Ultrasound Guided Erector Spinae Plane Block on Post-operative Pain and Diaphragmatic Dysfunction in Epigastric Hernia

The probe should then slowly be moved laterally until the transverse process is visible. The 100 mm, 25-gauge needle should be inserted using an in-plane approach in the cephalad to caudal direction and advanced under ultrasound guidance towards the transverse process; once the needle tip is below the erector spinae muscle, a small bolus of local anesthetic should be given. The erector spinae muscle should be visualized, separating from the transverse process. After aspiration the local anesthetic (20 ml of 0.25% bupivacaine was injected. Technique was repeated on the other side.

Patients in this group will receive general anesthesia alone.
