Contraindications for interscalene nerve blocks


Side effects/complications of interscalene nerve blocks


Limits of the Method

The application of local anaesthetic into the more cranial area of the plexus will relatively frequently lead to incomplete analgesia of the supply area of the nerves arising from the more caudad region of the plexus (medial cord, ulnar nerve, cutaneous nerve of the arm, medial cutaneous nerve of the forearm). Neither can this be prevented by the administration of high doses of local anaesthetics. Hence, interscalene nerve blocks belong in the realm of shoulder surgery.
