What this trial studies

This study investigates the use of a hypotension prediction index (HPI) to guide management during major upper gastrointestinal surgeries, aiming to reduce the incidence of intraoperative hypotension (IOH). By monitoring patients' blood pressure and utilizing an algorithm to predict impending hypotension, the study seeks to minimize the duration and severity of IOH and its associated postoperative complications. Additionally, it explores the relationship between metabolomic changes and the occurrence of postoperative ileus in patients undergoing these surgical procedures. The outcomes will be assessed both in the short term, within 30 days post-surgery, and long term, within one year.

Who should consider this trial

Good fit: Ideal candidates are patients scheduled for elective major upper gastrointestinal surgery who are not undergoing laparoscopic procedures.

Not a fit: Patients undergoing laparoscopic surgery will not benefit from this study as they are excluded from participation.

Why it matters

Potential benefit: If successful, this approach could significantly reduce postoperative complications and improve recovery times for patients undergoing major upper gastrointestinal surgery.

How similar studies have performed: While the application of HPI in this context is relatively novel, previous studies have shown promise in using predictive algorithms to manage intraoperative hypotension.
