Why burn blisters?

For burn patients, if the damage is normal on the basis of second-degree burns or burns, and the dermis is damaged, after the damage to the dermis, it will cause the expansion of capillaries, resulting in increased exudate, so burn patients will show symptoms of blisters. If the blisters do not affect physiological activities, it is best not to burst them, because the fluid in the blisters will gradually be absorbed by the tissue. However, for larger blisters or blisters that are easily broken at the joints, try to keep the blister skin intact. In this case, it is necessary to use disinfection, debridement and sterile syringe to withdraw the liquid from the blister. After withdrawing the liquid from the blister, disinfection and bandaging are carried out. The blister skin can act as a biological dressing to protect the wound of the burn victim, and can reduce the pain threshold and facilitate the healing of the wound.
