Description	The morphine equivalent is a unit of measure to compare the efficacy of different types of opioids (narcotics). The patients were allowed to take additional pain medication in addition to either study drug or placebo. This outcome measure reports the amount of morphine (in mg) equivalent to the amount of concomitant pain medication used by the patient.
Time Frame	24 hours after the end of surgery
