About this study

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.

Being tested
extra-fascial interscalene brachial plexus block (ISB), intra-fascial interscalene brachial plexus block (ISB)

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • extra-fascial interscalene brachial plexus block (ISB)Procedure or surgery

    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.

  • intra-fascial interscalene brachial plexus block (ISB)Procedure or surgery

    Perform an intra-fascial interscalene brachial plexus block by penetrating the brachial plexus fascia and injecting 0.5 ml/kg of 0.2% ropivacaine.

Questions about this trial

What is this clinical trial studying?

A study testing extra-fascial interscalene brachial plexus block (ISB) and intra-fascial interscalene brachial plexus block (ISB) in people with Diaphragm Movement, run by Shanghai Jiao Tong University Affiliated Sixth People's Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: enrolling by invitation, as of the sponsor's last update on 3 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To evaluate the rate of diaphragmatic paralysis using ultrasound. (time frame: From enrollment to the end of treatment at 2-3 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Feb 2026.
