A 27-year-old man was bitten by a coral snake in Mexico. Within 24 hours he had ptosis, dysphonia, difficulty chewing, and limb weakness. His symptoms peaked at 72 hours with loss of ambulation. Neurologic examination was consistent with severe myasthenia. Repetitive stimulation of the median nerve showed a postsynaptic defect that was not corrected by edrophonium. He was monitored in an intensive care unit, but received no antivenom globulin or acetylcholinesterase inhibitors. The syndrome abated in 3 weeks.
