摘要 目的观察左旋布比卡因胸段硬膜外阻滞用于乳癌改良根治术的麻醉效能及不良反应。方法40例行乳癌改良根治术的患者,随机分成两组:对照组使用0.375%布比卡因+0.5%利多卡因连续硬膜外阻滞,试验组使用0.375%左旋布比卡因+0.5%利多卡因连续硬膜外阻滞,每组20例。观察指标包括:SP、DP、MAP、HR、SPO2,感觉阻滞起效时间,最高阻滞平面时间,麻醉维持时间,阻滞范围,麻醉质量,呼吸抑制程度及不良反应。结果两组麻醉起效时间,麻醉维持时间,阻滞范围,麻醉质量无显著性差异(p>O.05),达最高阻滞平面时间试验组快于对照组(p<0.05)。两组呼吸抑制及不良反应发生率差异无显著性(p>0.05)。结论0.375%左旋布比卡因+0.5%利多卡因与0.375%布比卡因+0.5%利多卡因都能安全用于胸段硬膜外阻滞,满足乳癌改良根治术的麻醉要求。鉴于左旋布比卡因较短的诱导时间和较低的神经及心脏毒性,用于胸段硬膜外阻滞具有优越性。
