Emergency Treatment of Sodium Nitrite NaNO2 Poisoning

  Sodium nitrite poisoning is a food safety problem that always scares us. Not only can the mistake of eating illegally added sodium nitrite cause poisoning, but also some of our common foods in daily life may also contain sodium nitrite, and some poisoning is long-term slowly accumulated, such as fresh leaf vegetables, pickled vegetables, bitter well water, eye meat products, etc.

  Nitrite poisoning has a certain incubation period, and the incubation period of poisoning caused by ingestion of pure nitrite is generally 10- 15 minutes. For those who eat a large number of vegetables or unpickled vegetables, the incubation period is generally 1 to 3 hours, and the onset of the disease is as long as 20 hours. The mild manifestations of poisoning include headache, dizziness, weakness, chest tightness, shortness of breath, lethargy, palpitation, nausea, vomiting, abdominal pain, diarrhea, and cyanosis of the lips, nails and skin and mucous membranes of the whole body. In severe cases, there are symptoms such as slow heart rate, irregular heartbeat, coma and convulsions, and often death due to respiratory and circulatory failure.

  Emergency treatment of sodium nitrite poisoning methods are:

1. Oxygen: sodium nitrite mainly through oxidation to reduce the oxygen content of the human body, to carry out oxygen treatment as soon as possible;

2. Gastric lavage: the poisoning time is short, it is also recommended to timely vomiting, gastric lavage and diarrhea to eliminate the poison;

3. Detoxification: methylene blue is a special antidote for nitrite poisoning, which can restore methemoglobin and restore normal oxygen delivery function;

4. Symptomatic treatment: for patients with cardiopulmonary function affected, there should be symptomatic treatment;

5. Nutritional support: After the condition of severe patients is stable, support therapy such as energy mixture and vitamin C can be used.

  Sodium nitrite poisoning often makes us not see the danger in life. Consumers should use protection when eating out and drink more water and milk, which can also be combined with vitamins and poison prevention. Vegetables and other ingredients should be cleaned before eating. People should eat less pickled food and brine flavor, and the harm of sodium nitrite poisoning can be reduced.
