ESP vs. EXORA Blocks for Analgesia in Laparoscopic Cholecystectomy

NCT06900413 · Status: NOT_YET_RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 56

No results posted yet for this study

Summary

Patients undergoing laparoscopic cholecystectomy may experience moderate to severe postoperative pain. Effective postoperative analgesia enhances patient comfort and accelerates recovery. This study aims to compare the effects of Erector Spinae Plane (ESP) and External Oblique and Rectus Abdominis Plane (EXORA) blocks on postoperative pain management and analgesic consumption.

The study is designed as a prospective, randomized, double-blind trial. Patients will be randomly assigned to groups, and both practitioners and evaluators will be blinded to group assignments. Our hypothesis is that the EXORA block will provide superior analgesia and require less analgesic consumption compared to the ESP block. The results will be assessed in terms of postoperative pain management, patient comfort, and additional analgesic requirements.

Conditions

  • Erector Spinae Plane Block
  • Laparoscopic Cholecystectomy
  • Plane Block

Interventions

PROCEDURE

Group ESP

Experienced anesthesiologists with at least five years of expertise in regional anesthesia will perform the blocks under ultrasound guidance. A 4.0-12.0 MHz linear ultrasound probe (Affiniti 50; Philips) will be used. The ESP block will be applied at the T8 level on the right side, using an in-plane approach, while the patient is in a sitting position. The probe will be placed 2-3 cm lateral to the vertebra in a sagittal position to visualize the erector spinae muscle and transverse processes. A 22G, 100 mm block needle (Stimuplex® Ultra, Braun, Germany) will be advanced in a craniocaudal direction. The correct needle position will be confirmed by injecting 0.5-1 mL of isotonic NaCl and observing the spread via hydrodissection. Finally, 0.3 mL/kg of 0.25% bupivacaine will be administered, ensuring cranial and caudal spread of the local anesthetic.

PROCEDURE

Group EXORA

Experienced anesthesiologists with at least five years of expertise in regional anesthesia will administer the blocks under ultrasound guidance. A 4.0-12.0 MHz linear ultrasound probe will be placed laterally to the xiphoid process on the parasternal line in a sagittal position. The probe will be moved craniocaudally to identify the 6th rib and further advanced caudally to locate the 8th rib. Once the rectus abdominis muscle and 8th costal cartilage are identified, a 22G, 100 mm block needle will be used to administer 0.3 mL/kg of 0.25% bupivacaine. The correct spread of the local anesthetic will be confirmed via ultrasound.
