Potassium permanganate crystals adhering to the skin or mucous membranes

Introduction Potassium permanganate is a strong oxidant. It has a low concentration of disinfection and astringent effect, and a high concentration has irritating and corrosive effects. Pediatric poisoning is often caused by the ingestion of its crystals as a sugar or by accidental consumption of its solution; occasionally, in the rescue of poisoning, the application of a high concentration of gastric lavage results in the attachment of potassium permanganate crystals to the skin or mucosa. 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.

Cause

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.

an examination

Diagnosis based on symptoms after 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.
