Algorithm for glucose control in the study

Initial infusion
Blood glucose		Insulin infusion rate	Control interval
(mmol/l)	(mg/dl)		(hours)
7.0–9.9	126–179	1 IU/hour	2
10–11.9	180–214	2 IU/hour	1–2
> 12	> 215	4 IU/hour	1–2
Maintenance infusion
Blood glucose		Insulin infusion rate	Control interval
(mmol/l)	(mg/dl)		(hours)
< 2.5	< 45	10 % glucose 150 ml iv..	0.5
< 3.0	< 54	Stop insulin	1
3.1–3.9	55–71	Reduce insulin dose by half	1
4.0–4.9	72–89	Reduce by 0.5 IU/hour	2
5.0–6.9	90–125	Insulin dose unchanged	2
7.0–9.9	126–179	Increase by 0.5–1 IU/hour	2
10–11.9	180–214	Increase by 1 IU/hour	2
> 12.0	> 215	Increase by 2 IU/hour	2

i.v., intravenously.
