Necrosis is nothing but death, tissues,cells, organs of a living organism. The reasons are different. These include direct destruction by a traumatic agent or a trophic disorder. Perhaps, it is worth mentioning the problems with blood circulation. Factors that can lead to necrosis:
- chemical;
- mechanical;
- Electrical;
- thermal and others.
Necrosis of tissues or organs occurs whenThe impact of a mechanical force that exceeds the resistance of shells. The result is their breakdown. Necrosis of the tissues can occur as a result of long-term or short-term thermal effects. It's about burns and frostbite. It can also happen in those places where an electric current entered the body.
Necrosis of tissues and organs can be causedchemical substances. Dry necrosis can cause strong acids, colliquating - strong alkali. In both cases it is a question of chemical burns. Microbial toxins can also cause necrosis.
Necrosis of tissues or organs can be caused by circulatory problems. In this case, it will be conditioned by the following:
- wounding the vessel;
- the chemistry of the blood is broken;
- heart problems;
- obliteration of blood vessels.
Such necrosis often determines the course of any disease. For example, tissue necrosis plays a very important role in gangrene.
If tissue trophism is disturbed, necrosis can occur even with minimal impact on the affected area. An example is bedsores that occur when the spinal cord is damaged.
Necrosis of the intestine or any other organ is always much more dangerous than necrosis of the skin. Eliminating it is hard. It also can not always be found on time. It can be the cause of death.
There are certain conditions under which necrosis develops faster than usual. Its progression is affected by:
- microflora in the source of the disease;
- anatomical and physical features;
- phenomena of the external environment.
Anatomico-physical characteristics can be divided intogeneral, and also local. On the general state of the body, both acute and chronic infection can be detrimental. To the reasons it is possible to carry also an intoxication, an exhaustion, an avitaminosis and other similar. All this contributes to the development of necrosis.
Microbes and toxins also speed up tissue necrosis.It is unacceptable to get them into the zone with disturbed blood circulation. Subcooling increases the spasms of blood vessels, thereby increasing the problems with blood circulation. Overheating causes metabolic disorders.
Radiation can cause a strong and rapidnecrosis of tissues. This action has a very complex mechanism. It is based on the disorders arising from radiation sickness, as well as local effects on tissues.
Necrosis: treatment
Treatment of necrosis is local and common. Dry and wet necrosis is treated differently.
Local treatment of dry necrosis occurs in two stages. The first is the treatment of tissues, the second - the removal of dead tissue.
General treatment in this case includestreatment of the disease, which is the main one. Most medical measures in this case are aimed at restoring or improving blood circulation. With infectious diseases, they are fighting with antibacterial therapy.
With wet necrosis, the infection develops much faster. This means that treatment should be radical. If there is an opportunity to transfer it to dry necrosis - doctors use it.
Wet necrosis is difficult to eliminate.In some cases, its distribution can be stopped only by amputation. Doctors do everything possible to prevent this, but the stakes are too high, and the delay can cause more trouble.
