Hypoglycaemia Flashcards
What are the symptoms of hypoglycaemia?
- Difficulty concentration
- Confusion, unconsciousness
- Change of behaviour
- Slurring of speech & convulsions
- Shaking & trembling
- Sweating
- Pin & needles in lips n tongue
- Hunger
- Palpitation
- Headache (occasionally)
- Double vision
What drug is most likely to cause hypoglycaemia?
- Sulphonylurea
- Insulin
Explain the management for hypoglycaemia?
Blood glucose is over 4mmol/l with hypo symptoms - have a small carb snack like bread/normal meal
If blood glucose is less than 4mmol/l with/without symptoms; and conscious and can swallow - give oral glucose e.g. glucogel
After 30-45 minutes or 3 cycles:
If blood glucose is less than 4mmol/l and still conscious - give IM glucagon or IV glucose 10% infusion (and thiamine if alcoholic patient)
If no better, it’s an emergency
if glucose levels is still less than 4mmol/l and unconscious - give IM glucagon or IV glucose 10% / 20% infusion
(if glucagon is not effective after 10 minutes (or is unsuitable) then give IV glucose 10% / IV 20%)
What’s an alterantive to glucogel, that you can give to patients with 4mmol/l or less, with or without symptoms?
- Glucose liquid
- Glucose tablets
- Dextrogel
- Pure fruit
- Dissolved sugar (sucose)
Which patients cannot take sucrose?
Patients taking acarbose
Which patients should not take orange juice?
Patients following a low potassium diet due to chronic kidney disease
Why are chocolates and biscuits not given for hypoglycaemia?
Because they have a low sugar content, and high fat content can delay gastric emptying
Explain the three cycles you can do for hypoglycaemia?
Eat, wait 15 mins.
Repeat for a max of 3 times in total.
What should be done after glucose concentration is over 4mmol/l?
A snack containing a long acting carb should be given.
Or a normal carb containing meal, if due
What is an example of a long acting carb?
- Two biscuits
- One slice of bread
- 200-300ml of milk (not soya or alternatives)
When should glucagon be avoided?
- Prolonged fasting
- Adrenal insufficiency
- Chronic hypoglycaemia
- Alcohol-induced hypoglycaemia
- In patient taking Sulfonylurea, give IV glucose instead
What can be given to patients to due the CV risk?
ACE inhibitor, low dose aspirin & lipid regulating drug
What should be done to diabetic patients to prevent nephropathy?
BP should be reduced to lowest level, to prevent decline of glomerular filtration rate and reduce proteinuria
What test must be done for nephropathy?
Test for urinary protein and serum creatinine.
If test is negative, test urine for microalbuminuria (early sign of nephropathy)
What must all patients with nephropathy be given?
Must be given ACEi or ARB, if not contra-indicated; even if BP is normal
