Brief Summary:
The specific aim of this study is to identify the degree of correlation between real time subcutaneous glucose monitoring and intermittent glucose monitoring using capillary glucose samples, arterial blood samples and venous blood samples in critically ill surgical patients. A secondary aim will be to determine the accuracy of real time glucose monitoring.

Study Type : Observational
Actual Enrollment : 24 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Continuous Glucose Monitoring in Critically Ill Surgical Patients
Study Start Date : April 2010
Actual Primary Completion Date : July 2012
Actual Study Completion Date : July 2012

Elective surgical patients
Massive resuscitation patients
surgical patients on pressors

Primary Outcome Measures :
  1. Concordance of continuous glucose monitor with standard capillary and arterial blood glucose [ Time Frame: 9 months ]
    Data from each sensor will be downloaded and blood glucose values obtained using proprietary software from Medtronic. Because the CGMS system records glucose readings every 5 minutes, capillary or arterial glucose samples obtained will be compared with the closest CGMS reading within 2.5 minutes of the time the sample was obtained. This will generate a set of paired glucose levels for analysis.

Secondary Outcome Measures :
  1. Safety of the sensor in terms of infection or bleeding at the insertion site [ Time Frame: 9 months ]
    The monitor insertion site will be observed by the bedside nurse for infectious or bleeding complications
