Main objective

Scope: Therapy, Safety, Efficacy

The primary objective of this trial is to investigate the efficacy of a single‐dose of Intraoperative methadone, administered after induction of anesthesia, compared to administration of fentanil and oxycodone per-operatively (usual care), on the endpoint postoperative
opioid consumption in adult subjects undergoing elective or subacute CABG and/or valve surgery.

Secondary objectives 1

  1. The secondary objectives of this trial are to investigate the efficacy of the intervention on patient reported outcomes including pain intensity, quality of recovery and patient satisfaction, as well as effect on safety endpoints.

Conditions and MedDRA coding

Following heart surgery, patients experience poor postoperative pain control and a moderate/high opioid consumptions. This is correlated to adverese events and poor outcome.

1 Methadone versus fentanil and oxycodone for post-operative pain reduction
This study is a randomized placebo-controlled, assessor- and participant-blinded trial. The study will be initiated at the tertiary heart center at Copenhagen University hospital, Rigshospitalet. Participants will be randomized in a 1:1 ratio to either methadone or usual care consisting of fentanil and oxycodone.
Randomised Controlled Double [{"id":94007,"code":4,"name":"Analyst"},{"id":94008,"code":5,"name":"Carer"},{"id":94005,"code":2,"name":"Investigator"},{"id":94006,"code":3,"name":"Monitor"},{"id":94004,"code":1,"name":"Subject"}] methadone group: The methadone group will receive a fixed dose of methadone of 0.3mg/kg administered after induction of anesthesia.
usual care group: The usual care group will receive a fentanil 15 mcg/kg at induction of anesthesia plus oxycodone 0.2mg/kg approximately 30 minutes prior to end of surgery.
