fact that gangrene of the feet is the most likely option of developing this life-threatening complication of many diseases, no one doubts.
gangrene this location due to the fact that these parts of the body supplying the worst of all - to the extremities are only one or two main arteries, so the possibility of the development of collateral blood flow is restricted.Thrombosis, embolism, and combinations of these conditions may develop in the large arterial trunks almost simultaneously, so the possibility of a full-fledged recovery of spontaneous circulation is minimal, and necrotic process (gangrene of the extremities) is progression opportunities, but the rate of occurrence of blood disorders explains the probability of dry and wet gangrene.
As developing gangrene
starting moment for the beginning of the pathological process in the peripheral tissues of the limb is becoming a significant limitation or complete cessation of adequate inflow of arterial blood and oxygen supply.That is why the ans
- stage reversible disturbances of blood flow, which is in liquidation tissue condition can be restored;
- stage of irreversible changes, which even after the adequate and complete restoration of blood flow not only reduce the symptoms of the disease, but will also burden the patient's condition through active into the blood tissue decay products and toxins.
If gangrene feet - the initial stage of the disease is manifested by pain, while the color change and nervous disorders appear somewhat later, and their severity will depend on the type of circulatory disorders.When dry gangrene color damaged tissues very quickly turns black, and in them there is dehydration - prognostically more favorable for the patient such a scenario, because the body itself forms the line of demarcation between viable and healthy tissues, and entry into the systemic circulation of toxins is minimal.
wet gangrene or toes of the foot occurs when blood flow is restricted, but not completely cease, and by maintaining the residual blood flow occurs in the systemic circulation decay products.With the development of wet gangrene often difficult and venous outflow, due to which there is swelling of affected tissues and they become livid appearance, and open wounds are beginning to publish an unpleasant smell.
Signs and symptoms
Asked by - looks like gangrene, doctors point out that the affected tissues differ from healthy visually (color change, increasing or decreasing their volume), appear nervous disorders, but the first signthe disease becomes.Pain when gangrene is so strong and painful that the patient is torn, trying to find relief of their condition, but it does not happen - the intensity of the pain only increases the pain will continue until the complete immobilization of nerve fibers in the affected part of the lower limb.
color change of the affected area is characteristic of any type of gangrene - poor circulation in the primary whitening occurs, caused by insufficient inflow of arterial blood.Then, depending on the situation, there is a clear distinction between healthy and damaged tissue (mummification affected tissue) and formed the classic dry gangrene of the feet, where the development of the tissue blacken and decrease in the amount of, or the penetration of infection, there is a bacterial inflammation and formed wet gangrene.
In this case, the condition of inadequate blood flow lesion limbs and all his tissues become ideal breeding ground for microorganisms, and into the systemic circulation receives a large amount of toxins (bacterial and tissue), which explains the rapid development of the common symptoms of the disease.In the case where there is a moist gangrene of the feet, the pathologic process is able to spread to areas of the limb, located above the original site of circulatory disorders.
If any version of the feet gangrene should be remembered that the cause of the pathological process are circulatory disorders, so any local treatment, including ointment from gangrene, is only the auxiliary component.Its purpose becomes limiting growth of microorganisms in the affected segment of the limb, but the effectiveness of such therapy is only when with gangrene treatment is directed to the restoration of arterial blood flow, reducing intoxication, systemic suppression of infection in the wound.
for dressings with gangrene can use any ointments containing antiseptic (preventing the penetration of infection) funds, while antibiotic ointment no therapeutic effect do not have, because they do not affect the cause of the pathological process.In addition, it is important to adequate analgesia, because severe pain becomes an additional stress factor that impairs blood flow in tissues, a systemic detoxification therapy, maintaining basic vital functions and the status of its organs and systems.
