者,按数字表法随机分为A组(观察组,n=32例)和B组(对照组,n=32例);两组均采用0.5%利多卡因与0.375%的罗哌卡因混合液局部浸润麻醉,切皮前10min,A、B两组均泵入:负荷量右美托咪定0.5μg/kg,持续量0.2μg~0.8μg/kg/h,A组增加瑞芬太尼0.1μg/kg/min持续泵入;两组术毕前15min均停药。观察及记录给药前(T_(0))、给药后10min(T_(1))手术开始切皮(T_(2))、打磨椎板及显露神经根(T_(3))、手术结束(T 4)等时间点的HR、MAP、SPO_(2)及警觉/镇静OAA/S评分,记录患者术中的不适反应:如疼痛、体动、不配合手术等。结果:A组在T_(2)、T_(3)时间点HR、MAP、OAA/S评分优于B组,差异有统计学意义(P<0.05);B组术中不适反应有6例(18.75%),A组1例(3.12%),差异有统计学意义(P<0.05)。结论:右美托咪定复合小剂量瑞芬太尼明显提高颈椎后路椎间孔镜手术患者镇静镇痛效果,减少患者术中的不适反应。
