DKA Flashcards
what are some early signs of DKA ?
feeling very thirsty
urinating often
high glucose level
high ketone level in urine
what are some later extreme signs for DKA ?
feeling weak/ constantly sleepy dry/ flushed skin nausea vomitting and pain in abdomen difficulty in breathing fruity smelling breath
what are the 3 things used to diagnose DKA ?
- hyperglycemia
- anion gap metabolic acidosis, more than 10
- ketonemia (presence of ketones)
what is ketone broken down into?
beta hydroxybutyrate and acetoacetate
what are some precipitating factors of DKA ?
- infection (30%-50%)
2. discontinuation or inadequate insulin therapy
what are some management of DKA ?
provision of fluid (restore dehydration)
provision of insulin (stop over production of ketones)
replace electrolyte deficits
treat any underlying precipitating cause
monitor any complications
what is the goal for fluid replacement for DKA ?
- expansion of intravascular, interstitial and intracellular volume
- ensure sufficient renal perfusion
what is one thing to take note when replacing fluids in the body?
patient with renal or cardiac compromise need to be monitored closely to prevent fluid overload
if there is severe hypovolemia ? what to do?
administer 0.9% Nacl 1 litre in an hour
what to do when there is mild dehydration?
first check the Na level
IF Na level is high- nomral what to do?
0.45% Nacl (200-500ml) in an hour
what to do when serum level is low?
0.9% NAcal (250-500ml ) in an hour
what is the ideal potassium level to keep for patients ?
4-5
usually added even though it is within the level
what to do when potassium level is less than 3.3 ?
hold insulin and give 20-300
until K is more than 3.3
what to do when K is 3.3-5.2 ?
give 20-30 in each liter of IV to keep serum K between 4-5
