Symptoms of nitrite poisoning

summary

Nitrite poisoning is common in daily life. It mostly exists in pickled vegetables, especially pickled vegetables with industrial nitrite, overnight vegetables, rotten leaves, meat and other foods added with industrial nitrite. Symptoms of nitrite poisoning, let me tell you.

Symptoms of nitrite poisoning

Symptoms of nitrite poisoning: the patient will feel dizzy, headache, lethargy, stomachache, diarrhea, nausea, vomiting, dyspnea, lips and fingernails, and in severe cases, the skin of the whole body will appear purple (methemoglobinemia). Patients with severe poisoning will also have mental depression, showing slow reaction, unconsciousness, convulsion, coma, respiratory failure, and even death.

Nitrite will directly oxidize hemoglobin in human body to methemoglobin, that is, it contains trivalent iron ions, which makes normal hemoglobin lose the ability to transport oxygen, and eventually lead to severe hypoxia of human tissue, purplish body and other toxic manifestations. Once respiratory failure occurs, it is likely to cause serious consequences of death.

The treatment method after nitrate poisoning: through the use of reducing substances (such as vitamin C) to reduce methemoglobin to normal hemoglobin, increase its oxygen carrying capacity, at the same time reduce the content of nitrite in the body, supplement the body's oxygen content, injection or drip of reducing drugs for treatment. Nitrite poisoning can be divided into acute poisoning and chronic poisoning. Patients with mild symptoms generally do not need treatment, and acute patients should be sent to hospital as soon as possible.
