Brief Summary:
This study plans to learn more about the impact of enteral nutrition on bacteria in critically ill trauma patients with brain injury. Specifically, it seeks to understand the effect that a prebiotic containing enteral feeding formula (Nutraflora scFOS in Vital AF) has on the gut, oral, and skin bacteria. A prebiotic is a special form of dietary fiber that acts as a fertilizer for good bacteria. The prebiotic Nutraflora scFOS has been cleared by the U.S. Food and Drug Administration and is not considered investigational as used in this study. Enteral feeding is a way to give nutrition to critically ill people who are unable to eat.

Primary Outcome Measures :
  1. Changes in microbiome [ Time Frame: Baseline (within 48 hours of ICU admission), up to 10 days ]
    Stool samples

  2. Overall microbiome composition sampling gut [ Time Frame: Baseline (within 48 hours of ICU admission), up to 10 days ]
    Stool samples

  3. Change in microbiome longitudinally [ Time Frame: Baseline at Day 2, 4, 6, 8 and 10 ]
    Tongue swab microbiome longitudinally

  4. Changes in the microbiome on delivery of initial clinical outcomes in trauma patients [ Time Frame: Baseline (within 48 hours of ICU admission), up to 10 days ]
    Stool samples


Secondary Outcome Measures :
  1. Record length of mechanical ventilation [ Time Frame: Up to 60 days ]
  2. Length of ICU [ Time Frame: Up to 60 days ]
  3. Length of hospital stay [ Time Frame: Up to 60 days ]
  4. Mortality [ Time Frame: Up to 60 days ]

Criteria

Inclusion Criteria:

  1. Adult major neurological injury trauma patients between 18-70 years of age who have been admitted directly to trauma ICU following major trauma
  2. Expected length of mechanical ventilation > 48 hours (as judged by admitting clinician)
  3. Expected length of ICU stay > 3 days (as judged by admitting clinician)
  4. Expected to survive > 48 hours (as judged by admitting clinician)
  5. Requiring enteral nutrition at any time in Intensive Care Unit (ICU) stay
  6. Chronic illnesses must be under control (as determined by the Principal Investigator).

Exclusion Criteria:

  3. Received antibiotics within the previous month
  4. On steroids or immunosuppressants at time of admission
  5. All transplant patients
  6. Chronic inflammatory disease that requires steroids or other biologic therapy intervention (e.g.: RA, IBD that requires steroids or Humira)
  7. Undergoing active chemotherapy/radiation treatment
  8. Renal failure requiring dialysis
  9. Liver cirrhosis class C
