Chlorhexidine–Alcohol versus Povidone–Iodine for Surgical-Site Antisepsis

Abstract
Since the patient's skin is a major source of pathogens that cause surgical-site infection, optimization of preoperative skin antisepsis may decrease postoperative infections. We hypothesized that preoperative skin cleansing with chlorhexidine–alcohol is more protective against infection than is povidone–iodine.
