Objective To observe the effects of flurbiprofen axetil postoperative patient-controlled intravenous analgesia (PCIA) on stress response in patients undergoing gynecological laparoscopy operation.Methods One hundred and twenty ASA Ⅰ - Ⅱ gynecological laparoscopy operation patients were randomized to two groups, 60 cases in each group.Group F received flurbiprofen axetil 4 mg/kg while group S were given sufentanil 1.5μ g/kg for postoperative PCIA.Tumor necrosis factor-α (TNF-α ) and interleukin (IL)-6, IL-8, IL- 10 were estimated preoperative(T_0), operation termination(T_1) and 48 h after operation(T_2).Results VAS scores were less than 4 scores and no significant difference between two groups.There was no significant difference in TNF- α intraclass and interclass between two groups(P > 0.05 ).IL-6, IL-8, IL- 10 in two groups were significantly higher at T_1 and T_2 than those at To (P< 0.05).IL-6, IL-8 at T_1 and T_2 were lower in group F than those in group S [T_1 and T_2: IL-6 was ( 18.39 ± 3.01 ), ( 13.43 ± 3.11 ) ng/L, IL-8 was (24.25 ± 2.75 ), ( 15.31 ± 2.65 ) ng/L in group F; IL-6 was (38.02 ± 2.95 ), (23.28 ± 2.43 ) ng/L, IL-8 was ( 37.56 ± 2.97 ), ( 24.86 ± 3.11 ) ng/L in group S]( P < 0.05 ).While IL- 10 was significantly higher and lasted longer in group F than that in group S [(26.72±4.41), (21.03±2.99) ng/L in group F; (22.18 ± 3.21), (16.89 ± 4.48) ng/L in group S](P < 0.05).Conclusion PCIA with flurbiprofen axetil in gynecological laparoscopy operation patients can alleviate inflammatory response.
