What symptom does nitrite poison have

First: 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 show a degree of purple (methemoglobinemia). Patients with severe poisoning will also have mental depression, showing slow reaction, unconsciousness, convulsion, coma, respiratory failure, and even death.

Second, the cause of nitrite poisoning: nitrite will directly oxidize the hemoglobin in the human body into methemoglobin, which contains ferric ions, so that the normal working hemoglobin loses the ability to transport oxygen, and eventually leads to severe hypoxia in human tissues, body purplish and other poisoning manifestations. Once respiratory failure occurs, the body will be poisoned, It is likely to cause serious consequences of patient death.

Third: the treatment of nitrate poisoning: through the use of reducing substances (such as vitamin C) to reduce methemoglobin to normal hemoglobin, increase its oxygen load, reduce the content of nitrite in the body, supplement the body 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.
