AIM To evaluate various schemes for paraquat poisoning and different variables that influence the outcome of acute paraquat *** In a cross-sectional study, the information about all cases of acute paraquat poisoning who were admitted to teaching hospitals affiliated to Shiraz University of Medical Sciences, in a five year period(September 2010 to September 2015) were evaluated. The variables included: Demographic data, medical assessment, therapeutic options, laboratory findings, and the outcomes. Data were analyzed using SPSS, version 22. Significant difference between groups was tested using t-test for continues outcomes and χ~2 test for categorical. The significance level was considered to be P < 0.05. RESULTS A total of 104 patients(66.3% male) were evaluated. The mean age of the female patients was 22.81 ± 9.87 years and the male patients' was 27.21 ± 11.06 years. Ninety seven(93.3%) of all the cases were suicide attempts with mortality rate of 43.2%. Despite the necessity for emergency hemodialysis during the first 6 h of intoxication, none of the patients had dialysis during this time. Immunosuppressive and corticosteroid medications were not administrated in adequate dosage in 31.1% and 60% of the patients, respectively. Ingestion of more than22.5 cc of paraquat and increase in creatinine level were the most important predictors of *** Treatment should start immediately for these ***, creating a clinical guideline according to the findings can have an impact on the treatment procedure which seems to be necessary.
