The skin has been running after the scald is due to the exudation of the body’s tissue fluid. Second-degree scalded epidermal injury, the dermis of the skin cells are exposed, the capillaries around the cells produce aseptic inflammation, capillary permeability increases, resulting in extravasation of intracellular fluid and tissue fluid in the capillaries, resulting in the formation of exudate, which is a normal pathophysiological reaction that occurs after scalded. This is a normal pathophysiological reaction after the scalded skin. At this time, bacteria can easily invade the scalded skin and cause infection, so we should pay attention to keep the wound clean and dry, and apply burn ointment appropriately to promote recovery and prevent infection until the wound is healed. If the exudate formed relatively large blisters, you can use a sterile needle to puncture, and the blisters of the blisters swabbed dry, iodine-vapor oil gauze cover, bandage, and change the medicine regularly. Scalded should be promptly to the regular hospital, follow the doctor’s instructions for disposal.
