Using an AI system to manage fluid therapy after high-risk abdominal surgery

"Personalized Fluid Administration Using an AFM System for Goal Directed Fluid Therapy on Postoperative Outcome in High-risk Patients Undergoing High-risk Abdominal Surgery: A Multicenter Stepped-wedge, Cluster-randomized Clinical Trial

Not applicable Interventional Assistance Publique - Hôpitaux de Paris · NCT06011187

This study is testing whether an AI system can help doctors give the right amount of fluids to patients after high-risk abdominal surgery to see if it improves recovery.

What this trial studies

This clinical trial evaluates the effectiveness of an Assisted Fluid Management (AFM) system designed to enhance goal-directed fluid therapy (GDFT) in high-risk surgical patients. The AFM system utilizes artificial intelligence to suggest fluid bolus administration, analyze hemodynamic responses, and continuously reassess patient needs, aiming to improve adherence to fluid management protocols. By addressing the variability in fluid resuscitation practices, the study seeks to determine if the AFM system can lead to better postoperative outcomes compared to routine care.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older undergoing elective high-risk abdominal surgery with specific medical conditions that increase surgical risk.

Not a fit: Patients who are not undergoing high-risk abdominal surgery or do not meet the specified high-risk criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce postoperative complications in high-risk surgical patients.

How similar studies have performed: While there have been studies on goal-directed fluid therapy, the use of the AFM system in a large outcome study is novel and has not been extensively tested.
