Reduction of the risk of perioperative transmission of bloodborne infe
ction may be accomplished by barrier precautions, changes in surgical
technique, and appropriate HIV testing. Prevention of mucocutaneous an
d parenteral exposure of both patients and health-care workers to body
fluids is a basic principle. Preoperative HIV testing has no role to
play in the emergency surgical patient. Re-engineering needle use has
the potential to reduce significantly the risk of parenteral exposure
to blood.
