Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Morphine | Analgesia with equipotent doses of Morphine and Hydromorphone will be administered in titrated doses. Doses are 1ml=1mg of morphine or 0.2 mg of hydromorphone. Potency ratio of 1:5 (M: HM).~0.05mg/kg morphine units (rounding off to the nearest 1 ml or 0.5 ml)~Morphine: Participant to be asked for their pain score, and if it is more than 4 out of 10 (NAS): to receive the 1st dose within 5 minutes after coming to PACU: 0.04mg/kg morphine units (rounding off to the nearest 1 ml or 0.5 ml); with a maximum of 3 mg of morphine equivalents. Repeat doses: 0.02 mg/kg morphine units every 5-10 minutes to titrate for analgesia and side effects (rounding off to the nearest 1 ml or 0.5 ml) | 11 | 199 | EG000 |
| Group 2 | Hydromorphone | Analgesia with equipotent doses of Morphine and Hydromorphone will be administered in titrated doses. Doses are 1ml=1mg of morphine or 0.2 mg of hydromorphone. Potency ratio of 1:5 (M: HM).~0.05mg/kg morphine units (rounding off to the nearest 1 ml or 0.5 ml)~Hydromorphone: Participant to be asked for their pain score, and if it is more than 4 out of 10 (NAS): to receive the 1st dose within 5 minutes after coming to PACU: 0.04mg/kg morphine units (rounding off to the nearest 1 ml or 0.5 ml); with a maximum of 3 mg of morphine equivalents. Repeat doses: 0.02 mg/kg morphine units every 5-10 minutes to titrate for analgesia and side effects (rounding off to the nearest 1 ml or 0.5 ml) | 10 | 202 | EG001 |
