Interventional
Description of intervention(s) / exposure
Comparison of intranasal versus intravenous hydromorphone given in the postoperative period. Single-dose to be administered via first route (randomised order) at first onset of pain postoperatively, then single-dose via second route to be administered for pain between 12 and 24 hours later. Fentanyl PCIA for breakthrough pain in between these 2 doses.
