Clinical Trial Summary

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

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Median Maximum Pain Score	Median Maximum Pain Score by investigational group in the recovery room, calculated by the blinded observer 15 and 30 minutes after awakening.	up to 30 minutes
Secondary	Frequency of nausea, vomiting, pruritis	Collected in recovery room and asked in questionnaires, collected from parents on post-operative days 1, 5, and 30.	up to post-op day 30
Secondary	Frequency of readmission and of seeking unplanned medical attention (phone calls, office visits, ED visits)	Chart review and questionnaires for readmission and medical reattendance, including calls to physician	up to 2 years
Secondary	Frequency of non-artifactual percentage of oxygen saturation (SpO2)<90% (>30 seconds)	Collected in recovery room and chart review	up to 2 years
Secondary	Percentage of patients receiving rescue opioids	Questionnaires and chart review	up to 2 years
Secondary	Family satisfaction with patient recovery based on seven-point Likert score	Follow-up questionnaire to family on post-op days 1, 5, and 30. Parents will be asked to rank how satisfied they are with their child's recovery by using these two prompts: "I am satisfied with my child's recovery," and "I am satisfied with my child's pain control at home." They will choose from the following options: "Strongly agree = 1", "Agree = 2", "More or Less agree = 3", "Undecided = 4", "More or Less disagree = 5", "Disagree = 6", "Strongly Disagree =7." Minimum score is 1, Max is 7. Higher scores indicate worse outcomes.	up to post-op day 30
Secondary	Bleeding prevalence	Follow-up questionnaires and chart review	up to 2 years
