Necrotising fasciitis

Infection/Condition and Likely Organism

Suggested Treatment

Comments

Preferred Treatment

Alternative Treatment

Necrotising fasciitis

Streptococcus spp.:

Group A Streptococcus (GABHS) Other

Streptococcus spp.

Staphylococcal:

Staphylococcal aureus

(MSSA and CA MRSA)

Streptococcal necrotising fasciitis: Benzylpenicillin 200,000-300,000units/kg/ day IV in 4-6 divided doses

PLUS

Clindamycin 20-40mg/kg/ day IV in 3-4 divided doses max. 2.7gm/day)

 

50% of patients have associated streptococcal toxic shock syndrome (STSS).

Aggressive surgical debridement of the deep-seated infection is the mainstay of therapy.

 

Combination therapy is needed with Clindamycin to block toxin production whether or not patient manifests toxic shock syndrome. Tissues should be sent for Gram staining and C&S.

IVIG can be used as an adjunct, typically at 1 gm/kg on Day 1, followed by 0.5mg/kg on 1-2 subsequent days.

Staphylococcal necrotising fasciitis:

Cloxacillin 200mg/kg/day IV in 4-6 divided doses

PLUS

Clindamycin 20-40mg/kg/ day IV (max. 2.7gm/day) in 3-4 divided doses

If CA-MRSA is suspected: Vancomycin 60mg/kg/day IV in 3-4 divided doses (max. 2gm/day)
