[Peripheral neurologic complications of brachial plexus blocks].
Nerve injury can arise as a complication of peripheral nerve block anesthesia. From the review of the literature remain three factors which alone or in combination, are of special etiologic interest: nerve lesion due to the needle or intraneural injection; toxic effects of the agent injected overall when epinephrine is used; ischemic trauma. The symptoms of such nerve lesions vary from light paresthesia to painful dysesthesia and motor weakness or paralysis. The clinical analysis of these complications does not differ from that in other neurological patients, but must be realized effectively and immediately for avoiding a lawsuit. These postanesthetic neuropathies may benefit from specific treatment or even surgical exploration and external neurolysis. The block should be handled with care: rough paresthesia seeking and intraneural injections should be avoided; short bevel needles and plane solutions should be preferred.
