Design outcomes

Primary

MeasureTime frame
Primary end point(s): Pain relief over the 24 hour post-operative period Incidence and severity of nausea ;Main Objective: To compare the incidence and severity of nausea in the study treatment groups, during the 18-hour period starting 6 hours after titration to pain relief; following confirmation of the assumption of non-inferiority between the two groups of pain relief over the 24 hours post-operative period. Pain relief and nausea will be determined by measuring the areas under the curves of pain intensity and nausea verbal rating scale scores.; Secondary Objective: To compare the analgesic effect of the study treatments. To compare the incidence and severity of nausea and vomiting in the study treatment groups over the following time periods following achievement of baseline pain relief: 0-12 hours, 0-24 hours, 0-48 hours, 12-24 hours, 24-48 hours. To compare the amounts of study drug required to achieve a baseline pain severity score of = 3. To compare the total consumption of study drugs (loading dose, plus dose to achieve the baseline pain level, plus the amounts given by PCA and PCA rescue. To compare the patients; overall opinions of the study treatments. To compare the safety of the study treatments. To compare the use of anti-emetic medication.
