What is one potential complication of infraclavicular nerve block?

One potential complication of an infraclavicular nerve block is pneumothorax. This complication arises from the anatomical proximity of the brachial plexus to the lung and pleural cavity in the infraclavicular region. During the procedure, especially if the needle is not placed accurately, there is a risk of puncturing the pleura, leading to air entering the pleural space. This can create pressure on the lung, potentially causing it to collapse, which is medically referred to as pneumothorax. Awareness of this risk is crucial for practitioners performing the block to ensure proper technique and minimize complications.
