Risk Factors

Factors that may increase your chance of developing gangrene include:


Treatment of gangrene includes:
  • IV antibiotics—to treat infection
  • Debridement —surgical procedure to cut away dead and dying tissue, done to try to avoid gangrene from spreading
  • Supportive care, including fluids, nutrients, and pain medication to relieve discomfort
  • Blood thinners—given to prevent blood clots
  • Surgery may also be done to restore blood flow to the affected area
  • Amputation—removal of severely affected body part
  • Hyperbaric oxygen treatment—exposing the affected tissue to oxygen at high pressure may have some benefit
