Necrotizing Soft Tissue Infections
- Necrotizing soft tissue infections: delayed surgical treatment is associated with increased number of surgical debridements and morbidity.
- Kobayashi L, Konstantinidis A, Shackelford S, Chan LS, Talving P, Inaba K, Demetriades D.
- J Trauma. 2011 Nov;71(5):1400-5.
Rationale for inclusion: This more recent study found that a delay in surgical intervention >12 hours contributes to higher mortality, septic shock an renal failure, and is associated with an increased number of debridements than patients whose initial debridement is <12 hours after admission. This confirms that early initial debridement leads to improved outcomes in NSTI.

Rationale for inclusion: While CT scan should not delay operative intervention for NSTI, this study finds that it may be a useful adjunct for ruling out the diagnosis of a necrotizing infection.

Rationale for inclusion: This study identifies risk factors for mortality, including APACHE II score and lactate levels. It also focuses on the benefit of primary management by an EGS service to facilitate prompt surgical intervention.

- Am J Surg. 2005 Apr;189(4):462-6.
Rationale for inclusion: This literature review does not find consistent evidence to support the routine use of HBO as an adjunctive therapy in the management of NSTI. These findings have since been corroborated in a recent Cochrane review that failed to locate relevant clinical evidence to support or refute the effectiveness of HBOT in the management of necrotizing fasciitis. Good quality clinical trials are needed to define the role of HBOT in the treatment of individuals with necrotizing fasciitis.

- Arch Surg. 2005 Feb;140(2):151-7; discussion 158.
Rationale for inclusion: One of the largest cohort studies to determine predictors of mortality that include leukocytosis, elevated creatinine, presence of heart disease, shock and Clostridial infection.

- Wong CH, Khin LW, Heng KS, Tan KC, Low CO.
- Crit Care Med. 2004 Jul;32(7):1535-41.
Rationale for inclusion: This well cited study discusses one of the most widely used scoring systems to assist with early diagnosis of NSTI. This validated scoring system is based on laboratory values found to be independent predictors of disease and can be used to guide management.

- Wall DB, Klein SR, Black S, de Virgilio C.
- J Am Coll Surg. 2000 Sep;191(3):227-31.
Rationale for inclusion: Although this is a smaller retrospective review to help distinguish between necrotizing and non-necrotizing infection, the model is simple and highly sensitive with a NPV of 99% for diagnosing necrotizing infection. This tool may be useful when other laboratory parameters (such as those required for the LRINEC score) are not available.

- Am Surg. 1998 May;64(5):397-400; discussion 400-1.
Rationale for inclusion: Although this is a smaller retrospective review, the authors found that early surgical debridement leads to a significant reduction in mortality, highlighting the importance of early recognition and expeditious initial debridement in the management of NSTI.
