Sepsis Flashcards
microbio of sepsis form peritonitis
anaerobes (eg ecoli)
how does the infection spread in sepsis
leaky blood vessels
what is septicaemia
a word that isnt used anymore bc its too vague lol
not the right answer in exams
what is bacteraemia
bacteria in the blood
SIRS criteria
2 or more of temp >38 or <36 (fever) heart rate >90 (tachycardia) resp rate >20 (tachypnoea) WCC >12000mm3
sepsis criteria
SIRS with an infectious cause
sepsis shock definition
sepsis with unresponsive hypotension (to fluids) = higher risk of mortality
a NEWS score of what with ?infection should make you think sepsis
5
how quickly should you administer ‘BUFALO’ for sepsis to prevent complications
1 hour
BUFALO - B
blood cultures (2 sets)
BUFALO - U
urine output
BUFALO - F
fluids
0.9% saline (sodium chloride) 500mls stat bolus (then keep adding 500ml boluses until necessary)
BUFALO - A
antibiotics
BUFALO - L
lactate (<1.8 is normal)
BUFALO - O
oxygen (target sats 94-98%)
why do you monitor urine output in sepsis
kidney damage/hypoperfusion = AKI
target urine output for someone with sepsis
0.5ml/kg/hour
if someone with sepsis was anaemic, what might you give them instead of saline for fluids
blood
which microbio cause of sepsis would you give PO antibiotics in (all others are IV)
c diff
antibiotic for coliform cause of sepsis
gentamicin
which screening tool is used to measure prognosis in sepsis
qSOFA
qSOFA criteria
resp rate >22
altered mental state (AVPU/GCS<14)
systolic bp <100
prognosis of someone with a qSOFA of 1
2-3% mortality
prognosis of someone with a qSOFA of 2/3
10% mortality
