Awake Axillary Impella 5.5 Placement - A Feasibility Trial

It is an ultrasound guided brachial plexus nerve block at roots/trunks used to anesthetize the shoulder and upper arm. Goal is to spread local anesthetic around superior and middle trunks of brachial plexus, between the anterior and middle scalene muscles.

PECS II block is comprised of two separate fascial plane blocks to anesthetize anterolateral chest wall using an ultrasound guided injection between the pectoralis major muscle and pectoralis minor muscle at third rib and a second ultrasound guided injection between pectoralis minor and serratus anterior. The goal is a high volume hydro dissection of the two fascial planes to anesthetize anterolateral chest wall and axilla.

This block is a superficial injection to the deep cervical fascia between the investing layer of the deep cervical fascia and the prevertebral fascia in the neck. This block provides anesthesia of the skin of the anterolateral neck and the ante-auricular and retro-auricular areas, as well as the skin overlying and immediately inferior to the clavicle on the chest wall. This is an ultrasound guided injection with the goal of placing the needle tip in the fascial layer underneath the SCM adjacent to the cervical plexus, which is contained within the tissue space between the Cervical fascia and posterior sheath of the SCM.
