When we are injured, we often use gauze bandages to bandage, fearing that blood will seep out. In addition, medical gauze bandages are very hygienic. After wrapping the wound, they can also isolate external injuries and bacterial infections. However, when using medical gauze bandages, if they are tied too tightly, congestion will occur at the wound. So how to use gauze bandages to prevent congestion? Let me introduce it to you below.
Gauze bandages have three functions to prevent scars. First, they can cause local tissue hypoxia at the wound suture site, causing fibroblasts, collagen fibers, and matrix to lose oxygen nourishment, and scar hyperplasia is prevented. Second, the pressure of medical gauze bandages can reduce 2-macroglobulin in local serum that prevents collagenase, which is conducive to the decomposition of collagen. Third, after the local tissue is compressed, the deposition and synthesis of mucopolysaccharides can be reduced, and collagen synthesis can be reduced. It has no effect on mature scars that are more than one year old.
The above is the method of using gauze bandages to prevent congestion introduced to you. I hope it will be helpful to you!
