In that case, when disrupted the normal blood circulation and innervation of organs or tissues, gangrene may develop in them - the symptoms of this disease are made up of several fairly complex symptom, to assess the role and value of each of which should only be a qualified technician.
Symptoms of the disease
important to remember that the symptoms of gangrene may affect a very small part of the body and the whole body.The first signs of gangrene occur quickly after the blood flow is disturbed and the oxygen to the tissues - proved that the farther the affected tissue or organ located from the heart, the easier they develop this type of disease.
That is why any kind of tissue necrosis often affect limbs and gangrene of the feet becomes a complication, which is so often difficult for uncompensated diabetes and other complications of the peripheral blood circulation in the tissues.If a patient develops gangrene - signs of the disease manifest themselves, first of all, a change in color and normal
why the disease occurs?
important to remember that in every case where there is gangrene - the causes of this condition are a change in the normal blood supply or innervation and blood supply of tissues.The reasons may become:
impact of external factors:
- mechanical injury;
- chemical injury;
- effects of temperature (too high or too low);
- radiation injury.
- impact of internal factors:
- arterial thrombosis;
- occurrence of sclerotic or inflammatory changes in the intima of vessels.
And under the influence of external factors and internal factors influence a hotbed of impaired blood circulation may get an infection, which inevitably leads to the development of putrid septic meltdown fabrics.If the infection is in the development of the disease is not involved, gangrene remains aseptic.A special case is a gas gangrene wound infection, the main conditions of which are poor circulation and nerve supply to peripheral tissues while contact through damaged skin or mucous membranes of specific micro-organisms develop without the access of air (anaerobic microorganisms).
In diabetes the excess amount of glucose in the blood serum, which can not be absorbed into the body, has a damaging effect on the blood vessels that causes the development of atherosclerotic lesions in blood vessels and nerve fibers are damaged at the same time.
If the disease develops gangrene in diabetes - symptoms of the disease can occur at any level of blood glucose and carbohydrate metabolism disorders ago (which is why treatment is required any increase in glucose level).The first symptoms of gangrene may be to:
- appearance of tingling in the lower extremities, especially in the peripheral parts of them;
- occurrence of edema in the absence of heart disease, and kidney;
- change the structure of the foot - shaped stop "diabetic";
- cold snap of the peripheral part of the foot - the foot and lower leg;
- change the color of the skin in certain areas of the feet - there is local reddening or whitening of the skin;
- structural changes in the nails - there is a thickening of the nail plate, changing their color, revealed signs of a fungal infection, which responds poorly to therapy.
As in all other cases, diabetes may develop the symptoms of dry and wet gangrene.Dry, with diabetes mellitus often develops in the first type of the disease in patients with violations of water-electrolyte metabolism and depletion.This necrosis develops slowly enough and time to be mummified tissue, wrinkle and blacken.
first ghost dry gangrene becomes simultaneous occurrence of pain, change in skin color, cold limbs, while numbness and loss of sensation develops some time after that.Circulation stops almost completely, so the products of decay of tissues in the body come in limited quantities, and general condition of patients varies slightly.
Wet gangrene in diabetes usually develops in the second type of the disease in overweight patients - blood circulation is disrupted, and does not stop completely, so active decay products enter the body, causing the appearance of signs of severe intoxication.If you have any symptoms of the disease occur gradually - appears pale limbs and congestive hyperemia e veins, formed bubbles after opening which tissue masses begin to disintegrate with the emergence of a sharp and unpleasant smell.The patient appears severe pain and signs of intoxication, require immediate and active treatment.
If a patient with impaired blood circulation in the nidus of infection get special anaerobic microorganisms, developing gas gangrene - the causes of the disease are not only in blood disorders, but also the impact on the tissue specific microbes, the main condition for the existence of which becomes the absence of atmospheric accessoxygen.It is for this type of bowel gangrene may develop (its contents is always a anaerobes, the development of which is constrained by the normal local immunity of healthy tissue) or gangrene of the gallbladder caused by ingestion into the body of microorganisms from the intestinal lumen.In addition, the modes of transmission of gas gangrene in lesions of peripheral tissues are in the penetration of infection through wounds of the skin, in which terminate the access of oxygen - at a deep damage and contamination of the wound.
Disputes microorganisms begin to grow without oxygen, and when razvivaetsyagazovaya gangrene - symptoms develop very quickly after the injury.Toxins destroy muscle and connective tissue of an organism (there is a breakdown of proteins and carbohydrates, in particular process gas which accumulates in the tissues).
If gangrene develops anaerobic - symptoms of the disease is the appearance of pain and tissue conditions change, a color change occurs a little later.When pressed on the wound felt the swelling of tissues and the rustling sound, crepitations tissues.
