Summary
This study tests whether using a brain monitor (EEG) during laparoscopic surgery helps patients wake up faster, have less pain, and avoid confusion. 136 adults having elective abdominal surgery will be randomly assigned to groups with or without the monitor, in different surgical positions. The goal is to see if this technology improves recovery and comfort after surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Bispectral index monitoring (a device that tracks brain activity during anesthesia)
- What this could lead to
- If it works, this could help doctors adjust anesthesia more precisely, leading to faster recovery and less confusion after surgery.
- What could go wrong
- This is a small, early-stage study that only looks at short-term outcomes. The results may not apply to all surgeries or patients.
