A 73-year-old man has ischemic rest pain of the left calf. Workup reveals occlusion of the left superficial femoral artery. He is scheduled for an elective femoral-popliteal bypass. A good way to reduce the risk of infection would be to:

Irrigate the wound with bacitracin during the operation

Start cefazolin 1 gIV 4 hours before the surgery

Use a plastic adherent drape

Not shave the leg

Question Category:

Correct Answer:

Not shave the leg

Description:

Shaving is associated with an increased incidence of wound infection compared to the use of electric clippers or depilatories, as well as compared to no hair removal at all. Prophylactic antibiotics should be started within 60 minutes of the incision time. Plastic adherent drapes and antibiotic wound irrigation have not been proven to reduce wound infection rates. Wound infection rates increase as duration of surgery increases beyond 2 hours due to the reemergence of skin flora.
