Dexmedetomidine Use in SZMN Blocks for Pediatric T&A Pain Control

NCT05208892 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 114

Last updated 2026-03-10

No results posted yet for this study

Summary

The suprazygomatic maxillary nerve (SZMN) block is a well-established, safe and effective regional technique for pain management following cleft palate procedures. However, it has not been studied for patients undergoing tonsillectomy and adenoidectomy (T\&A) procedures. The goal of this study is to determine whether the SZMN block can be utilized to improve pain control and decrease morbidity in pediatric patients undergoing T\&A. An additional goal will be to determine whether the use of dexmedetomidine as a local anesthetic adjunct can prolong the analgesic effects of the SZMN block to cover the entire duration of pain experienced.
