This study identifies consistent anatomical landmarks for safe infraclavicular brachial plexus blocks. Precise measurements ensure accurate needle placement, minimizing risks like pneumothorax and vascular injury for anesthesiologists.
Area of Science:
- Anatomy
- Regional Anesthesia
Context:
- The infraclavicular fossa is a consistent anatomical space.
- Brachial plexus blocks are essential regional anesthesia techniques.
Purpose:
- To determine precise anatomical landmarks within the infraclavicular fossa for brachial plexus block.
- To propose a safe and effective technique for infraclavicular brachial plexus block.
Summary:
- Anatomical measurements were taken in 100 cadavers to locate brachial plexus fascicles within the infraclavicular fossa.
- The average distance from the clavicle's anterior surface to the brachial plexus was 2.49 cm, and from the deltoid-clavicular angle to fascicle projection was 2.21 cm.
- The infraclavicular fossa was present in 96% of cases, with brachial plexus fascicles located in 97.9% of these.
Impact:
- Provides anesthesiologists with precise landmarks for safe infraclavicular brachial plexus blocks.
- Reduces the risk of pneumothorax and vascular injury during the procedure.
- Facilitates the return to practicing brachial plexus blocks in the infraclavicular space.
