Bands in Peripheral Blood After Coronary Artery Bypass Grafting With and Without Cardiopulmonary Bypass

Coronary artery bypass graft (CABG) surgery is associated with reperfusion syndrome and activation of inflammatory reaction (SIRS). These are more exaggerated when cardiopulmonary bypass (CPB) is used. The aim of the study is to compare signs of SIRS (heart rate, tachypnea or hypocarbia, leukocytosis, hyperpyrexia or hypothermia) and the granulocytes subsets in peripheral blood from patients who underwent CABG surgery with or without use of CPB. The researchers expect significant differences in SIRS criteria between both groups. If the differences will occur significant, the parameter may be used as candidate variable for a complications prediction model after CABG surgery.
