Superficial and deep cervical plexus block for carotid artery surgery: A prospective study of 1000 blocks

Abstract

We conclude that superficial and deep cervical plexus block has a high success rate, low complication rate, and high patient acceptance rate. Caution should, however, be exercised to ensure a low intravascular injection rate which is of most concern with this technique, because blood was aspirated in 30% of patients during performance of the block.
