Investigating the link between preoperative anxiety and emergence delirium in children

Official title: Mediation Role of Perioperative Electroencephalogram Frontal Alpha Asymmetry to Pediatric Emergence Delirium

Run by Gangnam Severance Hospital · NCT05800639 · Data updated 2026-11-12

This study is trying to see if kids aged 2-8 who feel anxious before eye surgery are more likely to experience confusion as they wake up from anesthesia.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are children aged 2-8 years scheduled for elective ophthalmic surgery requiring general anesthesia.

Probably not a fit

Patients who may not benefit from this study include those undergoing emergency surgery or those with developmental delays or psychiatric conditions.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study examines the relationship between preoperative anxiety levels and emergence delirium in pediatric patients undergoing elective ophthalmic surgery under general anesthesia. The researchers hypothesize that EEG frontal alpha asymmetry plays a significant role in this association. They will utilize the modified Yale Preoperative Anxiety Scale (mYPAS) to assess anxiety and the Pediatric Assessment of Emergence Delirium (PAED) scale to evaluate emergence delirium. Mediation analysis will be conducted to explore these relationships in children aged 2-8 years.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of emergence delirium in pediatric patients, enhancing their surgical experience.

How similar studies have gone: While the specific approach of examining EEG frontal alpha asymmetry in this context may be novel, studies on emergence delirium and preoperative anxiety have shown varying degrees of success.
