The following statement(s) is/are true for necrotizing fasciitis.
A. Mortality rates as high as 40%B. The infection involves only the superficial fascia, sparing the deep muscular fascia
C. An impaired immune system is a common factor predisposing to this condition
D. The infection is usually polymicrobial
E. Necrotizing fasciitis is most likely to develop in the face of impaired fascial blood supply
The Answer
is: A. Mortality rates as high as 40%, C. An impaired immune system is a co tor
predisposing to this condition, D. The infection is usually polymicrobial. E.
Necrotizing fascitis is most likely to develop in face of impaired fascial
blood supply
Necrotizing fascitis is an uncommon complication of
the deep and superficial fascia that is as with mortality as high as 40% in
many cases. Many underlying disease processes predispose to necrotizing
fascitis, three common factors are invariably present:
1) impairment of the immune system; 2) compromise of
fascial blood supply
3) presence of microorganisms [MCQ] – staph, strept,
enteric bacteria, and few gm –ve (m/c is polymicrobial)
Some microorganisms possess virulence factors that, in
conjugation with an underlying host predisposition, allow the necrotic process
to occur without dependence on other bacteria. Example: clostridia,
Pseudomonas, and Aeromonas.
