Clinical Trial 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.


Clinical Trial Description

Patients between 6 months and 18 years undergoing T&A surgical procedures will be reviewed for potential study enrollment. If participants agree to participate, they will be randomized into one of the three groups: - the suprazygomatic maxillary nerve (SZMN) block treatment cohort - the SZMN block with Dexmedetomidine treatment cohort - the control cohort (standard of care). After anesthesia induction, patients randomized into the SZMN-treatment group or SZMN+Dexmedetomidine treatment group will receive bilateral single injection SZMN blocks under general anesthesia in the operating room. Participants enrolled into the control group will receive the standard of care with no changes to their anesthetic or surgical care. This group will not receive the SZMN block. Postoperative pain scores and opioid consumption for all three groups will be collected in the PACU and for each postoperative day for a total of 14 postoperative days. We will also collect the following data: time to discharge readiness, postoperative nausea/vomiting, emergence delirium, oxygen desaturation and respiratory events, ability to tolerate oral intake, bleeding, hospital readmission, and adverse events related to the nerve block. ;
