Analyzing EEG Changes During Surgery to Measure Pain Response
Quantitative Analysis of EEG Changes in Response to Nociception
This study is trying to see how brain activity changes during and after laparoscopic surgery to better understand pain responses in patients under general anesthesia.

What this trial studies
This observational study aims to quantify nociception in patients undergoing laparoscopic surgery by using the Analgesia Nociception Index (ANI) during general anesthesia. It will analyze the differences in electroencephalogram (EEG) readings based on the level of nociception experienced by patients. Additionally, the study will continue to assess nociception during the recovery phase and correlate EEG changes with nociception levels. The goal is to enhance understanding of pain responses in surgical settings.
Who should consider this trial
Good fit: Ideal candidates for this study are adults aged 19 and older who are scheduled for laparoscopic surgery.
Not a fit: Patients with certain heart conditions, central nervous system diseases, or those on specific medications may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved pain management strategies during and after laparoscopic surgeries.
How similar studies have performed: While the approach of using EEG to measure nociception is not widely established, similar studies have shown promising results in understanding pain responses.
