First of all, don't deal with the following situations by yourself: bleeding, possible fracture, suppuration, redness, swelling, heat and pain in two or three days, and other situations that you find unbearable or can't wait with confidence ... The following experience is limited to hand strain caused by common paper, scratches and other small wounds that you don't know how to appear ... Besides, the scar constitution can be bypassed, and there is no way. You know, what are the factors that determine the ugliness of the wound: 1, and the smoothness of the wound. The flatter the wound, the more aligned the two sides, and the easier it is to grow. Therefore, a side injury must grow better than a tear, silly women. So it will be easier to scratch the kraft paper, and the edge of the paper is like a knife. Of course, you have no choice. 2. Growth rate. The child's wound can heal without seeing it at all. I can't help it Human cells are as fast and as good as they are. We can't change our age, but we can: if we have a choice, some operations such as plastic surgery should be done as early as possible; Vitamin A can promote cell renewal and can be used locally after wound healing. Wounds that are too wet or too dry will not grow quickly. Therefore, white skin can't be soaked and dead skin can't be dried. 3. Whether infected or not. The most important thing in wound healing is the edge of the wound. The edge of the infected wound must not grow well. Therefore, the wound must not be infected. Clean it up in time after minor injuries, cover it properly, and take local or even systemic drugs in time when infection is found. In addition, why do deep wounds need tetanus? Because such an environment may allow aerobic bacteria to breed, the most common thing is that nails rust, which will kill people seriously; Open wounds are generally not a big problem. 4, the wound is tense! Very important and easy to ignore. Tight skin opens with a poke. You can't let the skin on both sides of the wound touch each other like Romeo and Juliet. So try to reduce the tension, especially when the wound has just been produced and has not been sealed. I can also put a band-aid on a minor injury now, and the direction of force is perpendicular to the wound, just to reduce the tension. Of course, don't do it too tightly, which will hinder the blood flow.
