Prospective randomized controlled trial to determine if opioid-free anesthetic for tonsillectomy is non-inferior to standard opioid-containing anesthetic



Primary: To determine if an opioid-free anesthetic provides equivalent acute postoperative pain relief in tonsillectomy.

Secondary: To determine if post-operative pain at home is not significantly different with an opioid-free regimen compared to an opioid containing regimen for tonsillectomy.

Study Design: Prospective, randomized, multi-center trial study

Study Interventions and Measures:

Subject will be randomized to 1:1 intra-operative opioid-free (OFG) vs traditional care anesthetic with opioids (TCG) group

The primary endpoint is the median pain score (calculated by a blinded validated observer in the recovery room at two time intervals) between the two cohorts.
