Primary Objective:

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.

Secondary Objectives:

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 ICU stay.

Dietary Supplement: Jevity - Control Diet
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator)
Primary Purpose: Treatment
Official Title: Enteral Nutrition and Glycemic Variability NICU Study

Further study details as provided by Eastern Virginia Medical School:

Primary Outcome Measures:
  • Glycemic Variability [ Time Frame: Entire ICU stay. Up to 14 days in the ICU (average about 7 days) ]
    The patients blood glucose levels will be monitored with a continuous blood glucose monitor which records the calibrated blood glucose level every minute. The mean blood glucose over the patients entire ICU stay (up to 14 days) as well as the mathematical variation (fluctuation) in blood glucose levels will be calculated. The degree of glycemic variation will be assessed by a number of mathematical formula, including mean amplitude of glycemic excursions (MAGE). These parameters will be compared between the control and intervention groups.

Secondary Outcome Measures:
  • Quadriceps Muscle Volume [ Time Frame: First versus last measurment in ICU. Up to 14 days (average 7 days) ]
    The quadriceps muscle volume will be estimated by 2-dimensional ultrasound imaging at enrollment and at the end of the study period (when the patient is being transferred from the ICU or no longer receiving tube feeds). The change in muscle mass during the ICU stay will be compared between the control and intervention groups.
