Efficacy and Safety of Continuous Intravenous Versus Usual Subcutaneous Insulin in Acute Ischemic Stroke

It is demonstrated that post-stroke hyperglycaemia is associated with poor outcome. Yet, the efficiency of aggressive insulin serum glucose control is not established. Furthermore the modalities of insulin administration are discussed since US and European guidelines recommend subcutaneous administration, whereas some groups use intravenous administration of insulin. The purpose of this study is to compare the efficacy and the safety of a continuous intravenous insulin protocol versus classical subcutaneous administration of insulin. The study will include carotid territory stroke at the acute stage (\< 6 hours of onset) confirmed by MRI, and randomized in intravenous versus subcutaneous insulin. The percentage of patients in the target range (mean capillary glycaemia within 24 hours \< 7 mmol/l) is the primary outcome. The secondary outcomes include comparison of Modified Rankin Scale at 3 months, rate of hypoglycaemic events and comparison of Infarct Growth as measured on MRI.
