Wound scab thick reason has the following aspects: 1, is due to the wound is deeper and lead to, general wound scab is a natural protection phenomenon, scab this material is due to the wound inside the red blood cells and fibrous proteins in the surface layer of the condensation and formation, after the formation of it can make the wound and the outside world to isolate, can effectively protect the wound, so that it is very good repair, growth, if the wound is deeper, it is inside the oozing of red blood cells and all kinds of exudate liquid, as well as fibrous protein content is more, the wound formed scab is also thicker, this is a normal phenomenon. If the wound is deeper, it exudes red blood cells and all kinds of exudate liquid, as well as fibrous protein content is more, the scab formed by the wound is also thicker, which is a normal phenomenon. 2, the reason why the wound scab is thick is caused by the wound appearing repeated infections, the wound appearing repeated infections, the amount of its exudate liquid increases, containing a large number of red blood cells as well as fibrous protein, in the process of such repeated infections, there is a large amount of liquid exudates repeatedly form scabs, which will lead to this phenomenon of thick scabs. In the process of repeated infection, a large amount of fluid exudes and forms scabs repeatedly, which can lead to the existence of thick scabs. At this time, we should take the necessary measures to clean the wound and change the medicine to reduce inflammation and sterilization, which is conducive to the healing of the wound as soon as possible.
