Potassium permanganate poisoning

Introduction to potassium permanganate poisoning Potassium permanganate is a commonly used medicine for disinfection and gastric lavage, but if it exceeds the prescribed amount, external disinfection will burn wounds and mucous membranes; when gastric lavage is used (prescribed amount is 1:2000-1:5000 concentration), it will cause stomach Mucosal ulcers, erosions. If you accidentally take a high concentration of potassium permanganate solution or powder 3-10 grams, you can die of poisoning. Therefore, care must be taken. basic knowledge The proportion of illness: the incidence rate is 0.005% Susceptible people: good for children Mode of infection: non-infectious Complications: pneumonia

Causes of potassium permanganate poisoning

Cause of disease

Potassium permanganate misappropriation history. The lethal dose is 3 to 10 g.

Pathophysiology

Potassium permanganate is a strong oxidant. Low concentration has disinfection and astringent effect. High concentration has stimulating and corrosive effects. Pediatric poisoning is often caused by eating crystals as sugar or ingesting its solution. Occasionally, it is saved. Poisoning is caused by the use of a high concentration solution for gastric lavage during poisoning.

Potassium permanganate poisoning prevention

1. Drink egg white, milk, glutinous rice flour, rice porridge, noodle soup, etc. to protect the stomach and mucous membranes.

2. Take a large amount of diluted vitamin C solution immediately after poisoning. Because vitamin C is a reducing agent, it is a special antagonist.

3. Wash the stomach repeatedly with water or 0.5% activated carbon solution until the contents of the washed stomach are colorless.

Complications of potassium permanganate poisoning Complications pneumonia

Severe can lead to suffocation and pneumonia.

Symptoms of potassium permanganate poisoning Common symptoms Nausea skin or mucous membrane attached... Diarrhea Abdominal pain Breathing difficulty Blood pressure Drops Muscle muscle tension High muscle fiber tremor Hand tremor

1. The symptoms of oral poisoning vary with the size and concentration of the dose. If you eat 1% of the solution, the sick child has mouth, burning sensation in the throat, runny nose, nausea, vomiting, abdominal pain, diarrhea, etc. The oral mucosa and teeth are brownish black.

2, can also occur gastrointestinal bleeding, necrosis, severe abdominal pain, bloody diarrhea, and even the symptoms of perforation of the digestive tract and peritonitis, manganese absorption can cause paresthesia, loss of orientation, tremor tremor, weak and fast pulse, blood pressure, Even mental disorders and circulatory failure occur. In the case of kidney damage, proteinuria and hematuria may occur, and blood potassium may be elevated, and potassium permanganate crystals may be attached to the skin or mucous membranes, which may be corroded into deep ulcers.

Examination of potassium permanganate poisoning

1, necropsy can be seen in the oral cavity, tongue, pharyngeal congestion and edema gastrointestinal mucosa corrosive pathological changes, severe cases of sac sac mucosa most of the corrosion, erosion and shedding.

2, heart, kidney have different degrees of damage, chronic poisoning can cause encephalitis or pneumonia.

Diagnosis and identification of potassium permanganate poisoning

Mild poisoning

Affirmed increased muscle tone;

Although the increase in muscle tone is not certain, but the fingers have obvious tremors, and the sputum reflexes; there are changes in mental emotions such as easy excitement, emotional instability, and lack of interest in things around.

Severe poisoning

One of the following conditions can be diagnosed as severe poisoning:

Obvious extrapyramidal damage

The performance of Parkinson's syndrome: increased limb muscle tension, accompanied by static tremor, can lead to gear-like rigidity; can appear in the finger or rotation test is not flexible, inaccurate, closed eyes difficult to sign positive, speech disorder , or abnormal gait, difficulty in retreating and other movement disorders.

Toxic psychosis

There are significant changes in mental emotions, such as apathy, unresponsiveness, involuntary crying, obsessive attitudes, impulsive behaviors, etc.
