After aspirating, 4 mL of anesthetic are injected and innervates the central and proximal part of the palm M assage this bleb of anesthetic medially and laterally of the hand. To block the median nerve, a 27-gauge over the tendon to ensure the nerve is not missed. If the needle is passed under the palmaris longus tendon 3 cm palmaris longus tendon is not present, simply inject proximal to the distal wrist crease. At a depth of about deep to the fascia medial to the fexor carpi radialis 1 cm, 3–5 mL of anesthetic without epinephrine is tendon. If present, the palmaris longus is clearly visible injected slowly, after aspiration to avoid intravascular when the thumb is opposed against the little fnger and injection. On the palmar draw the needle a few millimeters to avoid intraneural surface it supplies sensory innervation to the ulnar one injection. As the needle is withdrawn, inject a further and a half fngers and the hypothenar eminence. To block the posterior tibial nerve, a 25-gauge needle is passed on the medial side of the Achilles tendon at the level of the superior border of the medial malleolus. The needle is advanced until it touches the posterior border of the tibia, then withdrawn 5 mm, and 5 mL of plain lignocaine is injected. The sural nerve runs behind the lateral malleolus to innervate skin over the lateral aspect of the ankle, lateral foot, and a small area on the lateral plantar surface. An injection is made at the level of the superior malleo- lus on the lateral aspect of the Achilles tendon. It innervates the lower part of the ear, behind the saphenous nerve runs with the great saphenous and below the ear, and the angle of the jaw (shaded area). It nerve is blocked by injecting on the fascia of the muscle at its innervates the medial ankle and a small area on the predicted location (dot) medial plantar surface of the foot. To block the nerve, injections are made just medial and lateral to the great about 3 cm from the distal wrist crease and inject saphenous vein anterior to the medial malleolus. If the needle passes into the substance of the tendon, tough resistance will be felt and the needle should be partially withdrawn and redirected. Immediate complications following the injection of It courses alongside the cephalic vein proximal to the local anesthesia include pain, bleeding, hematoma, anatomical snuff box on the radial side of the forearm edema, nerve damage, and adverse drug reactions due and can be felt or rolled on the underlying fascia and to overdosage or allergy .
