Perfusion Index to Measure Postoperative Pain in Kids After Adenotonsillectomy

Official title: Evaluation of Postoperative Pain With Perfusion Index Measurement in Pediatric Adenotonsillectomy: A Randomized Controlled Trial

Run by Istanbul University · NCT07915804 · Data updated 2026-11-12

This study tests whether the perfusion index can reliably reflect pain levels in children aged 1–12 after adenotonsillectomy, comparing standard care with an added glossopharyngeal nerve block.

Is this trial a fit for you?

Likely a good fit

Pediatric patients aged 1–12 years scheduled for elective adenotonsillectomy, ASA I–II, with parental/guardian consent.

Probably not a fit

Patients with ASA III–IV, perioperative instability, known local anesthetic allergy, chronic pain or neurological disease, or other conditions affecting peripheral perfusion may not benefit from this approach.

What this trial studies

This single-center randomized trial will enroll 50 pediatric patients aged 1–12 undergoing elective adenotonsillectomy. Participants will be randomized to receive either standard general anesthesia with multimodal analgesia or the same regimen plus a bilateral glossopharyngeal nerve block with 0.25% bupivacaine. Postoperative perfusion index measurements will be compared to established pain scales (FLACC and Wong-Baker) to determine if PI aligns with patient-reported pain indicators. A standardized perioperative protocol will be used for all participants, including antibiotic prophylaxis, steroids, acetaminophen, and temperature management. The study aims to determine if PI can serve as an objective pain measurement tool in this pediatric surgical population.

Why it matters

Potential benefit: If successful, PI could provide an objective, real-time measure of postoperative pain in children, potentially improving pain management.

How similar studies have gone: Previous work has explored perfusion-based measures and nerve blocks for pain, but using perfusion index as a primary objective pain metric in this setting is novel and not yet established.
