ammonia gas is a kind of very useful, a lot of places can use ammonia, so what happens if accidentally inhaled ammonia?
Ammonia has corrosive and stimulating effects on skin tissues in contact, which can absorb moisture in skin tissues, denature tissue proteins, saponify tissue fat, and destroy cell membrane structure.
Ammonia has a very high solubility, so it mainly irritates and corrodes the upper respiratory tract of animals or human beings, and is often adsorbated on the skin mucous membrane and eye conjunctiva, resulting in irritation and inflammation.
Can paralyTIC respiratory cilia and damage mucOUS membrane epithelium organization, MAKE PATHOGENIC microorganism invades easily, WEAKEN human BODY TO the RESISTANCE OF the disease.
Ammonia is usually inhaled into the human body as a gas. After being inhaled into the lungs, ammonia can easily enter the blood through the alveoli, bind to hemoglobin, and destroy oxygen transport function.
A small part of the ammonia that enters the alveoli is neutralized by carbon dioxide, the rest is absorbed into the blood, and a small amount is excreted through sweat, urine or breathing.
Ammonia poisoning is mainly seen in ammonia production, transportation, storage, use, such as pipeline, valve, storage tank damage, leakage caused.
Accidental ingestion of ammonia is rare.
1. Irritation reaction: only transient eye and upper respiratory irritation symptoms, no obvious positive signs in the lungs.
2. Mild poisoning: inhaled more ammonia, may appear tears, sore throat, hoarseness, cough, expectoration, and can be accompanied by mild dizziness, headache, fatigue, eye conjunctiva, nasal mucosa, pharynx congestion edema, lung dry rales.
3. Moderate poisoning: after inhaling high concentration of ammonia, pharyngeal burning pain, hoarseness, severe cough, sputum production, sometimes with bloodshot sputum;
Chest tightness, dyspnea, often accompanied by dizziness, headache, nausea, vomiting, loss of appetite, fatigue, etc., conjunctival and pharyngeal obvious congestion, edema, laryngeal edema, breathing rate, mild cyanosis.
Dry and wet rales in the lungs.
4. Severe poisoning: after inhaling high concentration of ammonia for a long time, frequent intense cough, cough a lot of pink foamy sputum, sometimes pouring out of the nostrils;
At the same time, chest tightness, dyspnea and other manifestations.
The onset time of pulmonary edema is early, the shortest time is 15 minutes, generally in 1-6 hours, some cases of pulmonary edema 30 hours after poisoning, and often accompanied by laryngeal edema, palpitation, irritability, nausea, vomiting or delirium, coma, shock, myocarditis or heart failure.
3 to 7 days after poisoning, the trachea and bronchial mucosa necrosis, exfoliation, block, strip, or dendritic, the same patient can be interrupted several times out of the exfoliated trachea or bronchial mucosa.
Often complicated by secondary infection, high temperature.
Oral and pharyngeal mucosa hyperemia, edema, erosion, white pseudomembrane formation, respiratory distress, obvious cyanosis.
Lungs full of dry, wet rales.
