Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
ESPB Group
Erector spinae plane block will be applied to the patients in this group.
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.
EOIPB Group
External Oblique - Intercostal Plane block will be applied to the patients in this group.
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.
