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. After nitrite poisoning, mild vomiting and diarrhea, severe coma or even death, daily we often eat cabbage, spinach, leek, etc. to be boiled before eating, do not pick wild vegetables, start from the details of daily life, from the action and thought to attract everyone's attention. So what are the symptoms of nitrite poisoning? Let's have a specific understanding.

Symptoms of nitrite poisoning

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 treatment after acid salt poisoning: through the use of reducing substances (such as vitamin C) to reduce methemoglobin to normal hemoglobin, increase its oxygen carrying capacity, reduce the content of nitrite in the body, supplement the oxygen content in the body, inject or drip 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.

Third: the cause of nitrite poisoning: nitrite will directly oxidize the hemoglobin in the human body to 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, nitrite will cause severe poisoning, It is likely to cause serious consequences of patient death.
