Ultrasound-guided EXORA (external oblique and rectus abdominis plane) block for pain and stress in umbilical hernia repair

The Effect of Ultrasound Guided External Oblique and Rectus Abdominis Plane Block (EXORA) on Neuroendocrine Stress Response in Adults Undergoing Umbilical Hernia Surgery: A Prospective Randomized Controlled Trial

Not applicable Interventional Tanta University · NCT07324863

This trial will test whether adding an ultrasound-guided EXORA block to general anesthesia reduces surgical stress hormones and postoperative pain after elective umbilical hernia repair in adults.

What this trial studies

Adults scheduled for elective umbilical hernia repair under general anesthesia will receive either standard general anesthesia alone or general anesthesia plus an ultrasound-guided external oblique and rectus abdominis plane (EXORA) block. Researchers will measure neuroendocrine stress markers and postoperative analgesia using hormonal assays and pain scoring at defined time points before and after surgery. The EXORA block is a fascial plane technique intended to numb the anterolateral abdominal wall and may complement or fill gaps left by other blocks such as QLB or ESP. Outcomes will include differences in hormonal stress response and measures of postoperative opioid requirement and pain control.

Who should consider this trial

Good fit: Ideal candidates are adults aged 21–65 years with ASA physical status I–II who are scheduled for elective umbilical hernia repair under general anesthesia.

Not a fit: Patients with ASA III–IV, metabolic disorders (like diabetes), those on corticosteroids, with coagulation problems, anatomical abnormalities, complicated/obstructed hernias, or allergy to local anesthetics are excluded and unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, the EXORA block could reduce the hormonal stress response and postoperative pain, potentially lowering opioid needs and improving recovery after umbilical hernia repair.

How similar studies have performed: Other fascial plane blocks (e.g., TAP, QLB, ESP) have demonstrated postoperative analgesic benefit, but the EXORA block is an emerging technique with limited direct outcome data to date.
