Brain Activity and Anxiety in Children Aged 2 to 8 Undergoing Eye Surgery with General Anesthesia to Study Emergence Delirium

What this Trial Is About

Researchers are investigating the relationship between preoperative anxiety and emergence delirium in children aged 2 to 8 undergoing eye surgery under general anesthesia. The study focuses on whether brain activity patterns, specifically EEG frontal alpha asymmetry, play a role in this connection. The goal is to better understand how anxiety before surgery may influence delirium after waking from anesthesia in pediatric patients. Participants will undergo standard ophthalmic surgery with general anesthesia as part of their treatment. The study groups include children who develop emergence delirium and those who do not, with delirium assessed every 10 minutes during their stay in the post-anesthetic care unit PACU using the Pediatric Assessment of Emergence Delirium PAED scale. During the study, childrens anxiety levels before surgery will be measured using the modified Yale Preoperative Anxiety Scale mYPAS, and brain activity will be recorded to analyze EEG frontal alpha asymmetry. Emergence delirium will be closely monitored post-surgery in the PACU. Researchers will evaluate peak PAED scores to understand the relationship between anxiety, brain activity, and delirium. The study is expected to be completed by the end of 2026.
