How to correctly treat nitrite poisoning?

Nitrite is an industrial chemical. If the human body ingests too much nitrite, poisoning will occur. Nitrite is also produced in overnight dishes and cured meats, so everyone should consume them in moderation. Poisoning patients should be sent to hospital for gastric lavage as soon as possible.

Treatment

1. Oxygen inhalation: Nitrite is an oxidant that can oxidize normal low-iron hemoglobin into high-iron hemoglobin, which loses its oxygen transport capacity and causes tissue hypoxia. Observations showed that the patient had a blue face, cyanotic lips, and blue-purple venous blood, all of which were manifestations of hypoxia, so he was given oxygen immediately.

2. Gastric lavage: If the poisoning duration is short, gastric lavage should be performed in time.

3. Application of methylene blue: It is a specific antidote for nitrite poisoning, which can reduce methemoglobin and restore normal oxygen supply function. The dosage is calculated as 1~2 mg per kilogram of body weight. At the same time, hypertonic glucose can increase blood osmotic pressure, increase detoxification function and have a short-term diuretic effect.

4. Symptomatic treatment: Patients with affected cardiopulmonary function should also receive symptomatic treatment, such as respiratory stimulants, drugs to correct arrhythmias, etc.

5. Nutritional support: After the condition stabilizes, supportive therapies such as energy mixture and vitamin C will be given.
