摘要 目的研究低浓度小剂量罗哌卡因在静脉局部麻醉的临床应用。方法60例手外科患者随机分成两组:R1组为0.125%罗哌卡因40 mL;R2组为0.2%罗哌卡因40 mL。记录HR、MAP、R、SpO2、感觉及运动阻滞时间、VAS评分、Bromage评分、Ramsay评分、局麻药不良反应、术后镇痛时间及镇痛药用量。结果两组患者静脉注射麻醉药后感觉神经阻滞时间无统计学差异(P>0.05);松止血带后痛觉出现时间R1组明显短于R2组,两组之间有统计学差异(P<0.05);R1组运动神经未阻滞无法计时,松止血带后R1组运动神经未阻滞无法计恢复时间,运动阻滞及恢复时间两组间有统计学差异(P<0.05)。两组患者术中、术后VAS评分及Ramsay评分均无统计学差异(P>0.05);术中Bromage评分R1组明显高于R2组,两组间有统计学差异(P<0.05);术后Bromage评分组间均无统计学差异(P>0.05)。局麻药不良反应R1组一过性心动过缓明显少于R2组,两组间有统计学差异(P<0.05);头晕、耳鸣、低血压、恶心呕吐、心律失常、呼吸抑制、意识消失、Q-T延长等不良反应两组间无统计学差异(P>0.05)。两组术后需止痛药时间有统计学差异(P<0.05),R1组明显短于R2组;术后24 h追加止痛药次数(每次曲马多100 mg肌肉注射)两组间有统计学差异(P<0.05),R1组多于R2组。结论0.125%罗哌卡因40 mL静脉局部麻醉安全有效,不良反应少,可以推广应用。
