IntroductionAcute paraquat (PQ) poisoning continues to be a major public health concern in many developing countries. This study was designed to evaluate the data on cases of acute PQ poisoning and compare the different variables between survivors and non-survivors.MethodsAll patients of PQ poisoning who were admitted to the poisoning emergency department during the past five years were retrospectively evaluated. The different variables that were compared between survivors and non-survivors included age and gender, the time from ingestion of PQ to hospital admission, the amount of PQ ingested, occurrence of vomiting after ingestion, the time from hospital admission to initiation of haemodialysis, the length of hospital stay and the outcomes.ResultsA total of 29 patients were evaluated. The in-hospital fatality rate was 55.2 percent. No significant differences were observed between survivors and non-survivors with regard to the patient characteristics. Most of the patients who died had ingested more than 40 mg/kg of 20 percent PQ (62.5 percent). There was a correlation between the outcome of patients and vomiting (p-value is 0.05; correlation coefficient is 0.45) and age (p-value is 0.013; correlation coefficient is 0.56).ConclusionA large amount of ingested PQ, vomiting and age may be important variables to consider in association with the high fatality rate of PQ poisoning.
