The wound caused by accident needs disinfection. What concentration of alcohol should I use?

Now people like sports, especially the student party. When you have nothing to do, you always ask for a game, whether it is basketball or football, you are active enough. And strenuous exercise often comes to us with injuries, which is not very friendly. When it comes to treating wounds, people first think of alcohol, but can alcohol be used to treat wounds? Is it 75% or 95%?

Let's start with 95% alcohol, which is used for some medicinal and other purposes without direct contact, such as planting, disinfection and sterilization of plants, especially crops. Definitely not suitable for treating wounds. Once it is contaminated carelessly, rinse it with clear water immediately, otherwise it will irritate the wound and cause adverse reactions.

So, let's talk about 75% alcohol. This alcohol is softer than 95% of protein. Can be used for sterilization, can penetrate subcutaneous tissue, directly remove germs, and play a role in disinfection and sterilization. But unfortunately, 75% alcohol is not suitable for disinfection and sterilization of wounds, because no matter how alcohol is treated, the "aggressiveness" of alcohol exists, which will stimulate wounds and affect healing. So it is better to treat the wound with iodophor.

So what is the sterilization principle of alcohol? Because the main component of bacteria is protein, and alcohol has the natural function of decomposing protein, which is exactly what you want. Alcohol also has a certain osmotic effect, which can be directly inserted into the heart of bacteria to achieve the purpose of sterilization. So simply speaking, alcohol is not suitable for disinfection of open wounds, but only suitable for disinfection of intact skin. For example, the nurse disinfected the back of our hands during intravenous drip. It is best to disinfect the wound with iodophor.
