Methods Twenty patients were randomly assigned to two groups, 10 cases of operation on vertebral canal, 10 cases of colorectal radical operation.Venous blood was drawn at 1 day before operation, 2, 4, and 6 hours following skin incision, and 1 day after operation, in order to measure serum IL-6, CRP, and cortisol.pHi and plasma lactate were also measured at the same time points.Results Serum concentrations of IL-6 and cortisol increased gradually following operation, reaching the peak value at 6 hours from the beginning of operation.CRP was not detectable until the first day after operation.Peak concentration of IL-6 had positive relationship with CRP.These variables changed more significantly in colorectal group than that in orthopaedic group (P<0.05).pHi decreased gradually, reaching the lowest level at 4 hours from the beginning of operation, and to more extent in colorectal group than that in orthopaedic group (P<0.05).Conclusion IL-6 may reflect tissue damage more sensitively than CRP.Colorectal surgery might induce systemic disorder to more extent, in terms of immuno-endocrinal aspect as well as tissue perfusion, reflected with pHi.展开更多
