serious bacterial infections Flashcards
what is easy to miss in febrile children
meningitis, UTI, bacteremia, occult pneumonia
abdominal pain can predominate
occult lobar pneumonia
which are hemotogenously spread
bacteremia, endocarditis, meningitis, osteomyelitis, septic srthritis
which are spread via direct invasion
UTI-pyelonephritis
pneumonia-sinusitis-mastoiditis
cellulitis-
what are the diagnostic tests you should get
blood culture, CMP, CBC c/ diff, urine, CSF culture whe stable
what are the most common etiologies of bacteremia/sepsis in children
N meningitidis, S pneumoniae
less common S aureus, S pyogens GAS, gram neg
what is the treatment of sepsis
Vancomycin and ceftriaxone - modify when culture comes back
for what pathogens should you prophylax close contacts
Neisseria meningitidis (PO -cipro, IM ceftriaxone, PO rifampin) Haemophilus influenza type B (PO- rifampin)
you receive a urine culture: E coli
what is it susceptible to
ampicillin, TMP-SMX, cephazolin, ceftriaxone, ciprofloxacin
T/F most UTI in young children are pyelonephritis
true
what are the common etiologies of bacterial meningitis
Spneumo, N mening, Hib
what is the empiric tx for bacterial meningitis
cefotaxime or ceftriaxone + vancomycin
what are common etiologies of bacterial cellulitis
Staph aureus, Strep pyogenes GAS
what is the empiric tx for bacterial cellulitis
PO-augmentin; IV oxacillin/nafcillin
1st gen cephalospori: cephalexin; IV cefazolin
what if MRSA is suspected
clinamycin, vanco if really sick
a blood culture grows Strep pnumo - resistant to PCN what do you give
ceftriaxone, cefuroxime, vancomycin
pneumo eti in infant
GBS, E coli, chlamydia, pertussis, viral -bronchiolitis
infant pneumo eti
S pneumo, Hflu (not Hib), moraxella, GAS, pertussis
empiric Abx for pneumo
outpt: amoxicillin
inpt: caftriaxone or ampicillin
atypical i.e myco- azithromycin
most common eti of septic arthritis & osteomyelitis
Staph aureus, Strep pyogens
empiric tx for SA & OA
IV clinda
initial empiric tx for SA & OA
IV clinda
