Effect of Different Volumes of Erector Spinae Plane Block on Postoperative Opioid Consumption After Total Abdominal Hysterectomy

Summary

his study aims to investigate the effects of different volumes of ultrasound-guided erector spinae plane block (ESPB) on postoperative pain and opioid consumption in patients undergoing total abdominal hysterectomy. The researchers aim to determine whether varying the volume of local anesthetic in the ESPB can reduce the amount of morphine required by patients and improve pain scores during the first 24 hours after surgery.

Interventions

Type	Name	Description
PROCEDURE	Erector Spinae Plane Block	The ESPB will be performed at the T8-T9 vertebral levels. The T7 vertebra, aligned with the inferior angles of the scapulae, will be identified, and the T8 vertebra will be located one level below via palpation. Patients will be placed in the prone position, and skin preparation will be performed with 10% povidone-iodine. Local anesthesia of the skin and subcutaneous tissue will be provided with 3 ml of 2% lidocaine at the target injection site. Under ultrasound guidance, a sterile-covered linear probe (8 MHz) will be used to visualize the T8 spinous process in the horizontal plane at the midline. The probe will then be rotated to the longitudinal plane, approximately 3 cm lateral to the midline, to visualize the transverse process and the overlying erector spinae muscle. A 22-gauge, 80-mm block needle will be advanced in-plane in a cranio-caudal direction until it contacts the transverse process. After confirming the position between the erector spinae muscle and the transverse proces
