| Optimize blood glucose control
pre-operatively ( see Assessing metabolic control above ) |

Delay major surgery if possible when HbA1c
>9.0 % or |
 |

 |
fasting glucose >10.0 mmol/l ( >180 mg/dl ), or |
|

 |
post-prandial >13.0 mmol/l ( >230 mg/dl ) |

Screen for complications which may affect surgery risk; alert the
surgical team : |
|

 |
heart or kidney problems |
|

 |
autonomic or peripheral nerve damage |
|

 |
proliferative retinopathy |

Manage blood glucose / insulin : |
|

 |
use IV glucose-insulin-potassium infusion ( GIK ) |
|

 |
start at 0800 h and continue until eating normally |
|

 |
monitor blood glucose before, during, and after ( 1-4 hourly ) surgery |
|
- use a quality-assured method
|
|

 |
aim for blood glucose levels of 6.0-10.0 mmol/l ( 110-180 mg/dl ) |
|

 |
treat hypoglycaemia with glucose and restart GIK at lower insulin dose |
|

 |
never stop intravenous insulin infusions |
|

 |
return to normal timing of insulin injections as soon as practicable |

Encourage supervised self-management while in hospital |
