Can your brain waves predict your pain after surgery?

This study aims to understand if specific brain wave patterns measured during surgery are linked to how much pain a patient feels after waking up. Researchers will record brain activity from 80 adults having planned abdominal surgery while they receive small, calibrated electrical skin tests under anesthesia. The goal is to see if these brain signals can help predict who might experience more severe pain after their operation, which could lead to better pain management in the future.
