Summary

This study tested two ultrasound-guided nerve blocks to control pain in children aged 7 to 17 after iliac bone graft surgery for jaw repair. Forty children received either a transversus abdominis plane block or a transversalis fascia plane block. The goal was to see which method reduces opioid use and pain scores in the first 24 hours after surgery.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
nerve block procedure
What this could lead to
If one block works better, it could reduce pain and opioid use in children after this type of surgery.
What could go wrong
This is a small, completed trial with only 40 children. Results may not apply to other surgeries or age groups.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Children aged 7 years and older but under 18 undergoing iliac bone grafting for alveoloplasty Exclusion Criteria: * Patients with diseases that affect pain sensitivity differently from the general population (e.g., congenital insensitivity to pain with anhidrosis, complex regional pain syndrome, etc.) * Cases where there is difficulty in expressing pain (due to cognitive or functional deficits, or limited ability to communicate) * Unstable vital signs (heart rate, blood pressure) * Common contraindications for Ropivacaine: 1) Patients with a history of hypersensitivity to this drug or other amide local anesthetics, 2) Patients in a state of major bleeding or shock, 3) Patients with inflammation at or around the site of administration, 4) Patients with sepsis, 5) Intravenous regional anesthesia (Bier block) * History of allergy to opioid medications * Severe renal impairment (Creatinine \>3.0mg/dL) * Severe liver function abnormalities (aspartate transaminase \> 120 unit/L, alanine aminotransferase \> 120 unit/L) * Peripheral nervous system disorders * Other cases deemed unsuitable by the researcher
