PECS II block

/

The pecs II block is based on the concept that the intercostal nerves can be blocked as they travel through the intra-muscular planes of the upper thorax.  This let's you avoid intercostal or paravertebral blocks.  It is very similar to the TAP block concept.  

Developed by breast surgeons, it works for the upper chest and axilla, importantly it gets the intercostobrachial nerve.
