Surgery in Diabetic Patients

If first on morning list: No morning insulin. Check blood glucose pre-op: 6-13 mmol/l - proceed with operation. > 13 mmol/l- give insulin and glucose as for major surgery. <6 mmol/l- set up 5% glucose drip. Monitor blood glucose every 2 h as well as immediately pre- and post-op. By lunch-time patient should be able to eat and drink, so give half morning insulin as fast-acting (soluble) insulin with lunch. Give normal evening insulin.
