Can 75-degree alcohol be used to wipe wounds?

Alcohol is a very important disinfectant. It is basically present in our daily life because alcohol can help us treat bacteria in some wounds and kill the bacteria completely. Too low alcohol concentration may cause bacteria to enter our body directly, so everyone should be careful when choosing alcohol. Here is some relevant knowledge about alcohol.

The main component of medical alcohol is ethanol. Medical alcohol is mainly used for disinfection. In daily life, it is common for some people to use medical alcohol to scrub wounds in order to achieve the purpose of sterilization and disinfection. It is worth noting that the alcohol purchased in pharmacies comes in two concentrations: 75% and 95%, and the uses of these two concentrations of alcohol are different. The main ingredients of medical alcohol are

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.

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 and increase the skin's heat dissipation capacity. Its volatility can also absorb and take away a large amount of heat, thereby relieving symptoms. But the alcohol concentration should not be too high, otherwise it may irritate the skin and absorb a lot of moisture from the epidermis.
