sepsis Flashcards
what is sepsis
dysregulated host response to infection leading to life threatening end organ dysfunction
what is septic shock
sepsis with evidence of cardiovascular dysfunction
hypotension is a late sign
how to recognise sepsis
should be considered in a patient with suspected or proven infection and/or fever/hypothermia
plus
any sign of impaired tissue perfusion
signs of impaired tisssue perfusion
tachycardia
bradycardia
cold shock: raised CRT, cool peripheries, cool or mottled skin, reduced peripheral pulses, narrow pulse pressure
warm shock: reduced CRT, boudning pulses, wide pulse pressure
altered level of consciousness
new onset end organ dysfunction
evolving petechial or purpuric rash
unexplained pain
cold shock
raised CRT, cool peripheries, cool or mottled skin, reduced peripheral pulses, narrow pulse pressure
warm shock
reduced CRT, boudning pulses, wide pulse pressure
inital management of sepsis
call for help
apply oxygen
establish vascular access
take blood (should not delay Abs)
commence Abs
commence fluid resus
correct hypoglycaemia if present
how to call for help
in ED: call consultant, move patient to resus room, consider PCC review
on ward: follow sepsis recognition escalation pathway on the observation and response chart
what should you send the bloods for
blood culture, lactate (venous blood gas), FBC, ureaa, electrolytes and creatinine, LFTs, coagulation profile, and CRP
ongoing resus
continue fluid resus with repeat boluses 10-20ml/kg of sodium chloride 0.9% as needed
if circulatory failure persists following 40ml/kg saline
PCC review
consider peripheral ionotropes
consider further fluid bolus
prepare for intubation
arrange transfer to PCC
consider hydrocortisone for fluid refractory, catecholamine resistant shock
high risk groups
infants less than 3 months of age
immunosuppression due to chemo, long term steroids, other immunosuppresssants, asplenia and other chronic medical conditions
unimmunissed/incomplete immunisation
children with central venous access devices, indwelling medical devices
recent surgery, burn or wound
rural, remote or socioeconomic issues
re-presentation
vascular accesss
if IV access cannot be obtained, opt for intraosseous access
it may be appropriate to opt for intraosseous acces initially in critically unwell patient or for whom access is clearly going to be difficult
blood tests
hould be taken at the time of IV access, wth priority given to venous blood gas and blood culture collection
antibiotic administration and fluid resus mut not be delayed by repeated attempts to collect blood samples
blood lactate
a normal blood lactate level does not exclude sepsis
there is an association between elevated blood lactate and adverse outcomes in paediatric septic shock
