Necrotizing fasciitis

  1. 1. SEGi College SarawakFACULTY OF NURSING & ALLIED HEALTH Foundation in Science Necrotizing Fasciitis By Darrell Nadeng Dominic
  2. 2. • Necrotizing Fasciitis is commonly known as “Flesh-eating disease” or “Flesh-eating bacteria syndrome”, is a RARE infection of the deeper layers of the skin and subcutaneous tissues. It can destroy muscles, skin and underlying tissue.• “Necrotizing” refers to something that causes body tissue to die.
  3. 3. What causes Necrotizing Fasciitis?
  4. 4. Necrotizing Fasciitis is commonly caused by Group A Streptococcus (GAS) bacteria, which is the same type of bacteria that causes strep throat. However, severaltypes of bacteria, such as staphylococcus have also be associated with this disease.
  5. 5. An individual with Strep Throat
  6. 6. How do you obtainNecrotizing Fasciitis??
  7. 7. • The bacteria that causes Necrotizing Fasciitis can enter the body following surgery or injury. They can also enter the body through : - Minor cuts - Insect Bites - Abrasions• In some cases, it is unknown how the infection began. Once the infection takes place, it rapidly destroys muscles, skin and fat tissue.
  8. 8. The Symptoms
  9. 9. • Increasing pain in the general area of a minor cut, abrasion, or other skin opening.• Pain that is worse than would be expected from the appearance of the cut or abrasion.• Redness and warmth around the wound, through symptoms can begin at other areas of the body.• Flu-like symptoms such as diarrhea, nausea, fever, dizziness, weakness, an d general malaise.• Intense thirst due to dehydration
  10. 10. More advance symptoms occur around thepainful infection site within three or four days of infection. They include :• Swelling, possibly accompanied by a purplish rash.• Large, violet-colored marks that transform into blisters filled with dark, foul-smelling liquid.• Discoloration, peeling, and flakiness as tissue death (gangrene) occurs.
  11. 11. Critical symptoms, which often occur within four to five days of infection, include :• Severe drop in blood pressure• Toxic shock• Unconsciousness
  12. 12. Caucasian with necrotizing fasciitis. The leftleg shows extensive redness and necrosis.
  13. 13. Diagnosis of Necrotizing Fasciitis
  14. 14. • Diagnosis is often based on advance symptoms, such as the presence of gas bubbles under the skin. Laboratory analysis of fluid and tissue samples is done to identify the particular bacteria that are causing the infection. Treatment however, begins before the bacteria are identified.• Household members and others who have had close contact with someone with necrotizing fasciitis should be evaluated if they develop symptoms of an infection.
  15. 15. Free air in the soft tissues due to necrotizing fasciitis
  16. 16. Necrotizing fasciitis causing air in soft tissues
  17. 17. Micrograph of necrotizing fasciitis, showing necrosis (center of image) of the dense connectivetissue, i.e. fascia, interposed between fat lobules (top-right and bottom-left of image).
  18. 18. Treatments for Necrotizing Fasciitis
  19. 19. Immediate treatment is needed to prevent death• Powerful, broad-spectrum antibiotics given immediately through a vein (IV)• Surgery to drain the sore and remove dead tissue• Special medicines called donor immunoglobulins (antibodies) to help fight the infection in some cases
  20. 20. Other treatments may include :• Skin grafts after the infection goes away to help your skin heal and look better• Amputation if the disease spreads through an arm or leg• 100% oxygen at high pressure (hyperbaric oxygen therapy) for certain types of bacterial infections
  21. 21. Necrotic tissue from the left leg is beingsurgically debrided in a patient with necrotizingfasciitis
  22. 22. The left lower limb after extensive debridement
  23. 23. Prevention
  24. 24. • Keep all wounds clean and watch closely for any signs of infection. Early detection and treatment of infection may be the best measure to prevent the subsequent development of necrotizing fasciitis. Promptly seek medical care if any signs or symptoms of infection appear.
  25. 25. • Maintaining good personal hygiene and frequent hand washing can prevent infection and help control the spread of infection. Following guidelines of proper sterile surgical technique and practicing strict barrier (gloves, gowns, masks, etc.) and isolation precautions in hospitals can also allow health care personal prevent the development and spread of infection.
  26. 26. Aimee Copeland - aged 24 Survivor of Necrotizing Fasciitis
  27. 27. A 23 year-old woman developed a left facial cellulitis which progressedrelentlessly with necrosis. Debridement was performed on several occasionsto halt the spread of the necrosis. The ophthalmic team was consulted 10 daysafter her admission because of left ptosis. Examination revealed poor ocularmovement, an urgent CT scan revealed cavernous sinus thrombosis. She wasgiven anti-thrombotic treatment by the medical team. The facial defect waslater reconstructed with myocutaneous graft from the thigh by the plastic team.
