摘要 目的:观察右美托咪定复合帕瑞昔布对老年全髋置换患者瑞芬太尼输注后痛觉过敏的影响。方法:选择64例全髋关节置换手术老年患者,采用随机数字表法,分为试验组和对照组,各32例。试验组静注右美托咪定0.5μg/kg和帕瑞昔布钠40 mg;对照组静注等容量的0.9%氯化钠注射液,手术结束患者出手术室时给予自控静脉镇痛泵(PCIA)。比较两组患者拔管时间、恢复呼吸时间、不同时间点的VAS评分及不良事件发生率。结果:试验组拔管时间及呼吸恢复时间略长于对照组,平均手术时间短于对照组,但差异均无统计学意义(P>0.05)。试验组1、2、6、12、24 h各VAS评分均显著低于对照组,差异均有统计学意义(P<0.05)。两组均未见呼吸抑制;试验组未见寒战及躁动,与对照组比较,差异有统计学意义(P<0.05);试验组有轻微的恶心呕吐,与对照组比较,差异无统计学意义(P>0.05);两组均有轻微嗜睡,差异均无统计学意义(P>0.05);试验组1 d内镇痛药物追加率低于对照组,差异有统计学意义(P<0.05)。结论:右美托咪定复合帕瑞昔布对预防老年患者瑞芬太尼输注后痛觉过敏效果显著,术后寒战、躁动等不良事件发生率明显降低。
