Thoracicparavertebralregionalanesthesiaforpainreliefinpatientswithbreastcancersurgery
背景与目的
本研究的目的是评估乳腺癌手术患者行胸椎旁神经阻滞麻醉(TPVBRA)的有效性和安全性。
方法
将72例乳腺癌手术患者随机分为干预组和对照组,每组36例。两组均接受20ml0.25%布比卡因行TPVBRA。此外,干预组受试者还接受了1mg/kg右美托咪啶。评估心率(HR)、收缩压(SBP)、舒张压(DBP)、疼痛强度(视觉模拟评分法、VAS)和镇痛消耗量,并记录不良事件。
结果
在手术开始后30分钟,2组之间的HR(P<0.05)、SBP(P<0.05),DBP(P<0.05)存在明显差异。此外,干预组比对照组的首次使用镇痛药物的时间更长(P=0.),而且镇痛药物的平均消耗量也更少(P=0.)。然而,在任何时间点,HR和VAS在两组之间无统计学差异(P>0.05)。此外,两组不良反应发生情况相似(P>0.05)。
结论
这项研究的结果表明,联合布比卡因和右美托咪定进行TPVBRA能够提高镇痛的时间和质量,同时没有严重不良事件的发生。
