exam 1 hyperglycemic crises pp Flashcards
DKA more seen in
T1DM
younger ppl
recurrent in hospitalized pts
HHS more seen in
T2DM
higher mortality rate than DKA
older ppl
DKA can present in T2DM when
under stress
pts taking SGLT2 that leads to euglycemic asymptomatic DKA
T1DM risk factors DKA
younger age
history or hyperglycemia and hypoglycemic crises
kidney disease
neuropathy
depression
smoking
alcohol and drug use
high A1C and SDOH
T2DM risk factors DKA
younger age
history or hyperglycemia and hypoglycemic crises
comorbidities
elevated A1C and SDOH
socioeconomic risk factors DKA
low income
area level deprivation
housing insecurity
lack of insurance or underinsured
food insecurity
SDOH
mental health conditions
precipitating factors for DKA
omission or insufficient use of insulin
infections
alcohol or drug use
PE
MI
stroke
pancreatitis
trauma
precipitating factors for HHS
infection
acute CV events
MI
surgery
acute pancreatitis
heat stroke
drugs that can precipitate DKA and HHS
phenytoin
clozapine
olanzapine
calcineurin inhibitors
glucocorticoids
cimetidine
SGLT2
thiazides
cocaine
absolute or relative insulin deficiency
elevation of counter regulatory hormones (glucagon, EPI, NE, cortisol, growth hormone)
DKA
DKA presentation
hyperglycemic
volume depletion (dehydrated)- decreased urine output, dry mouth, polyuria, polydipsia
N/V
abdominal pain
DKA diagnosis criteria
glucose
ketosis
metabolic acidosis
> 200
3
pH <7.3 OR bicarb <18
mild DKA acidosis
pH 7.25-7.3
bicarb 15-18
moderate DKA acidosis
pH 7-7.25
bicarb 10-15
severe DKA acidosis
pH,7
bicarb<10
decreased pH
decreased serum bicarb
metabolic acidosis
metabolic acidosis respiratory compensation
Kussmaul respirations:
rapid breathing
fruity breath
anion gap equation
Na-Cl-HCO3
>12 is consistent with metabolic acidosis
IV fluids used
0.9% NS
LR
when glucose reaches <250 what should be added
5 or 10% dextrose
euglycemic DKA needs what fluids when starting insulin
0.9% NS OR LR AND
5 OR 10% dextrose
mild DKA insulin therapy
rapid insulin SC
0.1 units/kg bolus then every hour
when glucose reaches <250 insulin 0.05 units/kg/hr
moderate-severe DKA insulin therapy
short acting insulin IV
0.1 units/kg bolus then 0.1 units/kg/hr infusion
when glucose reaches <250 insulin 0.05 units/kg/hr
DKA target glucose
<200
