Hypoglycaemia Flashcards
describe how hypoglycaemia impacts a patients hospital experience
increased length of hospital stay and higher mortality both during and after admission
how is hypoglycaemia defined for patients undergoing diabetes treatment
blood glucose < 4mmol/L
what types of treatment is hypoglycaemia a complication of
insulin therapy and drug therapy with drugs such as gliclazide, glipizide, glimepiride, glibenclamide
what is hypoglycaemia caused by
a mismatch between plasma insulin and glucose conc.
what is the physiological mechanism the body responds to hypoglycaemia with
defence reactions called counter regulation
what hormones are involved in the autonomic response to hypoglycaemia
adrenaline, glucagon, cortisol, growth hormone
what is the livers physiological response to hypoglycaemia
liver acts as a glucose store, liver will release glucose into blood when levels are low
how can glucose release into the blood be impaired in hypoglycaemia
when glycogen levels are low
what types of patients likely have low glycogen
malnourished, have recurrent hypoglycaemia, have severe liver disease, those who have consumed excessive alcohol
what autonomic symptoms can be felt in patients with hypoglycaemia
trembling, anxiety, palpitations, numbness or tingling(peripheries/lips), irritability, hunger, pale/sweaty, afraid
what types of symptoms are felt first in hypoglycaemia
autonomic
when do neuroglycopenic symptoms of hypoglycaemia occur
as blood glucose falls towards 2mmol/L and brain becomes short of glucose
what neuroglycopenic symptoms can be felt by patients with hypoglycaemia
problems with weakness/concentration/co-ordination/vision, slurred speech, loss of consciousness, seizures
what treatment is used for hypoglycaemia patients who can swallow
15-20g of quick acting carbs
eg 60ml glucojuice, 4-5 glucotabs or 150-200ml fruit juice
(avoid fruit in renal failure)
what treatment is used for hypoglycaemia patients who can swallow but are drowsy or confused
1.5 - 2 tubes of glucose gel, squeezed into mouth and between gums
