Erector Spinae Plane Block versus Transversus Abdominis Plane Block for Robotic Inguinal Hernia Repair: A Blinded, Active-Controlled, Randomized Trial.

Background: Regional anesthetic nerve blocks are widely used in the treatment of pain after outpatient surgery to reduce opioid consumption. Erector spinae plane (ESP) block is a recently described technique with promising results in different scenarios.

Objectives: To compare ESP block efficacy with the commonly used transversus abdominis plane (TAP) block in patients undergoing robot-assisted inguinal hernia repair.
