An interscalene block was attempted in the preoperative area and combined with general anesthesia for surgery. Interscalene brachial plexus blocks (ISB) only using nerve stimulation or eliciting paresthesias are associated with a high rate (up to 100 %) of phrenic nerve blocks. The supraclavicular branches of the cervical plexus, supplying the skin over the acromion and clavicle, are also blocked due to the proximal and superficial spread of local anesthetic. It is a great block for distal clavicle, shoulder, and proximal humerus procedures. The interscalene block is included in the category of regional anesthesia and is one of the most commonly used types of peripheral nerve blocks.

Horner syndrome; Miller's Anesthesia, 7th edition, Churchill Livingstone: p 409, 1640-3. The needle should not be placed deeper than 2-3 cm in most patients. In the emergency department, ultrasound-guided brachial plexus block can provide rapid and definitive pain relief from traumatic injuries to the upper extremity. The interscalene block is particularly well suited for ultrasound guidance due to the presence of good ultrasound landmarks and the superficial location of the brachial plexus at this level. These anterior rami pass through their respective intervetebral foramina and converge laterally and caudally to form the trunks of the brachial plexus. An interscalene brachial plexus block uses injected medication to numb the shoulder and upper arm prior to surgical procedures or repositioning (reduction) of a dislocated shoulder. One advantage of the interscalene block over the supraclavicular is that it blocks part of the cervical plexus. The stellate ganglion, phrenic, and recurrent laryngeal nerve are near the brachial plexus. Interscalene Brachial Plexus Block listed as IBPB.
