Summary

This study will check if measuring belly muscle thickness with ultrasound before surgery can help predict how much opioid pain medicine older patients need after abdominal surgery. Researchers will follow 62 patients aged 65 and older for 24 hours after surgery, recording pain scores and painkiller use. The goal is to find simple ways to personalize pain management for each patient.
