Intensive insulin therapy
- tight control of blood sugar in the range of 4.4-6.1
mmol/l associated with
improved outcome (42% decrease in ICU mortality). Not clear whether this beneficial effect is due to tight
control per se or is the effect of insulin as the patients in the
study received a continuous infusion of 10% glucose. There is evidence to
suggest that the beneficial effect results from non-glucose related effects
of insulin:
- anti-inflammatory effect
- prevention of immune paralysis
Ischaemic heart disease
- some evidence to suggest that glucose-insulin-potassium (GIK) infusions
may improve outcome following acute myocardial infarction and following
coronary artery bypass surgery. (Also many of the patients in the study
showing tight glucose control improves outcome were post-cardiac sur
- keep plasma glucose <6 mmol/l. Continue for 24-48h post reperfusion
