Surgical site infections.

This article examines the epidemiology and risk factors for the development of surgical site infections (SSIs), the importance of appropriate administration of prophylactic antibiotics, nonpharmacologic strategies, and the role of new "active" devices in reducing SSIs. A review of the pertinent English-language literature shows that many factors contribute to the risk of a patient developing an SSI. These include the patient's health status, preparation of the patient before surgery, and the use of appropriate antibiotic prophylaxis. Careful preparation of the patient and care after surgery is especially important. The use of new "active" antibacterial devices may reduce risk further. Surgeons can minimize the risk to the patient of the development of SSI through strict adherence to established surgical guidelines for perioperative care.
