An observational study in Emergence Delirium, sponsored by Gangnam Severance Hospital. Recruiting at 1 site in South Korea. Open to participants aged 2 Years to 8 Years. Per ClinicalTrials.gov, last updated 2026-07-06.
Sponsored by Gangnam Severance Hospital · Observational
This study aimed to investigate whether the association between the preoperative anxiety level and emergence delirium involves EEG frontal alpha asymmetry in pediatric patients undergoing ophthalmic surgery under general anesthesia. The investigators hypothesized that EEG frontal alpha asymmetry contributes a significant portion of the preoperative anxiety - emergence delirium association in pediatric patients. Mediation analysis will be performed to estimate the relationships between preoperative anxiety of children (modified Yale Preoperative Anxiety Scale (mYPAS)), EEG frontal alpha asymmetry, and emergence delirium (Pediatric Assessment of Emergence Delirium (PAED) scale).
Children aged 2-8 year with an American Society of Anesthesiologists (ASA) physical status of I-II who are undergoing elective ophthalmological requiring general anesthesia in Gangnam Severance Hospital will be eligible.
Exclusion Criteria:
Pediatric patients who develop emergence delirium in the post-anesthetic care unit (PACU). Emergence delirium will be assessed using the Pediatric Assessment of Emergence Delirium (PAED) scale every 10 min until PACU discharge.
Procedure: Ophthalmic surgery · Procedure: General anesthesia
Pediatric patients who do not develop emergence delirium in the post-anesthetic care unit (PACU). Emergence delirium will be assessed using the Pediatric Assessment of Emergence Delirium (PAED) scale every 10 min until PACU discharge.
Procedure: Ophthalmic surgery · Procedure: General anesthesia
Ophthalmic surgery will be performed as standard practice of our institution.
General anesthesia will be performed as standard practice of our institution.
The peak PAED score
The peak PAED score is the primary outcome variable for mediation analysis
Time frame: After the completion of surgery, during the PACU stay. PAED score will be measured every 10 minutes during the PACU stay.
