antibiotics Flashcards
what are the four types of infective endocarditis
native valve endocarditis
intravenous drug use
prosthetic valve
gut bound bacterial endocarditis
what microbacteria causes native valve endocarditis
viridans streptococci
what causes intravenous drug use endocarditis
staphylococcus aureus
what causes prosthetic valve endocarditis
staphylococcus epidermidis
what causes gut bound bacterial endocarditis
enterococcus faecalis and streptococcus boulis
antibiotic for native valve endocarditis
amoxicillin IV
Gentamicin IV
antibiotic for intravenous drug use endocarditis
fluoxacillin IV
antibiotic for prosthetic valve endocarditis
vancomycin
gentamycin IV
Rifampicin PO
antibiotic for gut bound bacterial endocarditis
amoxicillin
vancomycin and gentamicin IV
antibiotic for viridans streptococci
amoxicillin IV
gentamicin IV
antibiotic for staphylococcus aureus
Fluoxacillin IV
antibiotic for staphylococcus epidermis
vancomycin
gentamicin iv
rifampicin PO
antibiotic for enterococcus faecalis and streptococcus boulis
amoxicillin
vancomycin and gentamicin IV
three main types of pneumonia
community acquired
hospital acquired
aspiration
how is the severity of pneumonia graded
CURB 65 score
antibiotics for mild/moderate (0-2) pneumonia
amoxicillin IV/PO 5 days
or doxycycline PO (penicillin allergy)
antibiotics for severe (3-5) pneumonia
Co-amoxiclav IV and Doxycycline PO
or Levofloxacin IV 500mg (penicillin allergy)
antibiotics for severe and ICU/NBM pneumonia
Co-amoxiclav IV and Clarithromycin IV 500mg
or Levofloxacin IV 500mg (penicillin allergy)
antibiotics for non-severe HA pneumonia
amoxicillin
or (penicillin allergy)
doxycycline
antibiotics for severe HA pneumonia
amoxicillin and gentamicin
or (P.A.)
co-trimoxazole +/- gentamicin
antibiotics for previous ICU/MRSA HA pneumonia
seek help bitch
antibiotics for non severe aspiration pneumonia
Amoxicillin and metronidazole
or (PA)
doxycycline and metronidazole
antibiotics for severe aspiration pneumonia
amoxicillin and metronidazole and gentramicin
or (PA)
replace amoxicillin w doxycycline/clarithromycin
effect of antibiotics on exacerbations of asthma/bronchitis?
no real effect clinically
should be considered for the elderly
when to give antibiotics for COPD
increased sputum purulence
signs of consolidation on XCR
signs of pneumonia
first line antibiotics for copd/asthma/bronchitis exacerbation
Amoxicillin
second line antibiotics for copd/asthma/bronchitis exacerbation
doxycycline
non severe symptoms of clostridium difficile
just diarrhea
severe symptoms of clostridium difficile infection
abdominal tenderness
Albumin >3 g/dL
WBC> 15,000
antibiotics for non severe clostridium difficile infection
Metronidazole
antibiotics for severe clostridium difficile infection
Vancomycin
+/- Metronidazole
antibiotics for peritonisis/biliary tract/intra abdominal infection
amoxicillin and metronidazole and gentamicin
or (PA)
vancomycin and metronidazole and gentamicin
next step after first line for peritonitis/biliary tract/intra-abdominal infection
step down to
co-trimoxazole and metronidazole
proven spontaneous bacterial peritonitis mild disease
co-trimoxazole
proven spontaneous bacterial peritonitis severe disease
piperacillin/tazobactam
