不同麻醉方法对食管癌围术期T淋巴细胞亚群的影响

目的 探讨不同麻醉方法对食管癌患者围术期T淋巴细胞亚群的影响.方法 40例择期食管癌根治术患者,随机分为两组,Ⅰ组为全身麻醉组,Ⅱ组为硬膜外阻滞复合全身麻醉组,每组20例.两组分别于麻醉前(T1)、麻醉后(T2)、术毕(T3)、术后1 d(T4)、术后3 d(T5)测外围血T淋巴细胞亚群的变化.结果 两组患者麻醉后CD3、CD4、CD8、CD4/CD8均下降.术后3 d,Ⅰ组CD3(54.85±6.20)%、CD4(35.50±5.65)%、CD8(22.15±1.13)%、CD4/CD8(1.45±0.25);Ⅱ组CD3(61.86 4-4.25)%、CD4(40.85±4.65)%、CD8(20.05±1.14)%、CD4/CD8(1.60±0.15).Ⅱ组指标恢复,与Ⅰ组比较差异有统计学意义.结论 硬膜外阻滞复合全身麻醉能减轻围术期的应激及麻醉药物对T淋巴细胞亚群的抑制,有利于胸科肿瘤患者的免疫功能的及早恢复.

Effects of different anesthetic techniques on perioperative changes in T-lymphocyte subsets in patients with esophageal carcinoma

Objective To determine the effects of different anesthetic techniques on T-lymphocyte subsets in patients with esophageal carcinoma. Methods Forty patients were randomly assigned into general anesthesia group (group Ⅰ),or combined generae anesthesia with epidural anesthesia group(group Ⅱ). Peripheral blood CD3, CD4,CD8 were measured before induction ( T1 ), after anesthesia ( T2 ), end of operation ( T3 ), 1d ( T4 ), 3d ( T5 ) after surgery. Resolts CD3,CD4,CD8,CD4/CD8 decreased at T2 in the two groups. In group Ⅱ ,CD3,CD4,CD8,CD4/CD8 ratio almost returned to the baseline values at T4 ,while group Ⅰ did not. Conclusion Epidural anesthesia combined with general anesthesia can reduce depression of T-lymphocyte subsets induced by surgical trauma and anesthesia, and is the anesthetic tecnique of choice for cancer patients undergoing major operation.
