Abstract

Objective To observe the effects of different anesthetic techniques on T-lymphocyte subsets in patients with cardia cancer. Methods Thirty-two patients undergoing elective radical operation for cardia cancer who had been average assigned into two groups by random digits table, group Ⅰ :general anesthesia;group Ⅱ :epidural anesthesia combined with general anesthesia (16 cases in each group).Peripheral blood T-lymphocyte subsets were measured before induction, after anesthesia, end of operation, 1d,3 d after operation. Results CD3,CD4,CD8 and CD4/CD8 all decreased in two groups after anesthesia,end of operation and 1 d after operation than before induction (P 0.05),while in group Ⅰ still lower [(55.83 ±5.20)%, (35.15 ±5.65)%, (23.00 ±1.03 )%, 1.47 ± 0.35 ](P< 0.05 ). The two groups ontrast had significant deviation at 3 d after operation (P<0.05). Conclusion Epidural anesthesia combined with general anesthesia can reduce depression of Tlymphocyte subsets induced by surgical trauma and anesthesia. Key words: Stomach neoplasms; Anesthesia,epidural; T-lymphocyte subsets
