Brief summary
Prospective randomized controlled trial to determine if opioid-free anesthetic for tonsillectomy is non-inferior to standard opioid-containing anesthetic
Detailed description
Objectives: 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.
Interventions
Ketorolac (0.5mg/kg; maximum 15mg intravenously) will be given at end of procedure after evaluation for hemostasis.
Dexmedetomidine (1ug/kg with maximum 50ug intravenously) will be given at beginning of procedure.
Morphine (0.05-0.1 mg/kg intravenously) will be given intra-operatively per institutional standard clinical care.
Fentanyl (0.5-2 ug/kg intravenously) will be given intra-operatively per institutional standard clinical care.

Masking description
The unblinded members are the treating anesthesiologist for the case, staff who randomize, and collect and enter intra-op medications into electronic data capture (EDC). Blinded members include the subject/family members, the surgeon, staff who perform post-op assessment, physician investigator who perform any adverse event/serious adverse event (AE/SAE) assessments, statistician and data safety monitoring board (DSMB).

Primary
| Measure | Time frame | Description |
|---|---|---|
| Mean FLACC (Face, Legs, Activity, Cry, Consolability) Pain Score | up to 1 hour | Mean FLACC pain assessment scores are calculated 15 and 30 minutes after awakening, Scores are calculated by a blinded study team observer. Minimum Score: 0 and Maximum Score: 10. Higher scores indicate worse outcomes. One Nursing Maximum FLACC pain score is obtained by an unblinded patient Registered Nurse (RN) during the patient's Post-Anesthesia Care Unit (PACU) stay within one hour of awakening. The pain score is collected from the nursing documentation in the electronic medical record. FLACC Minimum Score: 0 and Maximum Score: 10 Higher scores indicate worse outcomes. |
