Study of laboratory profile in patients with aluminium phosphide poisoning in the southwest of Iran from 2010 to 2015

Abstract

Introduction : Aluminium phosphide or rice tablet is one of the most common pesticides around the world. The substance releases phosphine gas in the presence of water, steam or stomach acid which can lead to poisoning. Phosphine poisoning is more about suicide the number of which is increasing day by day. Two-thirds of patients lose their lives. The aim of this study was to evaluate the data on the clinical epidemiology and laboratory changes in patients poisoned with rice tablets. Material and methods : A total of 23 patients poisoned by aluminium phosphide who referred to Ahvaz Razi hospital within the period of 2010–2015 were studied. The data were analyzed using descriptive statistics and statistical tests. Results : The mean age of the patients was 27.2 ±7.3 years and 60.9% of the patients were male. 8.7% of the patients had hyponatremia and 21.7% of the patients had hypokalemia. In the majority of cases the amount of sodium and potassium was normal. 91% of patients had acidosis and serum bicarbonate was reduced in the majority of cases. The average interval between poisoning and admission was 1.48 ±0.76 hours. Conclusions : The pattern to change the electrolytes and other laboratory factors could be a good marker of the severity of the poisoning and the clinical conditions of the patient, which requires more specific research to prove the process.
