Summary

The aim of this study is to compare the postoperative analgesic efficacy of bilateral erector spinae plane block and bilateral external oblique-intercostal plane block in patients undergoing open ventral hernia repair.

Detailed description

The effectiveness of trunk blocks applied at equivalent doses will be evaluated in order to most effectively treat postoperative pain, minimize nausea and vomiting, and optimize the comfort of patients during the postoperative period after open ventral hernia repair operations. The methods used in this study are proven safe in ventral hernia repair surgery and other abdominal surgeries, and are routinely performed in our clinic. The procedures performed pose no additional risks to patients compared to routine procedures.

Conditions

• Ventral Hernia
• Postoperative Pain
• Postoperative Nausea
• Postoperative Vomiting

Interventions

Type	Name	Description
PROCEDURE	Erector Spine Plane Block	Bilateral erector spinae plane block was performed under aseptic conditions at the T7 vertebral level using ultrasound guidance with a convex probe. An 80-mm peripheral nerve block needle was inserted 3-4 cm lateral to the midline with an in-plane approach to the fascial plane deep to the erector spinae muscle. After negative aspiration and hydrodissection with 1-3 ml of saline, 30 ml of 0.25% bupivacaine was injected on each side, with craniocaudal spread confirmed by ultrasound. Patients were then positioned for surgery.
PROCEDURE	External Oblique - Intercostal Plane Block	Bilateral external oblique-intercostal plane block was performed under aseptic conditions by identifying the 6th and 7th ribs along the midclavicular line. Using ultrasound guidance with the probe placed parallel to the midclavicular line, the ribs, intercostal muscles, external oblique muscle, and pleura were visualized. A 50-mm block needle was advanced craniocaudally into the plane between the external oblique and intercostal muscles. After negative aspiration and hydrodissection with 1-3 ml saline, 30 ml of 0.25% bupivacaine was injected on each side, with craniocaudal spread confirmed by ultrasound. Patients were then positioned for surgery.
