Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional trial in pediatric patients with sleep-disordered breathing will compare suprazygomatic maxillary nerve block using bupivacaine to a placebo, administered during coblation intracapsular tonsillectomy or adenotonsillectomy. The goal is to determine if the block lowers postoperative pain and improves recovery. Eligible participants are children aged 3 to 9 whose guardians can consent and who meet safety criteria; exclusions include allergies to local anesthetics, coagulopathy, certain congenital facial conditions, developmental disorders, and airway difficulties. The study is conducted at London Health Sciences Centre and associated institutions in London, Ontario.
