It prevents transmission of infection, sharps injury and maintains sterility. Wearing a colored surgical glove beneath a standard pair of surgical gloves can be seen more easily if there is a perforation.

Attempting to isolate the skin from the surgical wound is of no benefit and may create increased moisture and bacterial growth under adhesive drapes
