wk 5 1 GI infection control - GI sepsis Flashcards
perforation of which organ will lead to colonisation by e.coli, klesbiella spp., strep. faeclis and anaerobes
gall bladder
t/f meckels diverticulum would be colonised by e.coli, clostridium spp. and pseudomonas aeruginosa
false
e.coli
colistridium spp.
anaerobes would colonise a meckels diverticulum
what 5 organisms would colonise a perforated large bowel
clostridium spp. strep faecalis e.coli proteus spp. pseudonomas aeruginosa
5 incidences where e.coli could colonise GI tract
perforated peptic ulcer gallbladder large bowel meckels diverticulum bladder
other than e.coli, which 2 organisisms could colonise the bladder
proteus spp.
strep faecalis
3 areas where strep faecalis could colonise
perforated gallbladder
large bowel
bladder
t/f vagina infectioin could be colonised by lactobacillus spp., anaerobes, peptostrep spp. and coliforms
true
define cholangitis
infection in common bile duct - bile stone
entercoccus faecalis and faecium are 2 gram +ve cocci which may infect opportunisticly, which one is more common, more resistant
faecalis - commin
faecium - resistant
antibiotics for enterococcus in GI
amoxicillin (vanco if pen allergic)
switch to cotrimoxazole if persistent
which type of pathogen would lead to gas gangrene q
clostridium pertingens
3 organisms which are cocci and oval in shape (gram+ve)
strep
peptostrep
entero
staphyloccocus
micrococcus
petococcus
t/f these are gram +ve cocci and round in clusters q
true
2 organisms which are gram+ve bacilli and spore-bearing
bacillus
clostridium
t/f campylobacter are gram+ve curved shape
false
gram-ve
pseudomonas
gram-ve uniform bacilli
peritonitis/biliary tract and intra-abdominal all recieve the same treatment, spawning 7-10 days. which 3 antibiotics are given
IV - amoxicillin, metronidazole, gentamicin (vancomycin if pen. allergic)
t/f acute gastritis and pancreatitis are unlikely to be given antibiotics
false
gastroenteritis
pancreatitis
unlikely to affect outcome
likely treatment for a severe clostridium difficile infection
vancomycin +/- metronidazole
(10days)
if non-severe - metronidazole
it can be difficult to determine the diagnosis if there is an unusual immune response, microbe response or site of infection. give examples of when each would apply
host - age, immunosuppressed, co-morbidity drug genetics
microbe- virulence expression, intracellular predilation for certain sites
site - deep seated
vague symptoms
BUFALO is a sepesi intervention too, what does the pneumonic stand for
Blood cultures + septic screen, U&E Urine output - hourly Fluid resuscitation Antibiotics IV Lactate measurement Oxygen - hypoxic
2 quadrants where pain may be present in pneumonia
R+LUQ
t/f large abscesses cannot be treated with antibiotics
true - no blood supply
small - can be treated with antibiotics but large collections need incision and drainage
what to consider if spontaneous peritonitis, what if its secondary
abscess
bacterial spread
t/f all anaerobes are resistant to metronidazole
true
drug choice for sepsis and enterococci in gi tract
amoxiciloin
cotrimoxazole - if amox contras/ oral switch
vancomycin may be used
drug choice for sepsis and coliforms
gentamicin
aztreonam - genta conteas,
co-trimoxazole for oral switch
t/f gentamicin is drug choice for sepsis and anaerobes
false
metronidazole
