Can ears be disinfected with alcohol?

Alcohol has a wide range of uses. Alcohol is actually ethanol, an organic compound that is flammable, volatile, and low in toxicity. Alcohol is also a transparent liquid without any color. If the alcohol purity is very high, it cannot be drunk directly. Alcohol vapor is likely to form an explosive mixture in the air, so everyone must pay attention. So can the ears be disinfected with alcohol?

First, can the ears be disinfected with alcohol? Ethanol disinfectant alcohol can be used to disinfect wounds on human skin. It can kill bacteria in wounds, and you should be especially vigilant against wound infections and inflammations, especially in summer. Disinfecting the wound on the ear with ethanol disinfectant or medical alcohol can kill bacteria and prevent infection.

Second, alcohol with a volume fraction of more than 99.5% is called anhydrous alcohol. Uses in biology: The pigments in chloroplasts can be dissolved in the organic solvent anhydrous ethanol (or acetone), so anhydrous ethanol can be used to extract the pigments in chloroplasts. 95% alcohol is used to wipe UV lamps. This type of alcohol is commonly used in hospitals, but at home it is only used to clean camera lenses. 70% to 75% alcohol is used for disinfection. This is because too high a concentration of alcohol will form a protective film on the surface of the bacteria, preventing it from entering the bacteria, making it difficult to kill the bacteria completely. If the alcohol concentration is too low, it can enter the bacteria but cannot coagulate the protein in their bodies, nor can it completely kill the bacteria. Among them, 75% alcohol has the best disinfection effect. 40% to 50% alcohol can prevent bedsores. The back, waist and buttocks of bedridden patients may develop bedsores due to long-term pressure. If you pour a little 40% to 50% alcohol into your hands and evenly massage the pressure areas of the patient, you can promote local blood circulation and prevent the formation of bedsores. 25% to 50% alcohol can be used to physically reduce fever. Patients with high fever can use it to rub their bodies to reduce temperature. Because wiping the skin with alcohol can dilate the patient's skin blood vessels, increasing the skin's heat dissipation capacity. The alcohol evaporates and absorbs heat, which lowers the patient's body surface temperature and relieves symptoms.

Can the ears be disinfected with alcohol? You can use alcohol to rub it, mainly to prevent local infection. General local skin changes can also be controlled. You can determine whether it is a local skin allergy based on the actual situation, control the inducing factors, and prevent this situation from recurring. Try not to eat spicy and irritating foods.
