Nitrite poisoning

Introduction to nitrite poisoning Nitrite poisoning refers to the cause of poisoning caused by the consumption of salted meat products with high nitrate or nitrite content, kimchi and spoiled vegetables, or misuse of industrial sodium nitrite as salt. Containing nitrate or nitrite bitter water, after the steamer water, nitrite can oxidize the normal oxygen-carrying methemoglobin in the blood into methemoglobin, thus losing oxygen carrying capacity and causing tissue hypoxia. basic knowledge The proportion of illness: 0.001% Susceptible people: no specific population Mode of infection: non-infectious Complications: agitation, lung failure

Causes of nitrite poisoning

The main causes of nitrite poisoning in daily life are:

1. Misuse of nitrite as salt.

Diagnosis and identification of nitrite poisoning

diagnosis

According to the medical history, clinical manifestations and laboratory data is not difficult to make a diagnosis.

Differential diagnosis

1. Insecticide poisoning: There is a change in urine and a history of exposure to insecticides.

2. Purpura disease: purple plaque appears under the skin, not the lips, fingertips and other purpura, no eating fresh pickled pickles and other medical history.

3. Tripterygium wilfordii poisoning: There is a history of eating food of Tripterygium wilfordii, and abdominal pain is severe.
