About this trial
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.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Age ≥65 years
Scheduled for elective midline abdominal surgery
ASA physical status I-III
Planned to receive bilateral ultrasound-guided rectus sheath block as part of routine clinical practice
Disqualifiers
Known allergy or hypersensitivity to local anesthetics
Infection or skin lesion at the injection site
Systemic infection or sepsis
Coagulopathy (INR >1.5 or platelet count <100,000/mm³)
Trial population
The study population will consist of geriatric patients (≥65 years) scheduled for elective midline abdominal surgery at S.B.U. Haseki Training and Research Hospital. All participants will receive bilateral ultrasound-guided rectus sheath block as part of routine clinical practice under general anesthesia. Eligible patients who meet the inclusion criteria and provide written informed consent will be prospectively enrolled.

Treatments tested in this trial
Ultrasound-Guided Rectus Sheath Block
Other interventionUltrasound-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.

Postoperative Total Opioid Consumption
Total opioid consumption within the first 24 hours after surgery will be recorded and converted to morphine equivalents (mg). This measure will be used to evaluate the association between ultrasound-derived rectus abdominis muscle parameters and postoperative analgesic requirements.
