Brief Summary

The aim of this study was to compare the effectiveness of ultrasound-guided erector spinae plane block and rectus sheet block on postoperative pain in patients undergoing laparoscopic bilateral hernia repair.

Conditions

Erector Spinae Plane Block; Laparoscopic Inguinal Hernia Repair

Keywords

postoperative analgesia; erector spinae plane block; inguinal hernia repair

Outcome Measures

Primary Outcomes (1)

• postoperative pain in patients undergoing laparoscopic bilateral hernia repair

  VAS score

  24 hours after extubation

Secondary Outcomes (1)

• Total Postoperative Opioid Consumption

  immediately after the surgery

Study Arms (3)

ESB (Erector spinae plane block) group

ACTIVE COMPARATOR

The ESP block will be applied under general anesthesia after skin closure lateral decubitus position. The ultrasound probe will be placed in a longitudinal parasagittal orientation approximately 3 cm lateral to the T7 spinous process. Using the inplane technique, a 22-gauge, 80 mm needle will be advanced craniocaudally, and 30 ml of 0.25% bupivacaine will be injected between the erector spinae muscle and the transverse process. ESPB will be performed bilaterally, with 30 ml of local anesthetic administered to the plane of the erector spinae on each side.

Procedure: Erector spinae plane block

RSB (Bilateral rectus sheath block) group

ACTIVE COMPARATOR

Before recovery from anesthesia, an ultrasound-guided rectus sheath block will be performed after the skin incision is closed. the rectus sheath and the posterior aspect of the rectus abdominis muscle an 80 mm, 22-gauge short-tapered needle will be advanced anterolaterally to medially using in-plane placement with real-time assessment, Once the tip is correctly positioned in the intended plane, 20 mL of a local anesthetic, typically bupivacaine at a concentration of 0.25%, will be administered on each side for effective analgesia.

Procedure: Erector spinae plane block

LA infiltration group

ACTIVE COMPARATOR

Patients who will receive local anesthesia only for surgical incisions will be considered the control group. 20 ml of 0.25% bupivacaine will be applied to the surgical incisions, and no plane block will be performed

Procedure: Erector spinae plane block
