Anaesthesia · Critical care, resuscitation, and emergency principles: curriculum recognition
Sample itemWhich blood glucose range is generally targeted in critically ill adults, with an insulin infusion started once the glucose exceeds about 180 mg/dL?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
B. 140 to 180 mg/dL
A moderate target of 140 to 180 mg/dL is recommended. Tight control to 80 to 110 mg/dL increased hypoglycaemia and mortality in the large NICE-SUGAR trial, whereas allowing higher values risks hyperglycaemic complications.
Option by option
A. 80 to 110 mg/dL
Tight control caused more hypoglycaemia and no benefit.
B. 140 to 180 mg/dL (correct)
Correct. A moderate target avoids both marked hyperglycaemia and hypoglycaemia.
C. 60 to 80 mg/dL
These values lie in the hypoglycaemic range.
D. 200 to 250 mg/dL
This range permits harmful sustained hyperglycaemia.
