Interscalene Brachial Plexus Block

The area is sterilized and draped. A local anesthetic is delivered to the injection site. The brachial plexus nerves are located using ultrasound or electrical nerve stimulation. The area below the shoulder will twitch when the correct nerve is stimulated. Once identified, the injection needle is carefully directed to the brachial plexus. The anesthetic medication is delivered and the needle is removed.
The interscalene brachial plexus block will numb the upper arm and shoulder for several hours to allow surgery or a medical procedure to take place without you feeling any pain. Following your surgery, your arm may be placed in a sling to protect it until your sense of feeling returns. Your doctor will prescribe pain medication for you to use after the block has worn off.
