Both Groups will receive routine postoperative care and identical postoperative analgesic protocols to assess adequacy of postoperative analgesia (see Postoperative Analgesia Protocol and Postoperative Data Sheets). A postoperative analgesic order set will be created specifically for study patients to receive IV acetaminophen every 6 hours for 24 hours. The American Pain Society Outcome Questionnaire (APS-POQ) will be administered to patients prior to discharge (see data sheet).15
