An analysis of ethylene glycol acute intoxication treatment results was performed in a group of 36 patients hospitalized within a five year period. Mean serum and urine glycol concentrations in the analyzed population ranged from 0-851 mg/dl (mean = 130 mg/dl) and from 12.4 to 930.0 mg/dl (mean 333 mg/dl), respectively. At the time of admission to the clinic 15 of 36 patients were deeply unconscious and mean acid-base balance values were as follows: pH 6.99, pCO2 16.7 mmHg, pO2 140.1 mmHg, HCO3 6.36 mmol/l, BE -29.6 mmol/l. Because of respiratory failure 21/36 patients (58.3%) required controlled ventilation and 24/36 (66.7%) underwent dialysis. Sixteen patients (44.4%) developed acute renal failure. Mean hospitalization period was 16 days (1-53). Eighteen patients (50%) died. The direct death mechanism in 15 patients (83.3%) was asystolia and in the remaining individuals other circulatory disturbances. The main reasons of high mortality rate were multiple organ damages secondary to severe metabolic acidosis.
