What Is Gangrene? Preventing It? (Health And Medical Video June 2018).

Death of tissues of a living organism is a threatening condition in which operative intervention can not be delayed.

Gangrene called the death of tissues of a living organism. Often, gangrene is prone to tissue that directly contacts or interacts with the external environment through certain anatomical channels (eg, lungs).

Causes and mechanisms of development

The main reason for the development of the gangrene is a circulatory disorder in any part of the body due to clogging of the vessel by thrombus or embolus, excessive narrowing of the vessels, systemic diseases and other causes.

As a result of circulatory disorders, tissues begin to necrotizing: blood proteins coagulate, its uniform elements break down.

In the absence of nutrition, the tissues dry up and wrinkle, the products of decay of blood cells immitate tissues, which makes the latter acquire a dark (and even black) color. Distinguish dry and moist gangrene.

Dry gangrene

Dry gangrene is more often formed with a slow cessation of blood circulation, which allows the body to create an effective barrier that protects it from harmful toxins, decomposing tissues.

The onset of this disease is characterized by severe pain in the affected area (below the site of blockage of the vessel). The skin becomes marble color, it becomes cold to the touch, the pulse wave is no longer felt.

Over time, a person loses all kinds of sensitivity in the affected area (the longest holds on pain sensation), violated functions of the affected organ. If the limb afflicts, then its immortality begins with the most distant parts and gradually rises above to the level of circulation.

In most cases, at this level, a clear boundary is created that separates the dead tissue from the living. The general condition of a person, as a rule, is rather good, the symptoms of intoxication are not expressed. Subsequently, an independent rejection of the affected area may occur.

Wet gangrene

Moist gangrene is much more dangerous than dry. It develops rapidly due to a sudden stroke of the blood stream, resulting in the body does not have time to do any protective measures. In the tissues, the infection begins to develop: the affected organ increases in volume, there is an unpleasant smell with a sweet rotten tinge.

The general condition of a person with a moist gangrene is very heavy: in the blood of a lot of toxins that affect all internal organs, which quickly leads to the development of sepsis and infectious and toxic shock.

Prophylaxis of gangrene

The best prevention of the development of deadening of tissues is the early diagnosis and timely elimination of diseases that lead to disorders of the blood circulation: injuries, diseases of the heart and blood vessels, frostbites, etc.


The main and only remedy for gangrene is surgical intervention with the removal of the affected part of the body.

At the same time, in dry gangrene it is possible to operate with some delay, waiting for education limits the shaft (at the same time necessarily specialized surveillance, which prevents the possibility of degeneration of dry gangrene in moisture).

When wet gangrene you need to operate immediately - this is the only thing that can save a person's life.
