- Changes in Postoperative Pain Scores [ Time Frame: preoperatively (baseline), post-anesthesia care unit (PACU or recovery room) arrival (2-3 hour), and 6,12, 18, and 24 hours following the initial administration of the study drug ]To compare analgesic efficacy as measured by changes in postoperative pain scores assessed preoperatively, at 6, 12, 18, and 24 hours following the initial administration of the study drug. Pain scores are assessed on a scale of 0 - 10. 0 = No Pain; 10 = Worst Possible Pain
- Pain Medication Consumption Rates [ Time Frame: Arrival to post-anesthesia care unit (PACU or recovery room) (2-3 hours post baseline) to 24 hours post administration of study drug ]Number of participants who required rescue pain medication. Rescue pain medications is defined as administration of pain medication in excess of standard postoperative pain medication orders.
- Average Length of Stay (LOS) [ Time Frame: Baseline to discharge (1-4 days) ]To compare patient length of stay (LOS) between groups as measured by day of discharge minus day of admission.
