Rectus Abdominis Muscle Parameters and Postoperative Opioid Consumption in Geriatric Patients
Sponsor: Istinye University
Summary
This prospective observational study aims to evaluate the relationship between ultrasound-derived rectus abdominis muscle thickness and thickening fraction and postoperative opioid consumption in geriatric patients undergoing abdominal surgery. Preoperative ultrasonographic measurements will be performed during routine clinical care, and postoperative pain scores and analgesic requirements will be recorded within the first 24 hours. The findings may help improve individualized analgesic strategies by identifying patient-specific predictors of postoperative opioid needs.

Interventions
Ultrasound-Guided Rectus Sheath Block
Ultrasound-guided rectus sheath block will be performed as part of routine clinical practice in geriatric patients undergoing abdominal surgery. No additional intervention will be introduced for study purposes. Ultrasound-derived rectus abdominis muscle thickness and thickening fraction will be measured preoperatively, and postoperative opioid consumption and pain scores will be recorded within the first 24 hours.
