How is DKA defined?
How is DKA managed?
How much fluid deficit are pts in DKA usually?
100ml/kg
Why do we give insulin in DKA?
Clear ketones, suppress ketogenesis and avoid avoid hypoglycaemia
How much insulin do you give in DKA?
When do you give dextrose in DKA?
when CBG <14
When would you switch to variable rate insulin infusion in DKA?
When ketones <0.6
pH >7.3
HCO3 >18
When do you measure hourly in DKA?
CBG
Blood ketones
Venous bicarbonate
K+
When is DKA resolved?
When blood ketones <0.3mmol/l
and venous pH >7.3
How long do you give IV insulin for in DKA, when patient has started back on usual sc insulin?
1 hour to make sure CBG’s are stable without huge variability.
signs of euglycaemic DKA?
Acidosis
Ketonaemia
normal/slightly raised CBG
Why does euglycaemic DKA occur?
As a result of insulin deficiency/inactivity accompanied by an increase in counter regulartory hormones.
What medications can cause Euglycaemic DKA?
What are the characteristic features of HHS?
How is HHS managed?
How long does resolution of HHS take?
up to 72 hours

When would you admit a patient with high BP?
How would you treat a HTN emergency?
What is the drug class of nifedipine?
dihydropyridine calcium channel blocker
What is there a risk of if MAP is decreased too quickly?

How is phaeochromocytoma managed?
What is the reticular system?
Essence of awareness/consciousness
