[Ventricular fibrillation with tolonium chloride: axillary brachial plexus anesthesia led to cessation of circulation].

A 22-year-old patient underwent surgery for a glass wound incision of the hand and anesthesia was carried out using an axillary brachial plexus block with prilocaine. Following surgery the patient developed methemoglobinemia which was treated with tolonium chloride. After administration of the drug the sinus rhythm changed into ventricular fibrillation. The current treatment options of methemoglobinemia will be discussed.
