Study Notes
- Renaldo Womatalze specializes in diagnosing gangrene based on symptoms and supports it with tests like imaging.
- Types of gangrene:
- Dry gangrene: end result of chronic ischemia without infection, not salvageable once developed, not as emergent as gas or wet gangrene, can develop into wet gangrene if infection occurs.
- Wet gangrene: characterized by thriving bacteria, poor prognosis due to sepsis, usually develops rapidly due to venous or arterial blood flow blockage, affected part saturated with stagnant blood, rapid growth of bacteria, toxic products absorbed and cause sepsis, high mortality, emergency amputation often required.
- Gas gangrene: bacterial infection that produces gas within tissues, caused by Clostridium or non-clostridial species, infection spreads rapidly as gases expand and infiltrate healthy tissue.
- Necrotizing fasciitis (hemolytic streptococcal gangrene): infects deep into the body along tissue planes, spreads rapidly, high mortality rate.
- Noma: a gangrene of the face.
- Fournier gangrene: type of necrotizing fasciitis that usually affects the genitals and groin.
- Severe mesenteric ischemia: may result in gangrene of the small intestine due to severe ischemic colitis that may result in the large intestine gangrene.
- Dry gangrene: not accompanied by infection, not as emergent, can develop into wet gangrene, over time may become wet gangrene if infection occurs.
- Wet gangrene: characterized by thriving bacteria, poor prognosis due to sepsis, affected part saturated with stagnant blood, rapid growth of bacteria, toxic products absorbed and cause sepsis, high mortality, emergency amputation often required.
- Gas gangrene: bacterial infection that produces gas within tissues, infection spreads rapidly as gases expand and infiltrate healthy tissue.
