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.

Cause of nitrite poisoning: nitrite will directly oxidize hemoglobin in human body to methemoglobin, that is, it contains trivalent iron ions, which makes the normal working hemoglobin lose the ability to transport oxygen, and eventually lead to severe hypoxia in human tissues, purplish in the whole body and other poisoning manifestations. Once respiratory failure occurs, the body will be poisoned, It is likely to cause serious consequences of patient 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.
