AbstractCoronary artery bypass grafting with cardiopulmonary bypass can induce systemic inflammatory response syndrome. To assess the prevalence of preoperative antithrombin and protein C deficiencies in relation to the incidence of this syndrome, antithrombin and protein C levels were measured in 130 patients undergoing coronary artery bypass grafting with cardiopulmonary bypass. Systemic inflammatory response syndrome developed in 36 (27.7%) patients who were predominantly male, had a lower EuroSCORE, longer cardiopulmonary bypass time, higher pre-bypass temperature, and shorter activated coagulation time. Logistic regression showed that predictive factors included bypass duration and pre-bypass temperature; however, low antithrombin levels appeared to be a negative predictive factor. Antithrombin levels were < 80% in 33.8% of patients, and 11.6% had protein C levels < 80%. Postoperative antithrombin and protein C deficiencies are not uncommon in adults undergoing cardiac surgery with cardiopulmonary bypass, but detection of these deficits did not identify patients at increased risk of systemic inflammatory response syndrome.
