hyperglycemic crisis 2 Flashcards
how often should blood glucose be monitored to prevent hypoglycemia
every 1-2 hours
how is hyperchloremic metabolic acidosis avoided
switch fluid to half normal NS when rehydrated
what can occur is blood glucose is decreased too quickly
cerebral edema
hyperglycemia is associated with worse outcomes, including:
- impaired wound healing
- increased infection rates
- increased mortality in certain patients
glucose production occurs via what?
gluconeogenesis and glycogenolysis
what is the metabolic effect of cortisol
increased gluconeogenesis
what was the first land mark trial that looked at glucose in critically ill patients
leuven surgical trial
what wre the results of the Leuven medical trial
intensive insulin therapy reduced morbidity but not mortality among all patients in medical ICU
what were the results of the NICE_SUGAR study
intensive glucose control (81-108) increased mortality in ICU; target of 180 reduced mortality
what is the best target blood glucose in the ICU
140-180
what is systemic vascular resistance
resistance of flow of blood in the peripheral arterial vessels
what is the term for the stretched condition of the heart muscle at the end of diastole
preload
what is the term for the force against which the ventricle contracts that is contributed to by SVR
afterload
what is the term for the volume of blood ejected from the left side of the heart in 1 minute
cardiac output
what is mean arterial pressure
average pressure in an artery over a cardiac cycle
