Wet gangrene is a severe form of tissue death caused by bacterial infection, often due to underlying conditions like soft tissue damage and impaired circulation. Treatment involves surgery and antibiotics, and early diagnosis is crucial for a good prognosis. Prevention includes proper wound care and seeking medical attention at the first sign of infection. In severe cases, reconstructive surgery or amputation may be necessary.
Wet gangrene is an invasive form of tissue death that can occur with a bacterial infection. Individuals who develop wet gangrene generally have an underlying condition, such as soft tissue damage, with impaired circulation that initiates the onset of necrosis or tissue death. In order to prevent the gangrene from spreading to surrounding tissue, treatment generally requires surgery and the aggressive administration of antibiotic drugs. Prompt and appropriate treatment is the key to a good prognosis for this potentially life-threatening condition.
When soft tissue is adversely affected by trauma or disease, blood circulation can be impaired. Inadequate blood circulation can cause oxygen and nutrient deprivation which compromises the health of the affected area. Wet gangrene develops when the blood supply is completely cut off. Blood-starved tissues and, in some cases, organs become vulnerable to infections that can easily lead to tissue death in the absence of antibody protection.
A variety of laboratory and diagnostic tests can be used to confirm a diagnosis of wet gangrene. After an initial physical exam, a blood draw may be taken to help determine the extent of the infection. Typically, a tissue culture will also be done to determine the type of bacteria causing the infection. A series of imaging tests, including a magnetic resonance imaging (MRI), may be administered to determine how invasive the infection has become and whether it has affected one’s organs.
Early signs of wet gangrene infection can include skin discoloration and intense discomfort or pain in the affected area. Affected tissue often takes on a shiny, blistered appearance that gives this form of gangrene its name. It is not uncommon for blistering or skin ulceration to produce an offensive odorous discharge that may be opaque in consistency. Depending on the extent of the bacterial infection and the invasiveness of the necrosis, some individuals may experience soft tissue swelling which may be accompanied by malaise and fever.
Simple measures, such as proper wound care, can go a long way in preventing wet gangrene. Those who heal slowly, such as diabetics, are encouraged to pay extra attention to any wounds they may sustain, to keep wounds clean and dry, and to seek medical attention at the first sign of infection. If wet gangrene becomes extensively invasive or enters the bloodstream, septic shock can develop and cause additional symptoms, including a drop in blood pressure and impaired breathing. Death can occur if treatment for this aggressive form of gangrene is delayed or absent.
To reduce the risk of spreading wet gangrene, surgery is usually done to remove the affected tissue. Severe cases may require additional reconstructive surgery or amputation. Aggressive antibiotic therapy can be given orally, intravenously, or both. Those whose infection has impaired their body’s ability to function independently may be given artificial support to stabilize their condition, including supplemental oxygen to ease breathing when breathing is impaired.
