Blister burn

Introduction II ° burn: deep into the dermis, local blisters, it is also known as vesicular burns.

Cause

Cause: caused by high temperature such as hot water, steam, flame, electric current.

diagnosis:

1 Select II ° only hurt the shallow layer of the dermis, a part of the hair layer is healthy. Due to more oozing, the blisters are fuller, and the effusion is obvious after rupture; the base is swollen and red; there is severe pain and hyperesthesia; the skin temperature is increased. If there are no complications such as infection, it can be cured in about 2 weeks. No scars are left behind, and there may be pigmentation in the short term and good skin function.

2 deep II ° injured and deep dermis, skin attachment remains. Because the surface layer of the south is slightly thicker, the blisters are smaller or flatter, and the feeling is slightly dull, and the skin temperature can be slightly lower. After the epidermis, the wound surface is light red or red and white, or the reticular embolization of the blood vessels; the surface exudate is less, but the bottom swelling is obvious. If there are no complications such as infection, it can be cured in 3 to 4 weeks. Because there is some granulation tissue in the middle of the repair process, there is scar, but the skin function is basically preserved.

Differential diagnosis

Differential diagnosis:

1 ° burn: only injured the epidermis, local redness, it is also known as erythema burn. There is pain and burning, and the skin temperature is slightly higher. 3~5d can be cured and desiccated without leaving scars.

II ° burn: deep into the dermis, local blisters, it is also known as vesicular burns. The shallow II° only injured the shallow layer of the dermis, and some of the germinal layers were alive. Due to more oozing, the blisters are fuller, and the effusion of the wound surface is obvious after rupture. The base is swollen and red, with severe pain and hyperesthesia, and the skin temperature is increased. If there are no complications such as infection, about 2w can be cured, no scars will be left after the healing, and pigmentation can occur in a short period of time, and the skin function is good. Deep II° injured the deep layer of the dermis, leaving skin attachments. Because the degraded surface layer is slightly thicker, the blisters are smaller or flatter, and the feeling is slightly dull, and the skin temperature can be slightly lower. After the epidermis, the wound surface is light red or red and white, or the reticular embolization of the blood vessels, the surface exudate is less, but the bottom swelling is obvious. If there are no complications such as infection, 3~4w can be cured, and scars are left behind, but the skin function is basically preserved.

III° burns: It can damage the whole layer of the skin and can reach subcutaneous, muscle and bone. Skin necrosis, dehydration can form eschar, so it is also called eschar burn. The wound has no water, wax or white, or dendritic embolization of the blood vessels, like leather, even carbonized. The feeling disappeared and the skin temperature was low. Natural healing is very slow, it needs to be detached from eschar, and granulation grows and then forms scars. Not only does it lose skin function, but it is often deformed. I° is easy to identify, and shallow II°, deep II° and III° are not easy to judge immediately. Due to uneven heat, there may be transition zones between different depths, such as wound infection or concurrent shock, which can deepen the depth of injury.
