摘要 目的探讨异丙酚对体外循环肺损伤的作用。方法选择拟行心瓣膜置换术的患者30例,随机分为两组,每组各15例。异丙酚组麻醉维持持续输注异丙酚(8mg·kg-1.h-1),对照组麻醉维持用芬太尼和咪唑安定。体外循环(CPB)开始前、主动脉开放后5min及CPB结束时取左右心房血液,光学显微镜下检测中性粒细胞数;同时取适量动脉血,测定细胞因子IL-6、IL-8、IL-10和TNF-α浓度。测定两组围术期肺动态顺应性和氧合指数。结果两组转流前左、右心房PMN无显著差异,CPB后两组中性粒细胞计数比CPB前显著升高(p<0.01),对照组主动脉开放后5min及CPB后左心房中性粒细胞计数显著低于右心房(P<0.01或P<0.05),而异丙酚组左心房高于右心房(P<0.05)。CPB后两组IL-6,IL-8,TNF-α进行性增高(P<0.05或0.01),异丙酚组与对照组相比明显减少IL-6,IL-8,TNF-α,有统计学意义(P<0.05或0.01)。IL-10在对照组和异丙酚组均进行性增高,两组比较无统计学意义(P>0.05)。两组患者CPB后肺顺应性及氧合指数显著降低(P<0.05或0.01),CPB后1h最低,6h后有所改善,异丙酚组在各时间点肺顺应性及氧合指数均显著高于对照组(P<0.05或0.01)。结论异丙酚对体外循环肺损伤有保护作用。
