Resumen
El Paraquat es un herbicida bipiridílico que se presenta en forma líquida en concentraciones del 20% para uso agrícola. Su nombre químico es eI 1-1´-dimetil-4-4- bipiridilo, con el nombre comercial de Gramoxone. La intoxicación por Paraquat tiene una tasa de mortalidad elevada. El pulmón es el órgano diana en la intoxicación por Paraquat y la insuficiencia respiratoria con fibrosis pulmonar aguda es la causa más común de muerte. Interesa conocer cuál es la afectación del Paraquat en el sistema nervioso central. Dada su alta toxicidad, si la dosis es letal la mayor de los pacientes mueren en 48 horas y no se observan efectos neurológicos.
