The factors effecting complement activation in open heart surgery.
The activation of the complement system was investigated in 10 patients with rheumatic valve disease having heart surgery. The C3c, C4, leukocyte count and polymorphonuclear neutrophil count were determined in the blood samples taken before anaesthesia, after anaesthesia, 10 minutes after protamine administration and after the closure of the skin incision. In addition, atrial blood samples were taken after the release of the cross-clamp and pulmonary neutrophil trapping was investigated. In this study C3c and C4 consumption was found to take place after 30 minutes of CPB (cardiopulmonary bypass) and 10 minutes after protamine administration; the affects of anaesthesia and heparin were not significant.
