摘要 目的:探讨纳洛酮复合吗啡应用于术后硬膜外镇痛的临床效果及安全性。方法:60例ASA1-2级妇科术后患者,随机分成三组,A组(观察组Ⅰ,N=20),B组(观察组Ⅱ,N=20),C组(对照组ⅢN=20)。术毕:A组,首量纳洛酮0.1 mg+吗啡2 mg+0.125g布比卡因共10 ml。维持,纳洛酮0.4 mg+吗啡6 mg+0.125g布比卡因共100 ml。B组:首量纳洛酮0.05 mg+吗啡2 mg+0.125g布比卡因共10 ml。维持,纳洛酮0.2 mg+吗啡6 mg+0.125g布比卡因共100 ml。C组,首量吗啡2 mg+0.125g布比卡因共10 ml。维持,吗啡8 mg+0.125g布比卡因共100 ml(镇痛泵2 ml/hr),比较三组的镇痛效果(VSA),运动神经阻滞程度、血氧饱和度(sPO2)、血压(BP)、呼吸(R)、心率(HR)、以及不良反应。以统计学分析结果。结果:三组患者术后的疼痛成度大致相同(P〉0.05)。恶心呕吐术后3-36hr内,A组明显轻于B组、C组(P〈0.05)。搔痒术后6-12hr内,24-36hr内,B组明显轻于C组(P〈0.05)。12-24hr内A组明显轻于C组(P〈0.05)。三组患者术后48hr内,下肢活动无明显差异(P〈0.05)。三组无呼吸抑制。结论:纳洛酮复合吗啡应用于术后硬膜外镇痛,安全有效,能有效的改善恶心呕吐、搔痒、减少吗啡的用量。
