Effects of Extra-fascial Interscalene Brachial Plexus Block on Diaphragmatic Function in School-Aged Children
Enrolling by invitation · Not applicable
Conditions studied: Diaphragm Movement
In brief
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.
