EEG versus BIS monitoring to reduce emergence delirium in young children under general anaesthesia

Comparison of the Effect of EEG and BIS-guided Anaesthesia on the Incidence of Emergent Delirium in Children: a Prospective Monocentric Study

Not applicable Interventional University Hospital Ostrava · NCT07534215

This study will test whether using EEG or BIS monitoring during general anaesthesia helps reduce emergence delirium in children aged 1–6 having surgery.

What this trial studies

Children aged 1–6 undergoing elective procedures receive a standardized anaesthesia protocol including oral midazolam premedication and measures of preoperative anxiety (PSAS and m‑YPAS). During anaesthesia they are managed either with EEG-guided titration of sevoflurane interpreted by an EEG specialist or with BIS monitoring targeting BIS values of 40–60. Airway management (laryngeal mask or intubation) and intraoperative analgesia are provided per protocol, and the time to initiation of depth monitoring is recorded. The primary outcome is the incidence of emergence delirium in the immediate postoperative period.

Who should consider this trial

Good fit: Ideal candidates are children aged 1–6 years scheduled for elective procedures such as hernioplasty or orchidopexy with ASA physical status I–II and parental or guardian consent.

Not a fit: Children older than 6, those with ASA III or higher, neurological disease, severe hearing or vision impairment, or whose parents do not consent are not eligible and would not benefit from this protocol.

Why it matters

Potential benefit: If successful, the monitoring approach could reduce how often and how severely children experience emergence delirium, making recovery smoother and less distressing for patients and families.

How similar studies have performed: BIS- and EEG-guided anaesthesia have shown reductions in delirium or excessive anaesthetic depth in adult studies, but pediatric evidence—especially in very young children—is limited and mixed.
