Why does medical hydrogen peroxide foam when removing blood?

Hydrogen peroxide foams because it contains an enzyme called catalase in the blood and cells. Because a cut or abrasion has both blood outflow and damaged cells, large amounts of catalase can accumulate around the wound.

When catalase comes into contact with hydrogen peroxide, it converts hydrogen peroxide (H2O2) into water (H2O) and oxygen (O2).

2h2o2 --2h2o + o2

Catalase is extremely efficient in carrying out the above reactions, with 200,000 reactions per second. The bubbles seen in the bubble are pure oxygen bubbles produced by catalase. Try adding a little hydrogen peroxide to a cut potato, and the same phenomenon can be observed, for the same reason, catalase in damaged potato cells reacts with hydrogen peroxide.

Hydrogen peroxide does not create bubbles in the bottle or on our ** because there is no catalase to facilitate the reaction. Hydrogen peroxide is stable at room temperature.

Despise the upstairs, nonsense.

Hydrogen peroxide is also called hydrogen peroxide.

Peroxide is unstable and will decompose into water + oxygen.

When stored normally, this process is still relatively slow, and when hydrogen peroxide comes into contact with **, it will accelerate its decomposition (quite quickly) and you will see a large number of bubbles coming out

In medicine, hydrogen peroxide is often used to disinfect open wounds, and today I fell and why there was white foam when disinfecting with hydrogen peroxide? Do you want to wipe off the foam of hydrogen peroxide?

Hydrogen peroxide has strong oxidation, disinfection with hydrogen peroxide is because of its oxidation, in the process of disinfection, catalase will accelerate the decomposition of hydrogen peroxide, producing a large amount of oxygen and water, thus forming a white foam.

It is recommended to wipe it off. Hydrogen peroxide is generally only used for open wound disinfection, which has a certain corrosive effect on normal ** tissues, and it is normal to disinfect white foam with hydrogen peroxide, but it may also cause pigmentation of other damaged tissues, so it is recommended to wash with normal saline or sterile distilled water in time after using hydrogen peroxide, and pay attention not to rinse with tap water.

After hydrogen peroxide is applied, it is generally recommended to clean.

Hydrogen peroxide is used to coat the wound just for disinfection, after the elimination of poisoning, it is generally recommended to use the normal saline or sterile water of the mountain wheel nucleus for Tongzhen cleaning, otherwise hydrogen peroxide is easy to cause ** pain to the wound, after rinsing the wound, it can be disinfected regularly with iodine.

When hydrogen peroxide is used for disinfection, it has a strong oxidation effect, and the concentration of medical hydrogen peroxide is generally equal to or less than 3%, and there will be a burning sensation when wiping the wound surface, and the surface is oxidized to white or bubbles, although it will be painful, but its disinfection effect is better, which is normal, and it will be relieved by rinsing it with normal saline.

The invasion route of hydrogen peroxide is normal contact, inhalation, ingestion, etc., high concentration of hydrogen peroxide has strong corrosiveness, hydrogen peroxide is generally not used for disinfection without open wounds, which will lead to pigment deposition; After inhalation, it will have a strong ** sex on the respiratory tract; Oral poisoning may cause abdominal pain, chest pain, dyspnea, vomiting, increased body temperature and other symptoms, if hydrogen peroxide is used improperly, it will cause certain damage to the human body, it is recommended to use it under the guidance of a doctor.
