[Severe necrotizing fasciitis]
1Department Chirurgie, Universitätsspital Zürich.
Abstract:
The pathophysiology of necrotizing fasciitis remains unclear in patients with no apparent immunologic disorders. Between 1987 and 1990 we treated six patients with necrotizing fascitis and septic-toxic multiple organ failure, three patients survived. The mean age was 38 years (25-62). In all patients the primary bacteriological examination revealed streptococcus. Between the first symptoms and an adequate therapy were 4 days in surviving patients and 7 days in patients who died. Four patients showed spread of the gangrene into the adjacent tissue: muscles (n = 3), bowel (n = 2), mediastinum (n = 1). Adequate débridement was not possible or not performed in patients with spread into the abdominal cavity or the mediastinum. These patients did not survive. The duration of intensive care treatment in surviving patients were 14 to 78 days. We conclude that survival of patients with severe necrotizing fasciitis is influenced by the delay before adequate treatment, the localisation of the gangrene and intensive care facilities.
Insights
Early treatment and localized gangrene improve survival in severe necrotizing fasciitis patients. Prompt intervention and surgical debridement are critical for managing this aggressive streptococcus infection.
Area of Science:
- Infectious Diseases
- Surgical Pathology
Background:
- Necrotizing fasciitis pathophysiology is poorly understood, especially in immunocompetent individuals.
- Streptococcus is a common pathogen in severe necrotizing fasciitis cases.
Observation:
- Six patients with necrotizing fasciitis and septic-toxic multiple organ failure were treated between 1987 and 1990.
- Three patients survived, with a mean age of 38 years.
- Gangrene spread to adjacent tissues (muscles, bowel, mediastinum) in four patients.
Findings:
- Survival was linked to a shorter delay (4 days) between symptom onset and adequate therapy compared to non-survivors (7 days).
- Inadequate debridement due to extensive spread into the abdomen or mediastinum correlated with mortality.
- Intensive care duration for survivors ranged from 14 to 78 days.
Implications:
- Timely diagnosis and aggressive surgical debridement are crucial for improving necrotizing fasciitis outcomes.
- The extent and location of gangrene significantly impact patient prognosis.
- Advanced intensive care management is vital for supporting critically ill patients with necrotizing fasciitis.
