Predicting how Propofol affects anesthesia depth using EEG data

Prediction of Propofol Effect Compartment Concentrations

Karl Landsteiner University of Health Sciences · NCT05940142

This study is testing if new ways of analyzing brain activity can better predict how deep anesthesia goes when using Propofol during surgery.

What this trial studies

This observational study aims to develop and validate models that can accurately predict the effects of Propofol on anesthesia depth by analyzing EEG data collected during surgical procedures. Participants will undergo planned Total Intravenous Anesthesia (TIVA) with Propofol, and their EEG readings will be recorded to compare the effectiveness of new predictive models against existing ones, such as the Schnider model. The study seeks to enhance clinical practices in anesthesia management by identifying the most reliable prediction model.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 or older who are scheduled for surgeries requiring TIVA with Propofol.

Not a fit: Patients with contraindications to Propofol, those undergoing neurosurgical operations, or those requiring intensive care before or after surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more precise dosing of Propofol, improving patient safety and outcomes during anesthesia.

How similar studies have performed: While there have been studies on anesthesia depth prediction, this specific approach using EEG data for Propofol is relatively novel.

Eligibility criteria
