What is second degree burn?

Answer 1

.

An injury to tissues caused by heat, chemicals, electricity, or irradiationeffects.

The commonest type of burn is that due to thermal injury, in which some portion of the body surface is exposed to either moistor dry heat of sufficient temperature to cause local and systemic reactions. Clinically, the extent of such a burn is often expressed as first degree, second degree, and so forth. Different systems of classification exist.

First-degree burns result in some redness and swellingof the injured part, without necrosisof any tissue or the formation of blisters. Healing is completed in a few days without scarring.

Second-degree burns show a variable destruction of parts of the epidermisso that blistering occurs. Healing by regenerationin such superficial burns does not necessitateskin grafting, unless secondary infections ensue; no scarring results.

Third-degree burns are marked by complete destruction of the epidermis of a region, including the necrosis of accessory skin structures like hair and sweat-gland. A brownish-black escharmarks the destroyed tissue. This is sloughoff and that defect becomes filled with granulationthat later consolidates and changes to form a dense, thick scar. Complications may occur without adequate care, and grafting is not unusual, sometimes being required because of contractureof the scar tissue.

In fourth-degree burns, tissue is destroyed to the level of or below the deep-fascialying beneath the subcutaneousfat and connective tissue of the body. Muscle, bone, deeper nerves, and even organs may be injured or destroyed by this severe degree of burn. Healing is usually a slow, involved process, requiring much reparative and reconstructive work by surgical specialists.

Electrical burns result from the amount of heat incident to the flow of a certain amount of electricity through the resistance offered by tissues. From a practical standpoint, most of the resistance offered to the passage of an electric current is that of the skin and the interface between the skin and the external conductor. Therefore, most electrothermalinjuries are limited to the skin and immediately subjacenttissues, although deep penetrationmay follow large voltages.

Most chemical burns result from the action of corrosiveagents which destroy tissues at the point of contact. Exposure of the skin, eyes, and gastrointestinal-tractare commonest.

Answer 2

A 2nd degree burns damage both layers of skin, the epidermis and dermis. Heat or very severe sunburns or chemical burns can cause 2nd degree burns. The skin is red and has blisters that may open and leak clear fluids, making the skin to appear wet. The burned skin may look patchy. These burns are usually painful, and the area often swells. The burn usually heals in 3 or 4 weeks. Scarring may occur.

Answer 3

I can be caused by any hot object. It is very commonly caused by severe sun burn when blisters form.

Answer 4

For a second degree burn, you will see redness. There will also be blisters forming.

Answer 5

Just about any kind of heat scource. But your skin has to be under the heat for a while to burn tho the 2nd or 3rd degree

Answer 6

You will see redness. There will also be blisters forming.

Answer 7

You have damage your nerve cells. A 3rd degree burn kills them so it is not painful.

Answer 8

It is because you have burned your nerve cells which cause pain. Third degree burns kill the cells so you feel no pain.

Answer 9

It is because you have burned your nerve cells which cause pain. Third degree burns kill the cells so you feel no pain.
