Gangrene Causes, Symptoms and Treatment

Oct 27, 2011 > Various
Gangrene is a term that refers to the death of body tissue due to diminishment or loss of blood supply, leading to nutrient and oxygen deprivation. There are three major types of gangrene: moist, dry, and gas gangrene. Although gangrene usually affects extremities, it can sometimes affect the internal organs.

Gangrene Causes

Moist gangrene is generally caused by a sudden stoppage of blood floe to a body site, usually resulting from burning by heat or by acid, from severe freezing, from a physical accident that destroys the tissues, from keeping a tourniquet in place too long, or from a blood clot or other blockage. The tissue death that results form loss of blood supply is accompanied by decomposition due to bacterial action. The gangrenous rapidly as toxins (poisons) are formed in the affected tissues and absorbed.

Dry gangrene usually occurs gradually and results from a slow, progressive reduction of blood flow in the arteries. There is generally no bacterial decomposition; the tissues simply become dry and shriveled. This type of gangrene occurs only in the extremities. It may occur as a secondary effect of arteriosclerosis in the elderly, of advanced stages of diabetes, or of Buergerís disease (an inflammatory condition tha affects the blood vessels of the limbs, primarily the legs).

Gas gangrene is often caused by infection of a wound by anaerobic (able to live without air) bacteria, which are commonly found in soil. It can follow rapidly after contamination of deep wounds. The bacteria break down tissues, giving off gas and toxic by-products.

Gangrene in an internal organ can be caused by any condition that cut off blood supply to an area. For example, if a loop of intestine is caught in an opening in the abdominal wall, the blood supply to that part of the intestine may be cut off (causing what is called a strangulated hernia), and gangrene may the occur in that section of the tissue. In acute appendicitis, areas of gangrene may occur in the walls of the appendix, with rupture of the appendix through the gangrenous area. In severe cholecystitis (inflammation of the gallbladder, usually associated with gallstones), gangrene can develop in areas where the stones compress the mucous membrane, cutting off the blood supply.

Gangrene Symptoms

Gangrene Causes, Symptoms and Treatment Moist gangrene is characterized by a purplish-red, bruised appearance; by swelling; and, often, by blisters.

Dry gangrene is marked by gradual shrinking of the tissues, which first grow cold and lack a pulse, then turn brown, then black. Usually there is a sharp line of demarcation where the gangrene stops because the unaffected tissue nearby is continuing to receive blood. This type of gangrene is sometimes called mummification of tissue because of the dry, shriveled, and dark appearance.

The initial symptoms of gas gangrene are swelling, paleness of skin, and thin, bloody (but not foul) discharge. The characteristic foul smell comes later in progression of this form of the disorder. It is an acute, painful condition in which the muscles and tissues under the skin become filled with gas and a thin, brownish-black fluid.

Symptoms of gangrene in an internal organ may include pain, tenderness over the organ, and fever.

Gangrene Diagnosis

The appearance of the affected area usually suggests the diagnosis to the physician. Laboratory analysis of a tissue specimen will allow the identification of the ineffective microorganism, which is necessary for selection of an appropriate antibiotic. Areas of gas gangrene may be seen on X-ray.

Gangrene Treatment

Treatment of gangrene generally involves cleaning of the area and administration of antibiotics. The effectiveness of antibiotic therapy seems to depend on the time elapsed between injury or infection and the beginning of treatment.

In the case of gangrene caused by deterioration in the blood supply of the elderly or gangrene associated with appendicitis, hernia, diabetes, or Buergerís disease, the treatment begins with the diagnosis and treatment of the underlying condition.

Gangrene Prevention Preventing gangrene in an open wound begins with cleanliness. All dirt and particles in an open wound should be removed as soon as possible, and the wound should be cleansed with a soap solution and water. Burned skin requires careful, antiseptic handling to avoid infection. Frostbite also is dangerous because freezing impairs the circulation of the skin, making it tender and easily damaged. Frostbitten skin, especially on the fingers, toes, and earlobes, must be handled with great care.

Gangrene Causes, Symptoms and Treatment #0Pulmonary Embolism Symptoms and Prevention
Pulmonary embolism is a condition in which a part of blood clot in a vein breaks away and travels through the heart and into the pulmonary circulatory system. Here the vessels leading from the heart branch like a tree, gradually becoming smaller until finally they form capillaries, the smallest blood vessels. Depending on its size, the clot will at some point reach a vessel through which it cannot pass, and there will lodge itself. The clot disrupts the blood supply to the area supplied by that vessel. The larger the clot, the greater is the area of lung that loses its blood supply, and the more drastic the results to the patient.

Are you looking how much Lasik Eye Surgery Cost? There have always been concerns about LASIK because of its tendency to induce higher-order aberrations. The advancement of the LASIK technology has helped reduce the risk of clinically significant visual impairment after surgery. There is a correlation between pupil size and aberrations. Effectively, the larger the pupil size, the greater the risk of aberrations. This correlation is the result of the irregularity between the untouched part of the cornea and the reshaped part. Daytime post-lasik vision is optimal, since the pupil is smaller than the LASIK flap. But at night, the pupil may expand such that light passes through the edge of the LASIK flap into the pupil which gives rise to many aberrations, including the appearance of halos surrounding sources of light. There are other currently unknown factors in addition to pupil size that also may lead to higher order aberrations

Are you looking for angelman syndrome causes risk factors? here is some good stuff about angelman syndrome causes risk factors. Angelman syndrome is a complex genetic disorder that primarily affects the nervous system. Characteristic features of this condition include developmental delay, intellectual disability, severe speech impairment, and problems with movement and balance (ataxia). Most affected children also have recurrent seizures (epilepsy) and a small head size (microcephaly). Delayed development becomes noticeable by the age of 6 to 12 months, and other common signs and symptoms usually appear in early childhood.

Chlamydia is a bacterial infection disease transmitted when people have sexual relations. It is the most common sexually transmitted disease (STD) in the United States, with over 2.8 million affected individuals each year. Among adults, about 5% of the population is estimated to be infected. Among sexually active adolescent females, about 10% are infected.
Gangrene Causes, Symptoms and Treatment #6Leukemia Symptoms and Therapy
Leukemia is cancer of blood-forming tissue, including the lymph system and bone marrow. Because leukemia involves blood cells circulation through the body rather than a fixed mass of tissue, leukemia is sometimes not considered a true cancer. However, leukemia cells, when studied under a microscope and in cell cultures, behave like cancer cells found in tumors. There are at least ten different kinds of blood cells that have been identified with various forms of the disease, which is why if frequently is referred to as leukemia. In addition, there are both acute and chronic forms of leukemia, such as acute granulocytic leukemia and chronic lymphatic leukemia, named after the particular kind of white blood cells that are most affected.

Are you looking for colorectal cancer symptoms in women? Here is some article about colorectal cancer symptoms in women. The colon is the part of the digestive system where the waste material is stored. The rectum is the end of the colon adjacent to the anus. Together, they form a long, muscular tube called the large intestine (also known as the large bowel). Tumors of the colon and rectum are growths arising from the inner wall of the large intestine. Benign tumors of the large intestine are called polyps. Malignant tumors of the large intestine are called cancers.
Gangrene Causes, Symptoms and Treatment #8Coronary Artery Disease Treatment Guidelines
It can be difficult to determine whether chest pain is caused by angina. Whenever a person develops symptoms that could be angina, a complete medical evaluation is needed to determine whether coronary artery disease is present and, if so, how severe it is (see also chapter 7). The individual's medical history and descriptions of the pain, actions that cause the pain, and actions that make it better may raise a doctor's suspicion of coronary artery disease, but these factors are not sufficient for actual diagnosis. Likewise, physical examination and blood tests may show that the patient is at risk, but cannot actually diagnose the condition. An electrocardiogram may or may not show changes of cardiac ischemia. An exercise electrocardiogram, a ''stress test'' done while a person is performing a specific amount of exercise, is more likely to demonstrate whether coronary disease is present. A particular change in the electrocardiogram during exercise can demonstrate that coronary artery disease is present. Even an exercise electrocardiogram is not 100 percent reliable in diagnosing coronary artery disease.
Gangrene Causes, Symptoms and Treatment #9Staying Fit during Pregnancy
Like many other attitudes, our thinking on fitness during pregnancy has changed in recent years. No longer is a pregnant woman treated as fragile. A woman needs to be quite careful when carrying a baby, but these days a doctor is more likely to advise against a sedentary lifestyle for a healthy pregnant woman. Exercise during pregnancy can increase a womanís muscle strength, making delivery of the baby easier and faster. Exercise can also help control her weight, making it easier to get back to normal weight after delivery. The baby may benefit from the motherís exercise program as well.

Are you looking for Cochlear Implant Cost? A cochlear implant (CI) is a surgically implanted electronic device that provides a sense of sound to a person who is profoundly deaf or severely hard of hearing. The cochlear implant is often referred to as a bionic ear. As of April 2009, approximately 188,000 people worldwide had received cochlear implants; in the United States, about 40,000 adults and over 30,000 children are recipients. The vast majority are in developed countries due to the high cost of the device, surgery and post-implantation therapy. A small but growing segment of recipients have bilateral implants (one implant in each cochlea).
Gangrene Causes, Symptoms and Treatment #12Hiatus Hernia Treatment
The term hiatus hernia describes diaphragmatic hernia or weakness in the diaphragm, the horizontal muscular wall separating the organs of the chest from the organs of the abdomen. A hernia is an abnormal protrusion of an organ or tissue through an opening. A hiatus, or opening, permits the esophagus to carry food from the mouth to the stomach. Blood vessels and nerves also pass through the diaphragm. The diaphragm is an important group of muscles for contracting and expanding the lungs, forcing air in and out of the lung tissues.
