Glycémie anormale, diabète Flashcards
The most common cuase of hypoglycemia in a previousy stable, well-controlled diabetic pt who has not changed his diet or insulin dosage is..?
db renal dz
(néphropathie db)
*insuline exogène est métabolisée a/n rénale, si IRC, temps de demi/vie insuline aug, donc dim besoin insuline, + hypoglycémie si dosage non ajusté
Triade hypoglycémie?
Triade de Whipple:
sx are known or likely to be caused by hypoglycemia
a low plasma glcose measured at the time of sx
relief of sx when the glucose is raised to N
[…] is a non-sulfonylurea agent that interacts with a diferrent portion of the sulfonylurea receptor to stimulate insule secretion. It may cause hypoglycemia.
Repaglinide
test #1 pour dépister néphropathie db?
recherche de microalbuminurie
–> ratio albu:créat
The use of a long-acting insulun provides flexibility with the timing of injections and enhances compliance, which in turn could […]?
improve control of the pt DB, deresse the risk of hypoglycemia,
and imprve overall pt satisfaction
gestion pré-op de Db si chx: cardiothoracique, ortho ou neuro?
*considered maor surgeries
MTF should be stopped the evening before the chx
It should not be taken the day of chx
Premixed insulin (such as biphasic insulin Aspart 70/30) should be taken as 80% usual nighttime dose
un signe insulinorésistance?
acanthosis nigricans (DB type II)
For geriatric pt in long-terme car facilities, the predictable glucose control of […] is the best approach to consider intially.
insulin glargine
[…] is contraindicated in pt with liver dysfct, IC, and those with renal dysfct (ClCr < 30 ml/min)
Metformin
