Does it hurt to apply iodine to the wound?

Povidone-iodine has a very good bactericidal effect, so it is also a bactericidal drug frequently used in the medical field. Before people undergo surgery or receive injections or infusions, doctors and nurses must wipe the patients with iodine, as this can effectively prevent germs from invading the patient's body. Since alcohol also has a good bactericidal effect, but wiping the wound with alcohol will make people feel pain. If iodine is used to disinfect the wound, will it make people feel pain?

If you need to disinfect a scratch, should you choose iodine or alcohol?

Both iodine and alcohol have disinfecting effects. Iodine tincture is made by dissolving iodine and potassium iodide in 2 percent alcohol. It is mainly used for disinfection of wound surfaces. It is easy to use and has no irritating smell. It can kill hundreds of germs. Moreover, it has little toxicity to the human body and is not likely to cause allergies. Alcohol has great penetrating power and can penetrate into the interior of bacteria and kill them. However, it has very high requirements for concentration, and different concentrations have different effects. If the concentration is too low, the bacteria cannot be killed. The alcohol content must be more than 70% to be used for disinfection, so it is difficult for ordinary families to master this ratio and it is also troublesome to use. Therefore, for abrasions, you only need to disinfect the surface. Using iodine tincture is convenient and safe.

The difference between iodine and alcohol disinfection

To sum up, iodine tincture is mainly used for disinfection of wounds, but iodine tincture is also a toxic drug. Although its toxicity is very low, it should be avoided when using it on a large area. Alcohol is mainly used for disinfection in hospitals, and it has a stimulating effect. It is quite painful to wipe wounds, so it is best not to use alcohol to disinfect skin that has trauma. Moreover, it is not suitable for some people who are allergic to alcohol.

You can prepare your own disinfectant at home, iodine tincture will do. Alcohol is easy to evaporate and difficult to preserve, and the disinfecting effect of alcohol will be greatly reduced when the concentration is reduced.
