Summary

This study tests whether a lower dose (6%) or a higher dose (8%) of sevoflurane gas works better and causes fewer side effects when putting children aged 1 to 6 years to sleep for minor eye surgery. The main goal is to see which dose leads to less agitation and confusion when the child wakes up. The trial involves 80 children and will also measure how fast they fall asleep and recover.
