ClinConnect Summary

This clinical trial is studying a method called the suprazygomatic maxillary nerve block (SMNB) in young children who are having surgery for a condition known as cleft palate. The purpose of the trial is to see how effectively a local anesthetic spreads to numb the area around the maxillary nerve, which is important for managing pain after surgery. To do this, researchers will use a special imaging technique called MRI to visualize where the anesthetic goes after it is injected.

To participate in this trial, children need to be between 10 to 24 months old and scheduled for cleft palate surgery. Their overall health should be good, meaning they fall into a category that indicates they are not seriously ill. Parents or guardians must provide written consent for their child to join the study. Participants will receive the nerve block as part of their pain management during the surgery, and the study will help doctors learn more about the best ways to manage pain in children after such procedures.
