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

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

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.
