Abstract: Surgical site infection (SSI) is the most common and potentially preventable postoperative complication. It is one of the most frequent nosocomial complications representing about a fie following three factors are the determinants of any infectious process: 1. The infecting organism, 2. The environment in which the infection takes place (the local response), 3. The host defense mechanism, which deals systematically with the infectious process. Taking into account the incidence of surgical site infections and resulting serious health problems the risk of infection needs to by assessed. The risk of infection is associated with the clinical and environmental conditions, and above all with the source of infection. As shown, a frequent source of infection is the normal flora of the patient i.e. Intestinal bacteria in the case of operations on the abdomen and skin flora in the case of cardiac surgery. Measures to reduce the risk of infection include the shortening of the endogenous flora of the patient stay in hospital, prophylactic eradication of MRSA from nasal mucosa of the atria, better personal hygiene before surgery, adequate perioperative prophylaxis and proper care of wounds.
