Q

Hypoglycaemia in unconscious patient

A

Hypoglycaemia which causes unconsciousness is a medical emergency and should typically be treated with 1 mg glucagon IM immediately. However, the BNF state that glucagon is ineffective where liver glycogen is depleted, i.e. prolonged fasting, chronic hypoglycaemia or alcohol-induced hypoglycaemia. Additionally, glucagon may be less effective in patients taking a sulfonylurea (e.g. gliclazide). In these cases, intravenous glucose is required.

150 – 200 mL glucose 10% IV infusion over 15 minutes or

75 – 100 mL glucose 20% IV infusion over 15 minutes should be given.
