You may be more likely to develop this condition if you:. Smoking, drinking alcohol, and using intravenous drugs may also add to your risk of developing gangrene. Sometimes the first sign of dry gangrene is a reddish line that develops around the affected tissue. This line may later turn black. In this case, you may not have any symptoms on your skin or limbs. However, you may have pain, an unexplained fever that lasts a long time, or low blood pressure.
You may also experience confusion. Your doctor may suspect that you have gangrene based on your medical history and symptoms. They may also use a combination of additional diagnostic methods to determine your condition. A scraping of tissue from your affected body part may be examined with a microscope to look for dead cells. Some kinds of imaging are helpful in diagnosing the spread of gangrene in your internal tissues.
An anarteriogram test may be performed if doctors suspect that your gangrene is related to a circulatory problem. This test uses X-rays to monitor the flow of a special dye through your arteries, showing whether any arteries are blocked. Your doctor may prescribe antibiotics if bacteria are present.
These are typically given intravenously, or through a needle directly into the bloodstream. For people with poor circulation that results in gangrene, vascular surgery surgery on the arteries or veins may be recommended in order to improve the flow of blood through the veins to body tissues. Placing a person with gas gangrene in a special oxygen-rich environment can slow the growth of bacteria. This allows the skin to begin healing. It also brings oxygen to the damaged tissue to promote healing.
In serious gangrene cases, the dead tissue or body part may need to be removed. This process is called debridement. Debridement can be done with surgical tools or with chemicals. Accident victims and persons with serious injuries may be also at risk for gangrene.
Treatment of gangrene includes removal of the dead body tissue through surgery. If the area of the gangrene involves a whole limb, amputation is usually indicated. Antibiotics should be given in cases of gangrene caused by bacterial infections. The most effective measure to prevent gangrene is to practice proper wound care in cases of injury to prevent infection by bacteria. Wounds should be inspected and cleaned regularly. For people who have chronic conditions such as diabetes or atherosclerosis, proper monitoring of the medical condition may decrease the risk of developing gangrene.
