رجل عمره ٥٧ سنة في العناية بعد جراحة قلب، غير مصاب بالسكري، سكره ٢٦٠ و٢٨٠ في قراءتين، وعنده التهاب جرح. ما الإجراء المتوقع؟

A 57-year-old non-diabetic man in ICU after cardiac surgery has glucose 260 and 280 on two readings and a wound infection. What is expected?

1. Oral metformin while he is fasting and intubated
2. Stop all IV fluids in order to lower the glucose
3. An insulin infusion per protocol to control glucose
4. Ignore the glucose because he is not diabetic

Answer: C) An insulin infusion per protocol to control glucose. Stress hyperglycaemia is common after surgery and raises infection risk. It is controlled with a protocol insulin infusion targeting about 140–180 while avoiding hypoglycaemia.
