Cervical plexus block.

Cervical plexus block. Korean J Anesthesiol. 2018 Jul 04;: Authors: Kim JS, Ko JS, Bang S, Kim H, Lee SY Abstract Cervical plexus block (CPB) has been used in various head and neck surgeries to provide adequate anesthesia and/or analgesia. However, it is performed in narrow space of neck area containing many sensitive structures, multiple fascial layers, and complicated nerve innervation. Since intermediate CPB was introduced in addition to superficial and deep CPBs in 2004, there has been some confusion in nomenclature and definition of CPB, particularly the intermediate CPB. Additionally, as the role of ultrasound in the head and neck region has expanded, CPB can be performed more safely and accurately under ultrasound guidance. In this review, authors will describe the methods including ultrasound techniques and clinical applications of conventional deep and superficial CPBs, and discuss the controversial issues of intermediate CPB including nomenclature and associated potential adverse effects that may often be neglected, focusing on the anatomy of the cervical fascial layers and cervical plexus. And finally, authors will attempt to refine the classification of CPB methods based on the target compartments which can be easily identified under ultrasound guidance, with considering the effects of each method of CPB.
