[Comprehensive treatment of 25 cases of acute necrotizing fasciitis].

From May 2013 to March 2020, 25 patients with acute necrotizing fasciitis were admitted to Beijing Chaoyang Emergency Rescue Center, including 18 males and 7 females, aged 7 to 78 years. The lesions were mainly located in the lower extremities, with the original lesion areas ranging from 20 cm×15 cm to 83 cm×42 cm. After admission, comprehensive systemic treatment was performed, the lesion area was cut open and drained as soon as possible, and the necrotic tissue was removed. Vacuum sealing drainage was performed when the necrotic tissue in the wound was reduced. The wounds were directly sutured or repaired with thin split-thickness skin grafts taken from head and/or thigh or local skin flaps after the wounds were improved. The skin grafts and flaps survived well after surgery, and the wound was completely closed. None of the 25 patients had amputation. A total of 21 patients were followed up for more than half a year, showing no recurrence of acute necrotizing fasciitis and no difference in the function of their injured limb after the wound healing than before the onset.
