PARAQUAT POISONING: FROM EMERGENCY CARE TO PROGNOSIS

Of all the herbicides used in agriculture worldwide, Paraquat (PQ) has been shown to be the main responsible for serious poisoning in humans. In studies carried out in recent years, there is a large number of fatalities involving accidental or intentional ingestion by PQ. Given this context, this study seeks to identify, through a review of scientific productions, solutions to the guiding question about what are the emergency care and prognoses that promote a low mortality rate and longer survival in patients intoxicated with PC in the last 20 years. This is integrative research using the inclusion criteria: national and international articles, published in the last 20 years (2000 to 2020) in the SciELO, Pubmed and Cochrane databases in English, Portuguese and Spanish, indexed and published in the databases of full data involving PQ poisoning in adult humans. The results show the existence of high rates of poisoning by PQ. The data were presented in table form where the 23 articles were analyzed and explained in a way where it is possible to observe the use of different therapies that seek to assist in the patient's prognosis. The use of some therapies proved to be more effective than others, but despite the many treatments used over the years, mortality rates are still high. Therefore, further research is needed in the search for the production of effective antidotes and therapies.
