A necrotic wound is a wound that contains dead tissue. Wounds of this type are often discolored and softened with a very unpleasant odor. Necrosis in a wound can have a number of causes, including insect or animal venom. Treatment of a necrotic wound is extremely important, as necrosis can lead to fatal infection. Medical worms or surgery may be required to remove any dead tissue in a wound.
Healthy tissue that has died is often referred to as necrotic tissue. When part of the tissue in a wound dies, this is known as a necrotic wound. These types of injuries require immediate medical attention, as they are often very serious.
A necrotic wound will usually be very discolored. Often it will be black, but it can also be yellow, green, or white. It is also usually very soft and mushy, and will sometimes be covered with a crust or patches of crusts. However, one of the most unpleasant characteristics of necrotic tissue is its odour. This odor occurs when dead tissue begins to decompose or rot.
There can be several causes of a necrotic wound. Severe frostbite is one of the most common causes of necrotic tissue. When soft tissue freezes, the cells expand and often burst, causing the tissue to die. Necrosis can also occur when the supply of blood and oxygen is cut off from a certain part of the body. This can happen when a string is wrapped tightly around a finger, for example.
Certain types of venom can also cause necrosis. The venom of some vipers can cause a necrotic wound, for example. Brown recluse spider bites have also been known to cause necrotic wounds in victims.
Prompt treatment of a necrotic wound is very important, as these wounds can be fatal if left untreated. Bacteria will usually start to grow on the dead tissue. This bacteria will usually spread to other parts of the body, such as the heart or lungs.
Treatment for a necrotic wound usually involves removal of dead tissue, which is sometimes known as debridement. In some cases, multiple worms may be placed in the wound. While this practice may seem pretty unhealthy to many people, doctors have been doing it for quite some time. The worms remove dead tissue by eating it. Dead tissue can also be removed surgically, but this is usually more common when a necrotic wound is on a finger or limb.
