New needle technique aims to protect Kids' breathing during arm surgery
NCT ID NCT07382063
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new way to give a nerve block for upper limb surgery in children aged 6-12. The goal is to see if placing the numbing medicine outside the nerve sheath (extra-fascial) reduces the risk of temporary diaphragm paralysis compared to the standard method. Seventy-two children will be enrolled, and doctors will use ultrasound to check diaphragm movement after the block.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Ropivacaine
- What this could lead to
- If successful, this could point toward a safer nerve block technique for children that reduces the risk of diaphragm paralysis.
- What could go wrong
- This is a small, early-stage study with only 72 children, so results may not apply to all patients. The procedure still carries risks like nerve damage or allergic reaction.

Inclusion Criteria: * Age range: School-aged children (6-12 years old). * Type of surgery: Upper limb surgery. * ASA classification: Grades I-II. Exclusion Criteria: * Infection, anatomical deformity, or tumor at the puncture site. * Coagulation disorders (INR \> 1.4, platelet count \< 100 × 10⁹/L). * History of allergy to local anesthetics (ropivacaine). * Severe cardiopulmonary or neurological diseases (e.g., epilepsy, myopathy). * Pre-existing ipsilateral phrenic nerve paralysis or Horner syndrome. * Preoperative long-term use of analgesics (which may affect efficacy assessment). * Parent or child refusal to participate in the study. * Emergency surgery or inability to cooperate with assessments (e.g., severe developmental delay).
