Medical alcohol is not the same as ethanol disinfectant. Ethanol disinfectant refers to a concentration of 75% containing alcohol, while medical alcohol is available in a variety of concentrations. Medical alcohol containing ethanol at 95% is used to wipe UV lamps. Medical alcohol containing ethanol at a concentration of about 75% can be used to kill viruses and can be used for hand disinfection or wiping small areas of objects. Medical alcohol with a concentration of about 40%-50% can be used to prevent bed sores, and a small amount of alcohol with a concentration of 40%-50 can be poured into the hands to massage the patient’s sacro-caudal region to play a role in preventing bed sores. Alcohol with a concentration of about 25%-50% is used for physical cooling because it can increase the heat dissipation of the skin after wiping, but the concentration should not be too high, otherwise it will stimulate the skin.
