Strong alkali poisoning

Introduction to strong alkali poisoning Strong alkalis include sodium hydroxide, potassium hydroxide, sodium hypochlorite, sodium oxide, potassium oxide, and sodium carbonate, potassium carbonate, calcium hydroxide, calcium oxide, ammonium hydroxide, and the like which are less corrosive. The bleaching powder contains 3% to 6% potassium hypochlorite. The strong base compound is widely used in detergents, ditch cleaners, polishes, paint removers and perm agents for daily use. Pediatric poisoning is mostly caused by misuse. basic knowledge The proportion of illness: 0.008%-0.01% Susceptible people: no specific population Mode of infection: non-infectious Complications: pneumonia, pleurisy, pericarditis, shock, coma, pulmonary edema

Causes of strong alkali poisoning

Cause:

Poisoning is caused by accidental ingestion, skin contact burns, and eyes splashing into burns.

Strong base poisoning prevention

The production unit should reform and improve the production process to reduce the phenomenon of running, leaking and escaping of corrosive agents. Workers should observe the operating procedures and wear protective clothing, protective gloves, etc. when performing related work. Skin contact should immediately flush the contact surface with plenty of water. Inhalers should leave the poisoned environment in time and transfer to fresh air.

1. Reform and improve the production process to reduce the phenomenon of running, leaking and taking off of corrosive agents.

2. Strengthen publicity, abide by operating procedures, and strengthen personal protection.

3. In the event of an accident, rinse thoroughly.

Strong base poisoning complications Complications pneumonia pleurisy pericarditis shock coma pulmonary edema

Oral poisoning, combined with aspiration pneumonia, mediastinal inflammation, pleurisy, pericarditis, glottic edema and suffocation, shock and coma, and even death.

Inhalation poisoning, stagnation of hemoptysis and necrotic tissue may occur in tracheal and bronchial mucosal tissue necrosis. Pulmonary edema, shock and coma, and even death may occur if rescued in time.

Eye burns, heavy can cause blindness.

Symptoms of strong alkali poisoning Common symptoms Difficulty breathing edema coma severe headache Digestive tract stenosis Rushing renal failure Blisters suffocation

After taking it, it causes oral, pharyngeal, esophageal and stomach burning pain, abdominal cramps, runny nose; vomiting blood content of the stomach is strong alkaline; discharge of bloody mucus feces, mouth, throat visible erosion of the wound, first white , then turned red or brown, severe cases of laryngeal edema, asphyxia, pulmonary edema, shock, esophageal and gastric perforation, can cause digestive tract stenosis in the later stage, when the solid alkali is ingested, the mouth can be no obvious damage, and the esophagus and stomach corrosion Very heavy, after the absorption of poison, alkalosis occurs, sick children have severe headache, low-calcium hand, foot and ankle, coma, etc. Others may have liver, kidney and other internal organs damage, occasionally acute renal failure, the main symptoms of inhalation poisoning symptoms For severe cough, difficulty breathing, edema of the throat, pulmonary edema, and even suffocation, the contact is mainly local redness, blisters, erosion, ulcers and so on.

Inspection of strong alkali poisoning

The poison of the deduction can be detected in the vomit or the cleaning solution after poisoning. Gastric acid pH (pH) check: normal gastric juice pH is 0.9 ~ 1.8 typical local corrosion, clinical manifestations of systemic poisoning. Among the organic strong bases, the organometallic compounds are most basic, such as organometallic lithium compounds (such as butyl lithium, lithium diisopropylamide, benzyl lithium, etc.), Grignard reagents, alkyl copper lithium, and the like. This is followed by sodium alkoxide or potassium alkoxide (such as sodium methoxide, sodium ethoxide, potassium ethoxide, sodium t-butoxide, etc.). The above organic strong base is more alkaline than sodium hydroxide. Bismuth and quaternary ammonium bases are also organic strong bases, and their basicity is comparable to that of sodium hydroxide.

Diagnosis and identification of strong alkali poisoning

Identification of consciousness, breathing, and circulatory disorders caused by non-organophosphorus and organophosphorus poisoning.
