Ultrasound-guided TAP block versus single-dose epidural for umbilical hernia pain control

Comparison of the Analgesic Efficacy of Ultrasound-guided Transversus Abdominis Plane Block and Single-dose Epidural Block in Patients Undergoing Umbilical Hernia Surgery.

Observational Sakarya University · NCT07327463

This tests whether an ultrasound-guided transversus abdominis plane (TAP) block or a single-dose epidural better controls postoperative pain in adults having elective umbilical hernia surgery.

What this trial studies

This is an observational comparison of two routinely used analgesic approaches for adults undergoing elective umbilical hernia repair. Patients aged 18–65 with ASA physical status I–II receive either a single-dose epidural or a general anesthetic with a postoperative ultrasound-guided TAP block according to usual clinical practice. Pain intensity will be recorded using the Visual Analog Scale (VAS) at predefined postoperative time points, together with measures of opioid consumption and patient satisfaction. The aim is to determine which approach provides better postoperative pain control and a more favorable side-effect profile in the immediate recovery period.

Who should consider this trial

Good fit: Adults aged 18 to 65 who are scheduled for elective umbilical hernia repair, classified ASA I or II, able to use the VAS, and willing to provide informed consent are the intended participants.

Not a fit: Patients with ASA III or higher, coagulopathy, chronic opioid use or chronic pain syndromes, pregnancy, local infection at the block site, or known allergy to local anesthetics are unlikely to be appropriate or to benefit from the interventions in this comparison.

Why it matters

Potential benefit: If successful, the findings could help clinicians choose the analgesic approach that gives better pain control with fewer opioid-related side effects after umbilical hernia surgery.

How similar studies have performed: Previous randomized and observational reports have shown that TAP blocks can reduce postoperative pain scores and opioid use for abdominal wall surgery, though epidural analgesia remains a strong comparator and results across settings are mixed.
