ACADEMIC EMERGENCY MEDICINE 2011; 18:436–439 © 2011 by the Society for Academic Emergency Medicine Abstract Objectives: The objective was to assess the feasibility of insulin infusion and subcutaneous insulin administered in the prehospital setting and their relative effect on hyperglycemia, a predictor of unfavorable outcome, in acute stroke patients. Methods: Hyperglycemic patients (plasma glucose >6.0 mmol/L) with stroke symptoms were randomized prior to or during transport to the hospital to receive either 1) a single subcutaneous dose of short‐acting insulin ( n = 11) or 2) a continuous intravenous (IV) insulin infusion ( n = 12) at a rate adjusted by glucose levels measured every 10 minutes and targeted to plasma glucose 4.5–6.0 mmol/L. The changes in plasma glucose concentration were compared with a nonrandomized control group ( n = 38) receiving standard care. Results: The baseline characteristics did not differ between the study groups. Plasma glucose concentration was significantly decreased during the prehospital phase in the IV‐treated group in comparison to the control group (difference between groups –1.9 mmol/L, 95% confidence interval [CI] = –3.5 to –0.27) with no serious adverse events. In contrast, subcutaneous insulin did not achieve significant lowering of plasma glucose (–0.9 mmol/L, 95% CI = –2.4 to 0.6). Conclusions: This small sample suggests that adjusted insulin infusion efficiently lowers blood glucose in the ultra‐acute phase of stroke and is feasible in the prehospital setting.
