TAP block vs. epidural: which eases hernia surgery pain better?
NCT ID NCT07327463
First seen Jun 27, 2026 · Last updated Jul 08, 2026 · Updated 2 times
Summary
This study looks at two common ways to manage pain after umbilical hernia surgery: an ultrasound-guided TAP block and a single-dose epidural. Researchers will measure pain levels in 30 adults at different times after surgery using a simple 0-10 pain scale. The goal is to see which method offers better pain control and patient satisfaction.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ultrasound-guided transversus abdominis plane (TAP) block and single-dose epidural anesthesia
- What this could lead to
- If this study shows one method is clearly better, it could help doctors choose the most effective pain relief for patients after umbilical hernia surgery.
- What could go wrong
- This is a small, observational study with only 30 participants, so results may not apply to everyone. It compares routine care, not a new treatment, so no major breakthrough is expected.

Who is studied
The study population consists of adult patients aged 18 to 65 years with American Society of Anesthesiologists (ASA) physical status I or II who are scheduled to undergo elective umbilical hernia surgery. Patients included in the study receive anesthesia and postoperative analgesia as part of routine clinical practice, either with single-dose epidural anesthesia or with general anesthesia followed by ultrasound-guided transversus abdominis plane (TAP) block. All patients are managed according to standard institutional surgical and anesthetic protocols. No additional interventions, medications, or procedures are performed for research purposes. Postoperative pain assessment is conducted using the Visual Analog Scale (VAS) during the postoperative period. The study population reflects real-world clinical practice in umbilical hernia surgery.
