Primary Outcome Measures:
  • The change in daily total Sequential Organ Failure Assessment Score (SOFA)each day over 10 days. [ Time Frame: daily until discharge from intensive care unit, death or maximum duration of 10 days. ]
    The change in daily total SOFA score plotted each day over 10 days, where we will compare the regression slope between the two arms of the study.

Secondary Outcome Measures:
  • The change in daily total Sequential Organ failure Assessment Score (SOFA) on the last day of treatment as a measure of severity of organ dysfunction. [ Time Frame: Last day of treatment ]
  • Number of infections that are documented during intensive care unit stay. [ Time Frame: During intensive care unit stay. ]
  • Number of deaths occuring on or before day 60. [ Time Frame: within 60 days. ]
  • Length of stay in intensive care unit. [ Time Frame: At discharge from intensive care unit. ]
  • Length of stay in hospital. [ Time Frame: At hospital discharge. ]
    Length of stay in hospital (if delayed discharge due to placement problems, will record from the date the patient is regarded as fit for discharge by medical staff).

  • Number of days on mechanical ventilation. [ Time Frame: during intensive care unit stay. ]
  • Number of days of antibiotic use during intensive care unit stay. [ Time Frame: during intensive care unit stay. ]
  • Fat free mass and fat percentage as a measure of body composition by Bioelectric Impedance analysis (BIA). [ Time Frame: every 2 days until discharge from the intensive care unit. ]

Detailed Description:

Trauma Patients are characterized by alteration in the immune response, increased exposure to infectious complications, sepsis, and consequently organ failure and death. Glutamine supplementation to parenteral nutrition is one of the nutritional interventions that have been proven to be associated with improved survival rate, decreased infectious morbidity, costs, intensive care unit, and hospital length of stay. However, glutamine supplementation in patients receiving enteral nutrition and its best route are still controversial. A number of trials investigated the beneficial effects of intravenous alanyl-glutamine supplementation in critically ill patients receiving enteral nutrition. However, these trials were: pilot trials, investigated surrogate outcomes, or supplementation was for a short period of time. Therefore, a well designed trial is needed to investigate the effect of intravenous alanyl-glutamine supplementation in critically ill patients with multiple trauma receiving enteral nutrition on major clinical outcomes.

Our hypothesis is that trauma patients receiving standard enteral nutrition supplemented with intravenous alanyl-glutamine will demonstrate improved clinical outcomes compared to patients receiving standard enteral nutrition without supplementation.
