【摘要】:目的评价右美托咪定复合舒芬太尼在下肢骨折患者术后静脉自控镇痛(PCIA)中的应用效果。方法 150例择期全麻下行下肢骨折切开复位内固定患者,美国麻醉师协会(ASA)分级为Ⅰ~Ⅱ级,随机均等分为5组:不同剂量舒芬太尼组(S1、S2组),舒芬太尼复合不同剂量右美托咪定组(M1、M2、M3组)。于手术结束即刻行PCIA,均用生理盐水稀释至100 ml,首次剂量均为舒芬太尼0.1μg/kg,静脉镇痛泵背景输注速度2 ml/h,自控给药剂量0.5 ml,锁定时间15min。分别于术后1(T1)、3(T2)、6(T3)、12(T4)、24(T5)和48 h(T6)各时间点,采用视觉模拟评分法(VAS)评价患者疼痛程度及Ramsay镇静评分评价患者镇静程度;记录患者术后48 h内PCIA按压总次数及地佐辛用量;并记录术后48 h内恶心、呕吐、皮肤瘙痒、呼吸抑制和低血压的发生情况。结果与S1、M1组比较,S2、M2、M3组T1~T6 VAS评分降低(P0.05),M3组T1~T6 Ramsay评分升高(P0.05),S2、M2、M3组PCIA按压总次数及地佐辛消耗量均减少(P0.05)。M2组未出现并发症,S2组较S1、M1、M2、M3组恶心呕吐、皮肤瘙痒、呼吸抑制发生例数增加(P0.05);M2、M3组较S1组恶心呕吐发生例数减少(P0.05);M3组较M2组呼吸抑制发生例数增加(P0.05);M3组较S1、S2、M1、M2组低血压发生例数增加(P0.05)。结论 2μg/kg舒芬太尼联合2μg/kg右美托咪定镇痛效果满意,副反应少,是骨科患者术后镇痛的较佳配方。
