Monitoring anesthesia depth using EEG to improve recovery and cognition

EEG-based Depth of Anesthesia-monitoring During General Anesthesia - Effects on Time to Wake-up and Post-operative Cognition

Not applicable Interventional Oslo University Hospital · NCT04529304

This study tests if using brain wave monitoring during surgery can help doctors give the right amount of anesthesia to improve recovery and thinking skills afterward.

What this trial studies

This study investigates the use of EEG-based monitoring to assess the depth of anesthesia during surgery. By analyzing raw EEG waveforms alongside established indexes, the researchers aim to tailor anesthetic dosages more effectively, potentially reducing the total amount of anesthetic used. The study also evaluates the impact of this individualized approach on postoperative cognitive function using standardized cognitive assessments. The goal is to minimize complications related to anesthesia, such as delayed recovery and cognitive dysfunction.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over the age of 18 who are undergoing surgical procedures requiring anesthesia.

Not a fit: Patients with psychiatric disorders, pregnancy, breastfeeding, or those on antiepileptic drugs may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to faster recovery times and improved cognitive outcomes for patients after surgery.

How similar studies have performed: Previous studies have shown promising results in using EEG for anesthesia monitoring, but this specific approach is relatively novel.
