Q

Why is urgent surgical debridement necessary in necrotising fasciitis?

A

Antibiotics are unable to penetrate infected necrotic Gussie
Due to the thrombogenic nature of NF, early and aggressive surgical debridement remains the priority
Timing and adequacy of the initial debridement is a major determinant of mortality
