A surgical-site infection is a complication that develops following surgery when the incision site becomes infected. Surgical-site infections cause complications and increased disability when they occur after surgery. Mediastinitis develops as a surgical site infection following cardiac surgery in the mediastinal cavity below the sternum. Several risk factors increase the chance of this condition developing, including obesity in the patient, a long hospitalization prior to the procedure, and a patient with a history of diabetes.
