The goal of this clinic trial is to evaluate the impact of dexmedetomidine as an adjunct pain pain medication on opioid-free recovery in children undergoing adenotonsillectomy with Suprazygomatic maxillary nerve block (SZMB). The main questions it aims to answer are:
* Does SZMB with the local anesthetic ropivacaine and the adjuvant dexmedetomidine result in less pain
* Is dexmedetomidine associated with an improved quality of recovery at home Researchers will compare pain in participants given an SZMB with ropivacaine and an adjuvant dexmedetomidine, participants given SZMB with ropivacaine only, and a SZMB with ropivacaine and dexmedetomidine given intravenously.
Participants will:
* Be given the SZMB during the surgery.
* Be evaluated after surgery to measure their opioid consumption, pain severity, level of agitation, and level of delirium
* Complete a daily questionnaire for 7 days after surgery on the patients pain and recovery
