ClinConnect Summary

This clinical trial is looking at two different ways to give anesthesia to children undergoing eye surgery for strabismus, a condition where the eyes do not properly align. The study aims to compare the effectiveness of two local anesthesia techniques—peribulbar block and subtenon block—alongside general anesthesia. Researchers want to see how these methods affect the oculocardiac reflex, which is a response that can happen during eye surgery, as well as how well pain is managed after the surgery and the occurrence of vomiting afterward.

The trial is open to children aged 6 to 13 years who are generally healthy and scheduled for this type of surgery. However, children with specific eye problems, certain health conditions, or allergies to anesthesia medications cannot participate. If enrolled, participants can expect to receive one of the anesthesia techniques during their surgery and will be monitored closely for any side effects. This study will help doctors understand the best ways to manage anesthesia for kids undergoing eye surgery.
