3
Why are we doing this trial? Look at the
literature on glutamine in burn injury
4
Potential Beneficial Effects of Glutamine
GLN pool
5
META ANALYSIS Effect of glutamine on INFECTIONS
6
META ANALYSIS Effect of glutamine on LOS
7
META 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
8
Hypotheses
  • 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

9
Objectives (Pilot Study)
  • Recruitment rate
  • Compliance with experimental procedure
  • 3. Compliance with data collection and transfer
    to the
  • Coordinating Centre (CERU)

Study Overview
Imp Manual p 8
12
Inclusion 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
13
Exclusion 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
14
Imp Manual p 13
To minimize any potential contamination, patients
that have received glutamine supplements for gt24
hrs before randomization, should NOT be included

Study Intervention
Imp Manual p 14
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
18
Imp 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.

EXCEPTION weight lt 54 kgm, upto q 8 hrs. See

  • Prescribed calorie ranges
  • Prescribed protein ranges
  • Vitamin/mineral prescription
  • Optimization of the Delivery of Enteral Nutrition
  • Glycemic control
  • Arginine enriched formulas (gt 6 gms arginine/L)
    i.e.
  • Pivot, Perative
  • Glutamine supplements or formulas containing any
  • additional glutamine

  • 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.
    Inform Research Coordinator of interruptions

SAE Identification
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
56
SAE 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
absence of liver disease. Ischemic bowel in the
absence of massive fluid resuscitation or
increased abdominal pressure/abdominal
compartment syndrome
