LKnative - Thoracic longus nerve block
4 – Scanning technique to block the long thoracic nerve inside the middle scalene muscle
Place the patient supine
Place the high-frequency linear probe in the axial plane and visualize the C5 and C6 spinal nerve roots in the interscalene groove between the anterior and middle scalene muscles. Visualize the long thoracic and dorsal scapular nerves inside the middle scalene muscle posterior to the interscalene groove (see second next page)
Advance the needle with in-plane technique from the posterior end of the probe. Confirm the identity of the long thoracic and dorsal scapular target nerves with electrical nerve stimulation
Inject 5 mL of local anaesthetic until complete perineural spread around the target long thoracic nerve
