ABSTRACT

Acute poisonings with ethylene glycol pose real challenge in the clinical toxicology. The main objective of this study is an analysis of clinical features and identification of prognostic factors in poisoning with ethylene glycol of patients hospitalized in the Toxicology Unit in the years 2000-2009. The medical records of the patients were identified and separated. In the years 2000-2009, 102 patients were hospitalized due to ethylene glycol poisoning, what accounted for 0.38% of total admissions to the unit (26.801 hospitalized people). The mean age of patients amounted 48.05 +/- 12.55 years, the history positive for chronic alcohol abuse was present in 63 (61.76%) cases. Mean values of ethylene glycol concentration were as in serum 173.14 mg/dl, in urine 6576.46 mg/l. Patients condition on admission varied, with 63 (61.76%) cases described as the severe state. The most frequently noted pathologies were consciousness disturbances and tachycardia. 14 patients died within the analysed group and 63 (61.76%) developed single or multiorgan complications in the course of disease. The most commonly encountered complication were acute renal failure, anaemia, pneumonia and central nervous system damage. Such parameters as BE and HCO3 measured on admission should be considered as the prognostic factors, determining the course of the disease and the outcomes of treatment. Poor prognosis may be associated with such clinical features on admission, as respiratory and circulatory disturbances and cerebral sequelae. The importance of acute poisoning of ethylene glycol is determined both by high frequency of immediate life threatening conditions and by the risk of complications leading to permanent organs damage.
