Overview
This study aims to evaluate the efficacy of ultrasound-guided external oblique and rectus abdominis plane block on the neuroendocrine stress response and postoperative analgesia in adults undergoing umbilical hernia repair.
Description
Umbilical hernias of the abdomen are defined as a non-inguinal, non-hiatal defect in the fascia of the abdominal wall. Surgical stress response refers to the physiologic response to surgery and the hormonal and metabolic changes that follow it.
Fascial plane blocks are gaining attention for perioperative analgesia due to their efficacy and safety profiles. The external oblique and rectus abdominis plane (EXORA) block is an emerging technique that provides a sensory block to the anterolateral abdominal wall, potentially filling gaps left by other commonly used blocks, such as the quadratus lumborum (QLB) or erector spinae plane (ESP) blocks.
