bicarbonate < __ mmol/L or venous pH < ___
biochemical diagnosis of DKA:
ketonaemia > 3mmol/L or significant ketonuria
blood glucose > 11 mmol/L or known DM
bicarbonate < 15 mmol/L or venous pH < 7.3
name the precipitants of DKA
newly diagnosed
infection
illicit drug and alcohol use
poor self management
name the 2 osmotic related typical symptoms and signs of DKA
thirst and polyuria
dehydration
name the 4 ketone body related typical symptoms and signs of DKA
flushed
vomiting
abdominal pain
breathless - kussmaul’s respiration
classical biochemistry of DKA at diagnosis:
glucose - potassium - creatinine - sodium - lactate - blood ketones - bicarbonate - amylase - WBC -
glucose - median of 40mmol/L potassium - raised creatinine - raised sodium - low lactate - raised blood ketones - above 5 bicarbonate - <10 amylase - raised WBC - median 25
