5 – Scanning technique of the median nerve at the elbow

Place the patient supine

Place the high-frequency linear probe in the axial plane in the elbow crease

Visualize the pulsatile brachial artery

Locate the hyperechoic cross-sectional view of the median nerve just medial to the brachial artery (see sonoanatomy page)

Insert the needle with in-plane approach from the medial end of the probe

Inject 3-5 mL of local anaesthetic perineurally
