Infraclavicular brachial plexus block effects on respiratory function and extent of the block.
Axillary block is devoid of severe respiratory complications. However, incomplete anesthesia of the upper limb is the main disadvantage of the technique. Theoretically, the more proximal infraclavicular approach would produce a more extensive block without the risk of pneumothorax. However, neither its effects on respiratory function nor a detailed characterization of the extent of neural block has been assessed. The goal of this study was to evaluate the possible changes in respiratory function and also the extent of the block after infraclavicular block. ⋯ Infraclavicular block does not produce a reduction in respiratory function.

Injection of the piriformis muscle by fluoroscopic and electromyographic guidance.
There is not a universally accepted single technique for injection of the piriformis muscle that has validated exact placement of the needle tip within the piriformis muscle. ⋯ Using this methodology, injections on 17 occasions in 11 patients resulted in needle placement within the piriformis muscle.
