Blood lavage is an important method of treating paraquat poisoning, but whether it can be completely cured has a greater relationship with the dose and time of paraquat taken by the patient and whether other resuscitation measures are carried out. Blood irrigation can adsorb paraquat that has entered the bloodstream and reduce the harm to various organs, but whether it can cure paraquat poisoning dose, time of taking and so on have a greater relationship, if the amount of taking is relatively large, the blood irrigation time is late, the probability of cure will be very low. Taking a small amount of early and timely vomiting, with blood perfusion can increase the probability of cure, but due to paraquat no special effect antidote, there is still a greater probability of leading to the death of the patient. Therefore, paraquat poisoning should pay the most attention to prevent the accidental consumption of paraquat.
