Transversalis fascia plane versus transversus abdominis plane block for children's pain after laparoscopic abdominal surgery

Comparison of the Analgesic Effects of Ultrasound-Guided Transversalis Fascia Plane Block and Transversus Abdominis Plane Block in Pediatric Laparoscopic Surgery

Observational Sakarya University · NCT07242196

This study will test whether the transversalis fascia plane block or the transversus abdominis plane block provides better pain relief for children aged 6 months to 16 years undergoing laparoscopic abdominal surgery.

What this trial studies

This prospective observational study compares two ultrasound-guided regional anesthesia techniques—transversalis fascia plane (TFP) block and transversus abdominis plane (TAP) block—in pediatric patients having laparoscopic abdominal procedures. Eligible patients are aged 6 months to 16 years with ASA physical status I–II and will receive one of the blocks under ultrasound guidance as part of perioperative care. Primary outcomes include postoperative analgesic efficacy and duration, with secondary measures such as opioid requirement, dermatomal coverage, parental satisfaction, and adverse events tracked postoperatively. The single-center study is conducted at Sakarya University’s Anesthesiology and Reanimation Department.

Who should consider this trial

Good fit: Children aged 6 months to 16 years with ASA physical status I or II who are scheduled for elective laparoscopic abdominal surgery and have no contraindications to regional anesthesia are ideal candidates.

Not a fit: Patients with ASA III–IV status, bleeding disorders, infection at the injection site, known allergy to local anesthetics, or those undergoing procedures outside the blocks' expected dermatomal coverage are unlikely to benefit from participation.

Why it matters

Potential benefit: If one block provides demonstrably better and longer pain relief, children may experience less pain, reduced opioid needs, and faster, more comfortable recovery after laparoscopic surgery.

How similar studies have performed: TAP blocks are well-established with multiple studies showing benefit in adults and children, while the transversalis fascia plane block is a newer modification with limited pediatric data.
