SSTI's Flashcards
who gets complicated infections
DM, burns, pressure ulcers, traumatic/surgical wounds
*more commonly polymicrobial
polymicrobial infections often include
anaerobes and gram negative bacilli such as E. coli and pseudomonas aeruginosa
pt.’s with dm are extremely at risk for
fulminant SSTI’s by staph aureus, streptococcus group A and C. diff
according to sweatman MRSA is usually sensitive to
bactrim
clinda
tetracylclines (doxycycline or minocycline)
“HA-MRSA is usually not”
1st tc for a simple abcess
drainage…often this is enough
never use which drug class to treat SSTI’s
floroquinolones
if pt. suspected to have MRSA, serious skin infection, what are your agents
Vanc + gentamicin
linezolid
daptomycin
(ceftaroline)–> according to cross
COMPLICATED (POLYMICROBIAL INFECTION) …WHAT IS YOUR TX
one of these (vanc, dapto, linezolid)
+
IV carbapenen or pip/tazo
only beta lactam with activity against MRSA
is coinciding P. aeruginosa not suspected
ceftaroline (cephalosporin)
OUTPATIENT: regular (non MRSA staph infections should get
amoxicillin is possible–> but probaby not so
dicloxacillin
cephalexin (ist gen)…again i would be cautitous about this
must not be in high risk area, no house members with boils, not known to be colonized
regular non MRSA infeciton…but sever enough to require hospitalization
IV nafcillin, oxacillin, cefazolin,
requiring hospitalization but non MRSA and alergic to beta lactams
vanc + gent
clindamycin
complicated infections (poly microbial) but still unlikely to contain MRSA
ampicillin/sulbactam
pip/tazo
ticarcillin/calculonic acid
meropenem
IF you suspedt GAS of C. diff
clinda + pencillin G/V
100% of strep remains susceptible to
penicilin
