Abstract
Objective To explore the trend of variation and relationship of postoperative pain and serum complement C 3 and C4 in cancer patients undergoing rectum surgery .Methods 100 patients ,who were scheduled for rectum carcinoma surgery ,were se-lected to the study .Pain was assessed by a visual analog scale at 12 h before operation and 4 ,8 ,12 ,24 ,48 ,72 ,120 h after surgery . The blood samples were obtained at the same time .The contents of serum complement C3 and C4 were determined by immunoturbi-dimetry .Results The VAS values in 4 ,8 ,12 ,24 ,48 ,72 h post-operation were significantly higher than 12 h pre-operation(P<0 .01) ,and in 120 h post-operation returned to 12 h pre-operation level .Compared with 12 h pre-operation ,the contents of serum complement C3 and C4 in 4 ,8 ,12 ,24 ,48 h post-operation were significantly decreased (P<0 .01) .The contents of serum comple-ment C3 and C4 returned to 12 h pre-operation level in 72 h post-operation .The results of correlative study on VAS values and the contents of serum complement C3 showed a negative correlation(r= -0 .622 ,P<0 .01) .The results of correlative study on VAS values and the contents of serum complement C4 also showed a negative correlation(r= -0 .649 ,P<0 .01) .Conclusion Postoper-ative pain can induce complement activation ,reduce the levels of serum complement C3 and C4 ,and inhibit immunoreactions .关键词
