The Successful Treatment of High Lethal Dose Paraquat Poisoning With Hemoperfusion

Abstract

Paraquat (PQ), as an herbicide, is mostly used by farmers, especially in the north-west of Iran. Easy access to PQ is the reason for PQ intoxication in farm­ers. However, poisoning with PQ is rare. Most of the PQ-poisoned patients ingest it deliberately and following a suicidal attempt. PQ poisoning treatment has a poor outcome; only a small dose of slightly more than 10 mL PQ could be harmful and damage lungs forever. Under the conditions of no specific clinical feature, proper history, and diagnostic test, diagnosis is usually difficult. The ingestion of PQ in toxic doses could be fatal, destroying the lungs, kidney, heart, gastrointestinal tract, liver, and other organs. To remove PQ from the blood and intoxicants, one of the best recommendations is Hemo­perfusion (HP), as an extracorporeal method. In this case report, according to our treatments, early management of high lethal dose PQ poisoning, especially with HP could reduce the morbidity and mortality rates.
