Nerve Blocks

Nerve Blocks have been previously mentioned in the regional anesthesia section.  They are part of a regional anesthesia technique.  There are many different types of nerve blocks that can be used depending on the circumstances of the surgery.  Today, most of the nerve blocks are given with the use of ultrasound and/or a nerve stimulator which makes them more effective and safer.  They will most likely be given to you before surgery after you have received intravenous sedation.  Below is a list of common blocks according to region and the areas they cover.


Upper Extremities:


Axillary Nerve Block:  Numbs most of the hand and wrist.  Injection is given in the armpit area.
