Procainamide-induced myasthenic crisis.
We describe a case of procainamide-induced respiratory failure in a myasthenic patient with no prior history of respiratory weakness. Respiratory failure was induced secondary to procainamide alone since no N-acetyl-procainamide level was detectable. The patient's strength rapidly improved and he was successfully extubated 12 h after the offending dose.
