What key things should in include in a history for a collapsed patient?
What is the neurological approach?
What are the different parts of the brain where a problem could be?
What neurological problems could you get in the brainstem?
What neurological causes are there of impaired consciousness?
What metabolic causes are there of impaired consciousness?
What diagnoses should you always consider in a neurological patient?
What could a fluctuating GCS indicate?
What spontaneous movements could you observe in an unconscious patient?
What is the approach to the acute neurological evaluation?
What quick cognitive assessment would you do in a neurological evaluation?
What do you check for in the eyes for a neurological evaluation?
How do you check for brainstem reflexes?
What special tests could you conduct for a neurological evaluation?
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.
