Summary

This trial tests whether a device that tracks heart rate patterns can help doctors give just the right amount of anesthesia during gallbladder removal surgery. The goal is to use less anesthetic and pain medicine, helping patients wake up faster and leave the recovery room sooner. The study includes 125 adults aged 19 to 65 who are scheduled for this surgery.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Analgesia/Nociception Index (ANI) monitor
What this could lead to
If successful, this approach could make anesthesia safer and more personalized, reducing side effects and speeding recovery after surgery.
What could go wrong
This is a small, early-stage trial focused on a specific surgery. The monitor may not improve outcomes for all patients or procedures.
