RESUMO
Objective:Investigate whether adenosine disodium triphosphate for injection can reduce the systemic inflammatory response which induced by cardiopulmonary bypass.Methods:Forty-seven patients scheduled for cardiac surgery over 30 min following CPB were randomly divided into two groups. In treated group(n=23),adenosine disodium triphosphate for injection(2 mmol/L) was added into the prime during CPB, but in control group(n=24), no adenosine disodium triphosphate for injection was added. Blood samples were drawn from the radial artery at the following time points:(1)before CPB;(2)30 min after aortic clamping;(3)30 min after aortic declamping;(4) 12 h after aortic declamping;(5)24 h after aortic declamping.Enzyme-linked immunosorbent assays(ELISA) were used to measure the concentration of tumor necrosis factor-?(TNF-?), interleukin-6(IL-6), in plasma,CK-MB in plasma level were measured too.Results:The concentration of TNF-??IL-6?CK-MB levels in plasma level of two groups showed no difference before CPB. They all had increased by 30 min after aortic clamping(P
