AimPostoperative wound infections generally cause considerable extra morbidity, mortality and costs. The prevalence of total wound infections after cardiac surgery, including both sternal wound and donor site infections, ranges from 1.3 to 12.8%. The present study was conducted to identify the incidence of wound infections following cardiac surgery, to identify the risk factors and evaluate the efficacy of present modes of management.MethodsFrom September 2004 to May 2005, 493 consecutive patients undergoing cardiac surgery were included in the study and were followed for the prevalence of surgical site infection (SSI) up to 60 days postoperatively. The wound infections were defined according to the Centers for Disease Control and Prevention (CDC) and U.S. National Nosocomial Infections Surveillance (NNIS) system criteria.ResultsThe total incidence of SSI was 3.9%. Sternal wound infection (SWI) occurred in 17 patients (3.4%). Superficial wound infection was diagnosed in 10 patients (2%) and deep wound infection in 7 patients (1.4%). Donor site infection (DSI) occurred in 2 patients (0.4%). Early reoperation for bleeding, postoperative dialysis and the use of one internal mammary artery were independently associated with an increased risk of SWI.ConclusionPreventing SSI in the operating room is the primary goal of the surgical team. Attention should be paid to antibiotic prophylaxis and Methicillin-resistant Staphylococcus aureus (MRSA) nasal carriage treatment. The identification of risk factors will help to further reduce the incidence of wound infection.
