Fixed rate Insulin - Actrapid 0.1u/kg/h
Continue giving them their basal insulin regimen too of their long acting to prevent rebound hyperglycaemia.
Swap to dextrose once blood sugar gets below 15
It takes longer to turn off ketogenesis than it does to bring the blood sugar down. So Insulin Must be continued in order to stop ketone production
Resolution when: pH above 7.3; Ketones less than .3
If you can eat and drink then you can go on your basal bolus regime
