Infrared thermography to predict erector spinae plane block success in children having unilateral inguinal hernia repair

Official title: Infrared Thermography for Prediction of Successful Erector Spinae Plane Block in Unilateral Inguinal Hernia Surgery in Paediatric Patients: A Prospective Observational Study

Run by Cairo University · NCT07161375 · Data updated 2026-11-12

This project will test whether temperature changes seen on a thermal camera can tell if an erector spinae plane block worked in children aged 3 months to 6 years having unilateral inguinal hernia repair under general anesthesia.

Is this trial a fit for you?

Likely a good fit

Children aged 3 months to 6 years, ASA physical status I–II, scheduled for elective unilateral open inguinal hernia repair whose parents or guardians consent and who have no contraindications to regional anesthesia are ideal candidates.

Probably not a fit

Children with skin conditions that interfere with thermal imaging, baseline fever above 37.5 °C, coagulopathy, infection at the injection site, known allergy to local anesthetics, preexisting neuropathy, or those in emergency or re-do cases are unlikely to benefit from this approach.

What this trial studies

This observational study will enroll children aged 3 months to 6 years (ASA I–II) undergoing elective unilateral open inguinal hernia repair at Cairo University. Participants will receive ultrasound-guided erector spinae plane blocks under general anesthesia while infrared thermography records temperature changes (ΔT) at predefined time points. The recorded ΔT values will be compared with clinical indicators of block success and any need for rescue analgesia to determine predictive accuracy. The aim is to determine whether early thermal changes reliably indicate a successful block so clinicians can apply rescue techniques or proceed confidently.

Why it matters

Potential benefit: If successful, this method could provide a quick, noninvasive way to confirm block success early, improving pain control and operating room efficiency.

How similar studies have gone: Similar uses of infrared thermography to predict peripheral or regional nerve-block success have shown promising results in adults, though pediatric-specific data remain limited.
