Due to the negligence of the "I have a date with Spring" crew, the two male and female protagonists in the play were severely burned, and the burn scars entered the public's field of vision for a time. As the media announced the progress of the treatment of Ren Jiayu and Yu Yuming's injuries, people began to have a certain degree of understanding of burn scars, but not comprehensive enough.

Burn refers to a kind of damage caused by flame, hot gas, body, solid or electricity, radiation and chemicals, which acts on the human body. It not only causes serious damage to the body, but also "acts" psychologically and spiritually. The heavy blow is even more miserable for some disabled patients and even loses confidence in life.

If your burns are not very serious, they will not be taken seriously, so the condition will often be delayed. Some patients will often convert mild (shallow) burns into severe (deep) burns, and bring them to patients and health care workers. It is extremely difficult to come. Burning for a long time will leave it difficult to see. If the burn is on the face, hands or joints, it will cause disfigurement, joint dysfunction or deformity. Seriously affect the patient's study, work and life. In addition, the patient's temperament is more irritating. If this method does not work in a short period of time, it will be replaced with another method. It will take a few days to see that there is no effect, and another method will be used. In the long run, various substances will react. , allergies, and long-term formation of systemic infections.

Yu Yuming's burn situation, according to media reports for deep second degree burns, what is the concept of deep second degree burn?

According to the depth estimation of burns, the three-degree four-point method is generally used, that is, first degree burn, shallow second degree burn, deep second degree burn and third degree burn. Severe burns not only damage the skin, but also deep muscles, bones and even systemic changes such as shock infections.

Once burned: the skin at the injured site was mild red, swollen, hot, painful, hypersensitive, and bubble-free;

Shallow second degree burn: the skin of the injured area is severely painful, allergic to the skin, and there is blisters; after the blisters are separated, the wound surface is evenly red, moist, and edematous;

Deep second degree burns: Injured skin is slower, with or without water bubbles, pale base, red spots between them; pain can be felt when plucking;

Third degree burns: skin feels disappear, inelastic, dry, waterless, waxy, yellowed or carbonized; no pain when plucking.

It is easy to form uneven scars due to changes in skin color caused. Burns and burns are high in summer. Because people wear less clothes and expose their skin, especially for children who just learned to walk, their self-protection ability is very poor, their curiosity is very strong, and they are particularly prone to serious burns. Generally speaking, burns are mostly burned. Injury to the dermis, the chance of leaving scars on the skin is nearly 90%. How to effectively prevent burning is the key.

When the skin is burnt, burned, or the like, the dermis tissue defects and body parts caused by collagen are lost, and the organism in the human body cannot completely repair the complex tissues of the dermis and subcutaneous tissues. So when the epidermis is torn and the dermis is injured, the wound can only be repaired by connective tissue.

The collagen fibers that have been neatly and orderly arranged in the dermis begin to shrink, confuse, accumulate, and break, and new capillaries and nerve fibers grow inside the new connective tissue. In this way, the misalignment and rejuvenation of the collagen fibers make the skin after healing uneven, and the blood circulation of the injured skin becomes unstable, and the pigment of the injured skin may be mutated.
