Rectus Abdominis Muscle Parameters and Postoperative Opioid Consumption in Geriatric Patients
ClinicalTrials.gov Studies
Summary
This prospective observational study (NCT07545824) registered April 22, 2026 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.

What changed
This document registers a new prospective observational clinical study on ClinicalTrials.gov. The study evaluates whether preoperative ultrasound measurements of the rectus abdominis muscle (thickness and thickening fraction) can predict postoperative opioid consumption in geriatric patients undergoing abdominal surgery. Pain scores and analgesic requirements will be recorded within the first 24 hours post-surgery. An ultrasound-guided rectus sheath block is listed as the study intervention.
For healthcare providers and clinical investigators involved in geriatric surgical care, this study may inform future personalised analgesic protocols. Institutions conducting abdominal surgery on older adults should monitor emerging findings, as ultrasound-derived muscle parameters could eventually serve as preoperative risk-stratification tools for opioid requirements.

Rectus Abdominis Muscle Parameters and Postoperative Opioid Consumption in Geriatric Patients
Observational NCT07545824 Kind: OBSERVATIONAL Apr 22, 2026
Abstract
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.
