Asepsis, Antisepsis and Skin Preparation

Abstract

Surgical site infections (SSIs) are a common cause of nosocomial infections. They account for 10–16% of all nosocomial infections. Approximately two-thirds of SSIs are confined to the incision, whereas the remainder involve organs or the spaces involved in the surgical procedure. SSIs have a significant morbidity and mortality, as well as increased cost and prolonged postoperative stay. SSIs can occur both peri- and postoperatively, and skin is a major potential source of microbial contamination. Therefore, not only is it important to create and maintain a sterile field operatively, but good hand hygiene is an important component of postoperative care. Asepsis is defined as a process or procedure performed under conditions in which bacterial contamination has been minimized.
