[Transient total motor aphasia. A complication of an axillary brachial plexus block].
Hypo- and hypertension, arrhythmias, bradycardia extending to cardiac arrest with circulatory failure, pneumothorax, allergic reactions with or without anaphylactic shock, production of methaemoglobin, vomiting, vertigo, disorientation, acoustic and visual disorders, tinnitus, slurred speech, muscle contractions, unconsciousness, and epileptic seizures are well-known complications associated with local anaesthetics. We have observed an additional central nervous system complication: a case of transient, total motor aphasia (Broca aphasia) in a 50-year-old patient after axillary blockade of the brachial plexus. Possible causes such as type and dosage of local anaesthetic or a transient ischaemic attack in the area of the prerolandic artery are discussed and related to the literature. Ultimately, however, it is still not apparent why this complication could appear although there was no overdosage intravascular injection, or abnormality of the pulse or blood pressure, and why its manifestation was limited to a motor aphasia.
