Robot vs. doctor: can a machine outperform anesthesiologists in fluid management?
NCT ID NCT01950845
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether an automated closed-loop system could better manage fluid levels during major abdominal surgery compared to standard care by an anesthesiologist. Forty-six high-risk patients were randomly assigned to receive fluids via the automated system or manual control. The main goal was to see if the automated system improved cardiac output during surgery.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Closed-loop automated fluid administration system (LIR®)
What this could lead to
If successful, this system could help doctors give fluids more precisely during surgery, potentially improving recovery and reducing complications.
What could go wrong
This is a small, early-stage study with only 46 patients, so results may not apply to everyone. The system may not work better than standard care and could have technical issues.
