摘要 目的:探讨全静脉麻醉对患者胰岛素抵抗和胰岛素分泌功能的影响,以及红细胞表面胰岛素受体密度和亲和力在全麻手术患者中的变化。方法:收集我院64例全静脉麻醉手术患者(全麻手术组),病发前无糖尿病病史。正常对照组来自同期门诊体检健康人员,血压、血脂正常,无特殊服药史。两组性别构成比、年龄和体重指数经统计学处理差异无显著性(P>0.05)。手术组内年龄、体重及手术前处理、麻醉时间、术中处理比较差异均无显著性(P>0.05)。观察全麻手术患者稳态模式评估胰岛素抵抗指数(HOMA-IR)、胰岛素分泌指数(HOMA-β)、空腹血糖的变化。放射受体分析测定红细胞表面胰岛素受体密度和亲和力。结果:(1)全麻手术组患者HOMA-IR、胰岛素、空腹血糖含量明显高于正常对照组,HOMA-β明显低于正常对照组(P<0.01)。(2)全麻手术组患者红细胞表面胰岛素受体密度和亲和常数较正常对照组明显减少(P<0.01)。结论:全静脉麻醉手术患者存在胰岛素抵抗。红细胞膜胰岛素高亲和力受体和亲和力降低可能是全麻手术患者发生胰岛素抵抗的重要机制。
