Does Pre & Postoperative Dextromethorphan Reduce Post-tonsillectomy Pain

Status Completed

Clinical Trial Summary

With Institutional ethics board and Health Canada approval, pediatric patients (ages 3-12) undergoing tonsillectomy or adenotonsillectomy (under standardized anesthesia) will be randomized to receive dextromethorphan hydrobromide (1mg/kg orally) 30 min preoperatively and again 8 hours postoperatively OR placebo (syrup identical in taste, appearance and volume) at the same time points. The primary outcome is an integrated assessment of perioperative pain scores and opioid use for 24 hours postoperatively. Secondary outcomes include nausea, vomiting, respiratory depression, and bleeding for 24 hours postoperatively. Our hypothesis is that dextromethorphan will decrease the incidence/severity of post-tonsillectomy pain. The improved pain control will be apparent through reduced opioid consumption and integrated pain scores. This will result in a reduced incidence of opioid-related side effects and adverse events.

Clinical Trial Description

With Institutional ethics board and Health Canada approval and parental consent and child assent, pediatric patients (ages 3-12) undergoing tonsillectomy or adenotonsillectomy (under standardized anesthesia) will be randomized to receive dextromethorphan hydrobromide (1mg/kg orally) 30 min preoperatively and again 8 hours postoperatively OR placebo (syrup identical in taste, appearance and volume) at the same time points. The primary outcome is an integrated assessment of perioperative pain scores and opioid use for 24 hours postoperatively. Pain scores were collected preoperatively at rest and then at 1,2,3,8,9,10 and 24 hours postoperatively using the validated Children's Hospital of Eastern Ontario Pain Scale (CHEOPS). Secondary outcomes include nausea, vomiting, respiratory depression, and bleeding recorded by blinded observers for 24 hours postoperatively.

Our hypothesis is that dextromethorphan will decrease the incidence/severity of post-tonsillectomy pain. The improved pain control will be apparent through reduced opioid consumption and integrated pain scores. This will result in a reduced incidence of opioid-related side effects and adverse events. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
