Decontamination

After paraquat ingestion, early gastrointestinal decontamination is essential. Patients must be alert and cooperative, and able to protect their airway, or be intubated, to receive gastrointestinal decontamination. If the patient is intubated, administer gastrointestinal decontamination via a nasogastric or orogastric tube—confirm correct placement of the nasogastric or orogastric tube beforehand.
