Medically Challenging Cases
•Brachial plexus blocks for shoulder surgery are commonly performed, notably the interscalene block (ISB).
•An ISB causes phrenic nerve paralysis >70% of the time, making it an unsuitable block for patients with compromised pulmonary function.
The superior trunk of the brachial plexus can be blocked selectively and also targets the C5 and C6 nerve roots but only affects the phrenic nerve in around 5% of cases when using 15cc volume.

There is a scarcity of case reports on the effective use of a low volume superior trunk block (STB) as a primary anesthetic for shoulder surgery in high-risk patients.
