摘要 目的评价右美托咪定对心肺转流(CPB)下行心脏瓣膜置换术病人围术期炎性因子变化和胰岛素抵抗的影响。方法择期行体外循环心脏瓣膜置换术病人86例,采用随机数字表法分为对照组(C组,n=46)和右美托咪定组(D组,n=46)。D组麻醉诱导后静注右美托咪定,C组静注等量的生理盐水。比较两组麻醉诱导前(T0)及CPB 30 min(T1)、术毕(T2)和术后24h(T3)血清肿瘤坏死因子-α(TNF-α)、白介素-6(IL-6)、白介素-8(IL-8)浓度、胰岛素、血糖水平以及胰岛素敏感度。结果与T0比较,两组T1、T2和T3时期,TNF-α、IL-6和IL-8水平显著升高(P<0.05)。与C组比较,D组T1、T2和T3时TNF-α、IL-6和IL-8水平显著低于C组(P<0.05)。T1、T2时胰岛素和血糖均明显降低(P<0.05),胰岛素敏感指数(ISI)明显升高(P<0.05)。结论右美托咪定可明显减少CPB下心脏瓣膜置换术病人炎性反应,改善胰岛素抵抗。
