1、不同麻醉方式对老年人上腹部手术应激和免疫功能的影响【摘要】目的探讨3种麻醉方式对老年人上腹部手术应激和免疫功能的影响。方法48例择期上腹部手术的老年患者随机分为3组:硬膜外阻滞组(A组)、单纯全麻组(B组)、硬膜外阻滞加全麻组(C组)。分别于不同时间点抽取外周静脉血采用高效液相色谱法测定肾上腺素(E)、去甲肾上腺素(NE)、采用放射免疫分析法测定皮质醇、采用酶联免疫分析法(ELISA)测定白细胞介素-6(IL-6)、白细胞介素-8(IL-8)和肿瘤坏死因子-α(TNF-α)水平。结果麻醉诱导后B、C组皮质醇降低,与诱导前比较差异有显著性意义(P<0.0
2、5);A、B组手术60min至术后3d,皮质醇有不同程度的升高,C组无明显变化;3组E、NE均于手术结束前、术后1d均显著高于诱导前(P<0.01),但C组低于A、B两组(P<0.05或P<0.01);3组患者的血浆TNF-α水平无显著变化,IL-6、IL-8在手术60min、手术结束前均较诱导前显著升高(P<0.05),而A、B组持续时间长至术后3d,C组于术后1d恢复至诱导前水平。结论3种麻醉方法均不能完全阻断手术创伤性刺激导致的应激反应,硬膜外阻滞复合全麻用于老年患者行上腹部手术,应激反应小,全麻药用量小,利于保持各系统功能的稳定和术后镇痛。【关
