What purpose can bandaging achieve

It is very common to get injured by bumps and bruises. There are many reasons for injuries, such as being hit, falling, accidental abrasions, etc. If there is a wound, it needs to be bandaged, especially if the wound is deep. If the wound is not bandaged, it will affect the healing of the wound and may also cause infection, which is not good for health. It is very important to bandage the wound correctly. What purpose can bandaging achieve?

What is the purpose of bandaging?

The purpose of bandaging is to protect wounds and injured surfaces, reduce infection, and relieve pain; pressure bandaging has a hemostatic effect; bandaging is required when splinting fractured limbs to reduce secondary injuries and facilitate transportation to the hospital. When bandaging wounds on site, you can use local materials, such as towels, handkerchiefs, and strips of torn clothes.

How to clean a wound

Before cleaning the wound, put the patient in an appropriate position to facilitate the rescuer's operation.

If the surrounding skin is too dirty and mixed with mud, etc., it should be washed with clean water first, and then the skin around the wound should be disinfected with 75% alcohol or 0.1% Sanisol solution (a commonly used disinfectant). The skin around the wound should be disinfected from the inside to the outside, starting from the edge of the wound and gradually expanding the disinfection area to the surrounding area. The closer to the wound, the cleaner it is. If you use iodine to disinfect the skin around the wound, you must then wipe it off with alcohol. This "deiodine" method is to avoid iodine burning the skin. It should be noted that these disinfectants are highly irritating and should not be applied directly to wounds.

The wound should be gently scrubbed with a cotton ball dipped in saline. Make your own saline solution by adding 9 grams of salt to 1000 ml of cold boiled water.

When cleaning and disinfecting the wound, if there are large and easy-to-remove foreign objects, they can be removed as appropriate; deep, small and difficult-to-remove foreign objects should not be removed forcibly to avoid bringing bacteria into the wound or increasing bleeding. If there is a foreign object that has penetrated into the body cavity or near a blood vessel, do not remove it rashly to avoid damaging the blood vessel or internal organs and causing danger. No on-site treatment is required.

After the wound is cleaned, different treatments can be performed according to the situation. If it is a small wound on the mucous membrane, you can apply mercurochrome or gentian violet, or sprinkle anti-inflammatory powder, but do not apply the above drugs on large wounds.

If there are some particularly serious wounds, such as prolapse of internal organs, the patient should not be sent back to avoid serious infection or other accidents. In principle, you can wrap it with a large sterilized gauze or clean cloth, then put a bowl or small basin that has been disinfected by wiping with alcohol or boiling on it, and wrap it with a belt or triangular towel.

How to bandage a wound

After the wound has been cleaned, it should be bandaged. Bandaging has the purpose of protecting wounds, applying pressure to stop bleeding, reducing infection, relieving pain, and fixing dressings and splints. When bandaging, you should be quick, accurate, gentle and firm. Fast, that is, the movements are agile and quick; that is, the location is accurate and strict; light, that is, the movements are gentle and do not hit the wound; firm, that is, the bandage is firm, not too tight so as not to affect the blood circulation, and not too loose so as not to fall off the gauze.

There are different methods for bandaging wounds in different parts of the body. Here we introduce several commonly used bandaging materials and methods.

The most commonly used bandaging materials are roll bandages and triangular bandages, which can be replaced by corresponding materials at home. A roll bandage is made of gauze rolled up, usually 5 meters long. A triangular bandage is a square piece of gauze cut diagonally to form two triangular bandages. The triangular bandage is flexible to use, has a large bandaging area, and can be applied to all parts of the body.
