Postoperative necrotizing fasciitis in children

Necrotizing fasciitis is a rapidly progressive soft tissue infection, involving the skin, subcutaneous tissue, and superficial fascia. It is a rare but life-threatening complication in the postoperative patient. In the last 7 years, we have treated four children in whom necrotizing fasciitis developed after appendectomy for ruptured appendix, bilateral inguinal herniorrhaphy, or gastrostomy closure. These four patients and seven well-described children from the literature with necrotizing fasciitis following surgery form the basis of this review. The ages ranged from six days to 15 years (mean 4.5 years). There were eight boys and three girls. There were five clean, five clean-contaminated, and one contaminated surgical procedures. No patient had evidence of malignancy or diabetes. Two of our four patients had evidence of failure to thrive. Only one patient had an intraabdominal abscess. In ten, the infection started in the abdominal wall; in one, the infection started in the chest wall. In our four patients, three had neutropenia and fever, four had tachycardia, and two had wound crepitation and radiographic evidence of subcutaneous gas. Cultures of all ten wounds were positive for bacteria; six were positive for more than one organism. Blood culture results were positive in five of five patients who died and in only two of five patients who survived. All survivors had wide surgical debridement and were treated with broad-spectrum antibiotics. The mortality rate was 45% in the whole series.
