摘要 目的研究不同麻醉方法对上腹部手术围术期胰岛素抵抗(insulin resistance,IR)的影响,并在细胞因子水平上探究围术期发生IR的机制。方法择期胆囊切除术患者36例,ASAⅠ~Ⅱ级,随机分为硬膜外麻醉组(E组)和全麻组(G组),各组18例,分别在患者麻醉前、麻醉后、进腹探查胆囊时和术后1h采血,测定血糖、血清胰岛素(insulin,Ins)、脂联素(adiponection,Adi)、抵抗素(resistin,Res)和C-反应蛋白(C-reactive protein,CRP),计算胰岛素敏感性(insulin sensitivity,SI)。结果麻醉前两组各指标差异无显著性。E组仅在麻醉后有Ins显著上升(P<0.01),但在实验观察时间内未发生明显IR。G组全麻诱导插管后血清Ins和CRP明显上升((P<0.05,P<0.01),SI显著下降(P<0.01),发生了明显的IR。G组在麻醉后各时点血清脂联素浓度均显著降低(P<0.01),E组患者血清脂联素水平在麻醉后稍有下降,无统计学意义,但各时点血清脂联素水平明显高于G组(P<0.01)。两组抵抗素水平在实验观察时间内无显著变化。结论上腹部手术围手术期G组发生了显著的IR,发生IR的原因可能与患者血清脂联素的水平下降以及CRP浓度的升高有关。抵抗素可能并没有参与外科性IR。硬膜外麻醉可以显著改善外科IR。
