Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients aged 18-70 scheduled for major abdominal surgery lasting more than 2 hours with an ASA score of I-III.

Probably not a fit

Patients with uncontrolled hypertension, chronic kidney disease, or those undergoing emergency surgeries may not benefit from this study.

What this trial studies

This study evaluates the impact of processed electroencephalography (pEEG)-guided general anesthesia on reducing the need for norepinephrine during major abdominal surgeries. By minimizing intraoperative hypotension (IOH) through tailored anesthesia, the study aims to decrease postoperative complications, particularly acute kidney injury (AKI). Participants will be randomly assigned to receive either pEEG-guided or non-pEEG-guided anesthesia, with outcomes assessed post-surgery. The research addresses a critical gap in managing IOH and its associated risks in surgical patients.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of postoperative acute kidney injury in patients undergoing major abdominal surgery.

How similar studies have gone: While the use of pEEG in anesthesia is gaining interest, this specific approach to managing IOH in major abdominal surgery is relatively novel and has not been extensively tested in prior studies.
