How to minimise the period of fasting during surgery?
The aim is to minimise the fasting period, ensure normoglycaemia (capillary blood glucose (CBG) 6–10 mmol.l −1) and minimise as far as possible disruption to the patient’s usual routine. Ideally, the patient should be booked first on the operating list to minimise the period of fasting.
What is the guideline for peri-operative adjustment of insulin?
