Why do wounds become inflamed? When the human body has a wound, it will become inflamed, red and swo

There are generally two causes of wound inflammation, one is aseptic inflammation, which is mostly caused by tissue necrosis; Another condition is a bacterial infection. The former generally has a large amount of exudate, and in the latter case, suppuration, both of which require dressing changes. It may also be necessary to use medications**.

All bacteria that cause wound infections are local changes and systemic poisoning caused by invasion of tissues. However, tetanus bacillus is different from other pathogenic bacteria, regardless of the group or the exotoxin it produces, it does not produce obvious pathological changes in the wound, and the onset caused by the secretion and diffusion of toxins throughout the body is highly viulent and has a special affinity for nerves, and is distributed in the spinal cord and brainstem after absorption, which is easy to endanger life.

There are dirty things or bacteria in the wound that we can't see, plus the weather is hot, our wound is not directly exposed to the air without the protection of **, just like raw meat, the phenomenon of decay will occur, and these rotten phenomena are what we call inflammation.

Because bacteria enter the wound at the time of injury, there are phagocytes in the inner layer to prevent bacteria from entering. While it kills bacteria, it releases a substance that will make ** inflamed and swollen as a reminder that the wound needs to be treated.

Based on your description, consider the possibility of local bacterial infection of the wound. After the body is injured, germs can invade from the wound, and the tissue cells will secrete histamine, resulting in increased capillary permeability, and the water in the plasma will penetrate into the tissues and cause swelling, resulting in redness.

Eat lightly, avoid spicy foods, and keep the area clean. Generally speaking, small wounds will not be red and swollen again in three or four days. If it is always red and swollen, you should go to the hospital for disinfection.

**It is a very ingenious set of "coats" of the human body, which can block the invasion of bacteria. **Injury, bacteria take advantage of the weakness and release harmful substances, causing local blood vessels in the human body to dilate, blood flow to speed up, **local redness; As the blood vessels dilate, plasma leaks out of the blood vessels and flows into the surrounding tissues, causing the tissues to swell.

Under normal circumstances, the body's own defense system will clean up in time when the viruses and bacteria that invade the body are found to protect the human body from harm, and when the surface is injured, the body's immunity will decline significantly, which can easily cause bacterial invasion or virus infection, if you do not pay attention to the care of the wound, it will cause inflammation and infection of the wound.

After the injury, there is no detailed disinfection treatment, which leads to the wound being exposed to too many bacteria, so that the local ** is infected, which leads to a decrease in the local antiviral ability, and the germs will take the opportunity to enter the body from the injured area, causing infection and inflammation of the affected area; In addition, water on the wound can also cause bacterial infection.

The nature of inflammation is defensive, as long as the body's resistance is good, it can be controlled in a timely and reasonable manner, and in medicine, whether the inflammation subsides is the main indicator to judge the effect. Principles for the treatment of wound infection: to change dressings in time, and disinfection should follow the principle of sterilityWhen changing dressings, it is necessary to remove and drain the wound secretion as much as possible, and remove necrosis and necrotic tissue on the wound surface.

For patients with obvious fluctuation sensation under the skin or in the wound, it is generally considered that there may be an abscess inside, and the wound sutures should be removed in time, the necrotic material inside should be cut and drained, and the dressing should be changed regularly when necessary, so that the wound can heal better.

It is because after the inflammation, some changes will occur in the epidermis, plus there is some inflammation, which will lead to inflammation.

Because after the human body has a wound, some bacteria will breed, and the bacteria will cause inflammation, redness and swelling. That's why the wound becomes inflamed.

Because after the wound appears, there will be some bacterial growth, and bacterial growth will cause unhealthy **, so it will become inflamed.

Because the wound does not heal on its own, red blood cells accumulate near the wound, causing the wound to become inflamed and swollen.

I think it's due to my own constitution, because after a wound, inflammatory factors will appear, which will eventually lead to inflammation.
