E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To compare the effect of intravenous dexamethasone relative to placebo on cumulated postoperative morphine consumption from baseline to 48 hours in hip dysplasia patients undergoing PAO. |
|
E.2.2 | Secondary objectives of the trial |
To compare the effect of repeated doses of intravenous dexamethasone relative to a single dose on cumulated postoperative morphine consumption from baseline to 48 hours in hip dysplasia patients undergoing periacetabulary osteotomy (PAO).
Furthermore, to evaluate postoperative nausea and vomiting and development in inflammatory markers from baseline to 48 hours postoperative.
And, to determine if dexamethasone is superior to placebo for:
- Perception of pain intensity postoperatively and need for supplemental analgesics
- Prevalence and degree of postoperative nausea and vomiting, including antiemetic consumption
- Patient-reported outcome measures (PROMs)
- Perception of sleep quality
- Mobilization postoperatively
- Prevalence and degree of serious adverse events (SAE), e.g. complicating wound infection, which need antibiotic treatment or revision surgery.
