STIL block versus RIB with sub-serratus plane block for pain relief after pediatric chest surgery

Official title: Ultrasound- Guided Subtransverse Process Interligamentary Plane Block Versus Rhomboid Intercostal Block Combined With Sub-Serratus Plane Block for Analgesia in Pediatric Thoracotomy: A Randomized Controlled Study

Run by Tanta University · NCT07666334 · Data updated 2026-11-12

This study tests whether the STIL plane block provides comparable or better pain relief than the combination of RIB and sub-serratus plane block in children after thoracotomy.

Is this trial a fit for you?

Likely a good fit

Children aged 6 to 12 years scheduled for thoracic surgery with thoracotomy incision under general anesthesia, ASA I–II.

Probably not a fit

Patients lacking adequate analgesia response to regional block or who have contraindications to regional anesthesia may not experience benefit.

What this trial studies

This interventional study compares two ultrasound-guided regional anesthesia techniques for postoperative analgesia in pediatric thoracotomy patients. Eligible children aged 6 to 12 years, ASA I–II, will be randomized to receive either a subtransverse process interligamentary (STIL) plane block or a rhomboid intercostal block (RIB) with a sub-serratus plane block, in addition to standard IV analgesia. The primary aim is to determine the effectiveness of pain control in the immediate postoperative period, with safety monitoring given the thoracic approach. STIL targets thoracic nerves without entering the paravertebral space, potentially reducing complications. Prior evidence suggests RIB and RISS can provide good analgesia; this trial evaluates whether STIL offers similar or superior relief in a pediatric surgical population.

Why it matters

Potential benefit: If successful, STIL block could provide effective postoperative pain control with a favorable safety profile in children undergoing thoracotomy.

How similar studies have gone: Previous reports show good analgesia with RIB and sub-serratus plane blocks; STIL is a newer approach under evaluation for efficacy and safety.
