N 6

A technician of the chemical laboratory was not careful working with a toxic volatile chemical. He dropped a flask containing the toxic substance and smashed it. Before he left the room, he had inhaled noxious vapours of the chemical. Two days later he was admitted to hospital with the following complaints: malaise, somnolence, headache, nausea, back pains, blood in the urine. Blood analysis: erythrocytes 2.7x1012/L, Hb 80 g/L, platelets 120x109/L, leukocytes 3.1x109/L; compensated acidosis (metabolic and renal). The resuls of the special blood biochemistry analysis: an increased concentration of free fatty acid, lipid hydroperoxides, and adenosinephosphate; an elevated total creatinephosphate kinase (CPK) activity and potassium content.
