摘要
目的观察罗哌卡因复合右美托咪定对低位肌间沟入路臂丛神经阻滞的起效和持续时间以及术后镇痛效果的影响。方法选取桡骨远端切开复位内固定的患者42例,随机分为罗哌卡因组(R组)和罗哌卡因复合右美托咪定组(RD组),每组21例。在超声引导下行低位肌间沟臂丛神经阻滞,分别比较两组患者感觉阻滞起效时间、运动阻滞起效时间、感觉恢复的时间、运动恢复的时间、伤口开始疼痛的时间、术后视觉模拟疼痛评分(visual analogue scale,VAS)等指标。结果两组感觉和运动阻滞的起效时间差异无统计学意义(P>0.05),RD组的感觉和运动阻滞持续时间明显长于R组(P<0.01),RD组的镇痛时间明显长于R组(P<0.01)。在神经阻滞后30 min和60 min,RD组的HR低于R组(P<0.05),在阻滞后的15、30和60 min,RD组的MAP低于R组(P<0.05),RD组的术后6 h和12 h的VAS评分低于R组(P<0.05)。结论罗哌卡因复合右美托咪定对桡骨远端骨折切开复位内固定的患者行低位肌间沟神经阻滞能延长神经的感觉和运动阻滞持续时间,延长术后镇痛的时间,降低患者术后6 h和12 h的VAS评分。
