– Place the patient supine with the arm abducted and elbow bend 90 degrees
– Place a high-frequency linear probe axially in the axillary crease to obtain a cross-sectional view of the axillary artery
– Optimize depth, gain and focus
– Insert the needle with in-plane technique from the cranial end of the probe
– Block the nerves individually with 3-5 mL of local anaesthetic per nerve or deposit local anaesthetic periarterially; always block the musculocutaneous nerve separately
Place the patient supine with abducted arm and bend elbow and insert the needle with in-plane approach
