Introduction

Seek immediate medical attention if you notice the following signs:

• A part of your body turns blue or black.
• A wound doesn't heal within seven to fourteen days.
• You experience severe localized pain.
• You have persistent, unexplained fever.
• Pus or blood drains from the wound.
• You notice a foul-smelling odor from the wound.

Follow-up

• Keep the affected area clean.
• Follow the healthcare provider's instructions for changing bandages and dressings.
• Make sure to complete the prescribed antibiotic course.
• Limit activity as much as possible for a few days.

Prevention

The most effective defense against gangrene is prevention.

• Keep wounds clean and sterile by thoroughly cleaning with antiseptic solution.
• Be vigilant for signs of infection like pus, redness, swelling, or unusual pain.
• Consult a healthcare provider if any wound becomes infected.
• Individuals with diabetes should manage their blood-sugar levels with proper medication.
• Educate yourself about proper foot care, especially if you have diabetes. Regularly inspect your feet for any signs of injury or changes in skin color. Immediately tend to any small injuries. Keep your nails trimmed and wear comfortable, well-fitting shoes.

Outlook

A person's prognosis with gangrene depends on several factors:

• Which part of the body is affected.
• The extent of the gangrene.
• The cause of the gangrene.
• The overall health status of the individual.

Generally, the prognosis is favorable, except in cases where the infection has spread through the bloodstream. Early-stage gangrene is typically treatable with intravenous antibiotics and debridement. Without treatment, gangrene may lead to a fatal infection.

Gas gangrene can progress rapidly, with a 20-25% death rate if it spreads to the bloodstream. However, when diagnosed and treated early, about 80% of people with gas gangrene survive without needing amputation, and only 15-20% require some form of amputation.

People with dry gangrene often have other health issues that complicate recovery, and other system failures usually prove fatal.
