Pneumonia Flashcards
most common pathogen pneumonia
s pneumoniae
2nd most common pathogen pneumoniae
mycoplasma pneumonia
this bug colonizes in pts with COPD and CF
H. influenza
this bug is common in young children and elderly
moraxella catarrhalis
this bug is associated with necrotizing and more severe forms of CAP
CA-MRSA
common cause of pneumonia in children
viral
common bug viral pneumonia children
RSV, influenza A, parainfluenza
viral bugs pneumonia adults
much less common, influenza A&B, adenovirus
aspiration pneumonia- oral contents include what bugs
variety of anaerobesL bacteroides, fusobacterium, prevotella, anaerobic gram cocci
aspiration pneumonia- gastric contents include
gram negative bacilli and s aureus
etiology HAP/VAP
aerobic gram neg: pseudomonas, e coli, klebsialla, acinetobacter
gram positive: MRSA
anaerobes RARE
gold standard for diagnosing pneumonia
CXR reveals infiltrates
what is required for all patients hospitalized with pneumonia
BLOOD CULTURES
pt had a CURB-65 score of 3. what to do?
consider ICU
CURB stands for
Confusion BUN (over 7) RR (over 30) BP (sys less than 90, dia less than 60) Age (over 65)
To dx HAP or VAP, the CXR needs to reveal infiltrates, plus two of the following:
temp over 38C
leukocytosis or leukopenia
purulent secretions
cultures with pathogens
treatment of aspiration pneumonia (oral)
PCN G, ampi/sulb, clindamycin
treatment of aspiration pneumonia (gastric)
ampi/sulbac, amox/clav, piper/tazo
treatment for early onset HAP
3rd generation cephalosporin plus macrolide or a respiratory fluoroquin
treatment of early onset VAP, no risk for MDR
cefotaxime
ceftriaxone
amp/sulb
antipneumo fluoro
add these two ab if suspect MRSA
