Sean Malin, MD, Acute Pain FellowKyle Marshall, MDUniversity of Colorado HospitalCRASH 2016

Why is this “advanced???”

Steep needle approach Holds a catheter well Most are not comfortable with this block, compared to ISB, SCV, Ax

Brachial plexus block at level of the Cords

Three cords:

Medial: Musculocutaneous, ½ of Median

Lateral: ½ of Median, Ulnar

Posterior: Radial, Axillary

Great block for any surgery distal to shoulder

Low incidence of phrenic block ISB: 100%, SCV 50%, ICV 0%  Great for OSA, O2 dependents, Severe COPD

Low incidence of pneumothorax

Best location for placement of catheters Anchored in Pec major and minor Little movement compared to supraclavicular Cleaner than axillary

One injection point Don’t have to chase Musculocutaneous

Positioning Patient Supine

Arm abducted (may keep elbow ext or flex)

Probe placement Parellel to spine, below Coracoid process

Axillary artery in center of screen, usually 3‐4cm deep

Landmarks Axillary Artery – Cords surround

Goal needle placement: Cephalad to Caudad, below Coracoid process Steep approach, may not see needle well Tip behind Axillary artery at “6 o’clock”

Injection: Should see artery “lifted” by local Classic U‐shape infiltration will cover all cords

Catheter:  leave catheter posterior to artery, so that Medial cord is not 

spared. Do not just blindly feed catheter; no sheath to keep local in

Technically difficult compared to ISB, SCV Steep angle = poor needle visualization Ulnar can be spared with poor needle placement

Difficult vascular compression Relative contraindication for coagulopathy, blood thinners, antiplatelet meds

Misses the suprascapular nerve This block not sufficient for shoulder surgery▪ Good for post‐op analgesia in severe pulmonary disease

Vascular puncture 5.5% Transient neurological deficit 2.6% Horner’s Syndrome 2.2% LAST 0.2% Phrenic Nerve Blockade 0‐3% Pneumothorax 0.2‐0.7%

Holds catheter very well.
