To determine the effects of a diabetes specific enteral formula compared to a standard
formula supplemented with protein (isocaloric and isonitrogenous) on the mean blood glucose
and glycemic variability in a homogenous group of critically ill patients in a neurological
ICU. Blood glucose will be recorded every minute using a continuous blood glucose monitor.
The primary end points will be the difference between the mean blood glucose levels and the
glucose variability between the control and intervention groups for the time period that the
patient is in the ICU and receiving tube feeds and for up to a maximum of 14 days.
To determine the effects of the diabetes specific versus standard tube feeds on the change in
muscle thickness and volume measured by 2-dimensional ultrasound imaging during the patients
