Summary

The traditional intra-fascial interscalene brachial plexus block (ISB) is already one of the routine anesthesia methods for pediatric upper limb surgeries in clinical practice. This study aims to clarify the effect of the extra-fascial interscalene brachial plexus block on the diaphragm function of school-age children, as well as its analgesic effect, and to compare it with the traditional intra-fascial ISB. It intends to explore a more effective and safer ISB method for children. With the aim of optimizing techniques and accurately evaluating, to balance the benefits of analgesia and safety, and thereby promoting the development of precise pediatric anesthesia.

Conditions

• Diaphragm Movement

Interventions

Type	Name	Description
PROCEDURE	extra-fascial interscalene brachial plexus block (ISB)	Perform an extra-fascial interscalene brachial plexus block, positioning the needle tip 2-4 mm lateral to the brachial plexus sheath, at a level equidistant between the C5 and C6 roots, measured using the on-screen caliper tool. Inject 0.5 ml/kg of 0.2% ropivacaine for nerve blockade.
PROCEDURE	intra-fascial interscalene brachial plexus block (ISB)	Perform an intra-fascial interscalene brachial plexus block by penetrating the brachial plexus fascia and injecting 0.5 ml/kg of 0.2% ropivacaine.
