ObjectiveTo investigate the effects of ulinastatin (UTI) on cerebral inflammatory response during cardiopulmonary bypass (CPB).MethodsTwenty-four NYHA II-III patients (13 males and 11 females) aged 23-45 years, undergoing elective cardiac valve replacement under hypothermic CPB were randomly divided into 2 groups: ulinastatin group (Group U, n=12) and control group (Group C, n=12). In group U, UTI (1.2 x 10(4) U/kg) was given intravenously after the induction of anesthesia, 0.6 x 10(4) U/kg UTI was added to the priming solution, and 0.6 x 10(4) U/kg UTI was given about 5 min before the aortic decamping. In Group C, normal saline was given instead of UTI. Internal jugular vein was cannulated and the catheter was advanced retrogradely till jugular bulb. Blood samples were taken simultaneously from artery and jugular bulb after induction of anesthesia (T1), 60 min (T2) and 6 h (T3) after discontinuation of CPB for determination of TNFalpha, IL-6, IL-8 and IL-10. The juguloarterial gradients of these cytokines (deltaTNFalpha, deltaIL-6, deltaIL-8, and deltaIL-10) were calculated.ResultsIn Group C, arterial levels of TNFalpha, IL-6, IL-8, IL-10 at T2 and T3, deltaTNFalpha, deltaIL-8 and deltaIL-10 at T2, deltaTNFalpha, deltaIL-6 and deltaIL-10 at T3 significantly increased (P < 0.01). deltaIL-8 increased at T3 (P < 0.05). In Group U, arterial levels of IL-6, IL-8, IL-10 at T2, arterial levels of IL-6, IL-8,IL-L-10 and deltaTNFalpha, deltaIL-8 at T3 significantly increased (P < 0.01). Arterial levels of TNFalpha at T2 and T3, deltaTNFalpha, deltaIL-10 at T2, deltaIL-6 at T3 increased (P < 0.05). Arterial levels of TNFalpha, IL-6 and deltaTNFalpha, deltaIL-8 at T2, arterial levels of TNFalpha and deltaIL-6 at T3 in Group U were lower than those in Group C (P < 0.05). Arterial levels of IL-6 at T3, IL-8 at T2 and T3 in Group U were significantly lower than those in Group C (P < 0.01). Arterial levels of IL-10 and deltaIL-10 at T3 in Group U were higher than those in Group C (P < 0.05).ConclusionSystemic and cerebral activation of inflammatory response during CPB can be alleviated by ulinastatin.
