3Why are we doing this trial? Look at the
literature on glutamine in burn injury
4Potential Beneficial Effects of Glutamine
GLN pool
5META ANALYSIS Effect of glutamine on INFECTIONS
6META ANALYSIS Effect of glutamine on LOS
7META ANALYSIS Effect of glutamine on mortality
The effects of glutamine on infectious morbidity
and mortality in burn patients have not been
determined in a large study
8Hypotheses
- In adult subjects with severe thermal burn
injuries enteral - glutamine
- 1) decreases in-hospital mortality
- 2) decreases infectious morbidity and shortens
length of care in - adult subjects with severe thermal burn
injuries - 3) decreases the cost of care of adult subjects
with severe - thermal burn injuries
9Objectives (Pilot Study)
- Recruitment rate
- Compliance with experimental procedure
- 3. Compliance with data collection and transfer
to the - Coordinating Centre (CERU)

11 Study Overview
Imp Manual p 8
12Inclusion Criteria
Imp Manual p 12 Study Tools/CRF
Inclusion criteria all criteria 1, 2 and 3 must
be met for patient to be eligible
Assessed by the burn surgeon (clinical judgment,
Lund Browder) soon before randomization
13Exclusion Criteria
Imp Manual p 13 Tools/CRFs
Exclusion criteria patient is ineligible if any
one of the following is met
product to be given soon after injury
urine tests as standard of care
NPO not an exclusion
96 hrs if resuscitation before ICU
admission (per Site Investigator) Consent 24 hrs
from admit
14Imp Manual p 13
To minimize any potential contamination, patients
that have received glutamine supplements for gt24
hrs before randomization, should NOT be included

OR
MALTRIN Maltodextrin
Enteral glutamine (0.5 gm/kg/day) or maltodextrin
will be given through the feeding tube, qx4h
until 7 days post last successful graft
18Imp Manual p 15
- Intervention to start ASAP
- within 2 hrs of randomization
- within 48 hrs-50 hrs of admission to ICU
- To be administered by RN as a bolus infusion via
- NG/feeding tube q 4 hrs
- If po, give TID or QID (mixed in apple juice,
oatmeal, pudding, etc) - NOT to be mixed with orange juice, grapefruit
juice or lemonade - Product is to given regardless of whether the
attending MD wants to start enteral nutrition
supplement vs. nutrition
19 Delivery of Supplement
Imp Manual p 15
- Powder is to be mixed in 50 mls water q 4 hrs by
RN (sterile/tap as per standard practice for
enteral nutrition) and given as a bolus. Followed
by flushes - Avoid any interruptions to the daily dose. Do not
hold for surgery/procedures. - Missed doses can be made up by doubling the dose
at the next scheduled interval.

- Determine packets per interval (see Dosing
Chart) - At each dose, open the packets needed and pour
into a sterile specimen cup - Using a 60 ml syringe, add 50 mls of sterile
water/tap water for each 5 gm package (as per
standard practice for EN) mix well. Transfer the
mixture into a 60 cc syringe - Infuse as a bolus q 4 hrs unless po, then mix in
liquid and give TID with meals/snacks - Record all dosages given on the Medication
Administration Record as RE-ENERGIZE supplement
as packets per interval. - To keep all the unused packages in a bag with the
patients ID on it and give to Research
Coordinator - Make up for missed doses by giving dose in
addition to next scheduled dose at next interval.

Imp Manual p 41-51
- A serious adverse event is any untoward medical
occurrence that at any dose, - Results in death
- Is life threatening
- Requires or prolongs in-patient hospitalization
- Results in persistent or significant
disability/incapacity - May require medical or surgical intervention to
prevent one of the other - outcomes to defining serious
- Is a congenital anomaly/birth defect
An unexpected adverse event is that event that is
NOT expected due to the progression of the
underlying disease or co-morbid illnesses.
Adverse Event must be serious and unexpected to
be reported
56SAE Reporting Events must be Serious Adverse
Events and unexpected
A serious adverse event
An unexpected adverse event
Examples of unexpected events Cardiac arrest in
a pt without a history of cardiac disease. New
seizure in the absence previous seizure
disorder. Worsening encephalopathy in the
