Background: Necrotizing fasciitis is a rare but severe condition associated with high mortality. We encountered a patient with severe and rapidly progressing necrotizing fasciitis.
Patient: A 40-year-old male was hit by a tractor and received a wide laceration wound spanning the length of his posterior thigh. Soon after the accident, the wound was washed and debridement was performed. Two days postoperatively, we observed septic changes in the wound and diagnosed this condition as necrotizing fasciitis. Consequently, the patient's leg was amputated at the thigh. The patient, however, developed toxic shock syndrome after the amputation. Endotoxin adsorption using a polymyxin B-immobilized fiber column was performed for 2 days. Finally, a hip joint amputation was performed after 11 days, following which the patient's general condition gradually improved.
Discussion: Treatment for necrotizing fasciitis should be initiated promptly. Early debridement is associated with a significant decrease in mortality. In severe conditions, endotoxin and cytokine removal by blood purification is one of the most effective treatments. Although group A streptococci are widely known as "flesh-eating bacteria," we should also consider a wide variety of pathogenic organisms to be the probable cause of severe necrotizing fasciitis.
Conclusion: Management of necrotizing fasciitis requires careful investigation as well as an aggressive therapeutic approach, which may include urgent surgical intervention. In addition to surgery, endotoxin adsorption therapy should be considered.
