Group A strep and SA- IV FLUCLOX
How to treat Necrotising fasciitis
Broad spectrum high dose parenteral therapy Fluclox/ benzylpenicillin/clindamycin/ gent/ metro
surgical debridement often needed for source control

Prosthetic joints and CVC line - s aureus, coag -ve staph, strep.
Signs of CVC line infection
may be systemically unwell because of blood stream sepsis, may have erythema and pain, discharge
How to manage CVC related infection
remove and culture + ABx
