If they meet inclusion criteria and agree, an approved informed consent form (see attached) will be signed. The goal will be to obtain 150 patients. Once the drug bag is received from Pharmacy, it will be infused over 15 minutes, approximately 30 minutes prior to the incision start time. All patients will receive standard preoperative anesthesia and antibiotics per protocol for pain and prevention of surgical site infection.
