summary

Nitric acid 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.

Does nitric acid harm poisoning symptoms?

The patient will feel dizziness, headache, tiredness, stomachache, diarrhea, nausea, vomiting, dyspnea, lips, nail caps, and even purple skin (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.

Through the use of reducing substances (such as vitamin C) to reduce methemoglobin to normal hemoglobin, improve its oxygen carrying capacity, reduce the content of nitrite in the body, supplement the body's oxygen content, 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.
