Study information
Scientific title
REducing Deaths due to OXidative Stress: a randomised trial of glutamine and anti-oxidant supplementation in critically ill patients
Acronym
REDOXS©
Study hypothesis
Primary hypothesis:
Glutamine and antioxidant supplementation improves the survival of critically ill patients or reduces 28 day mortality.
Secondary hypothesis:
Glutamine and antioxidant supplementation will have a favourable effect on duration of mechanical ventilation, stay in Intensive Care Unit (ICU) and hospital, development of infectious complications, multiple organ dysfunction, antibiotic use, mitochondrial function and quality of life.
Ethics approval
Research Ethics Board of Queen's University Health Sciences and Affilated Teaching Hospitals (Canada), 22/03/2006
Study design
Multicentre non-pharmaceutical randomised factorial 2x2 design, placebo trial with study participants, investigator, caregiver, study nurses gathering data, outcome assessor, and data analyst blinded.

Eligibility
Participant inclusion criteria
1. Mechanically ventilated adult patients (more than or equal to 18 years old, either sex) admitted to ICU
2. Two or more of the following organ failures related to their acute illness:
2.1. A Partial Pressure of Oxygen in Arterial Blood (PaO2)/Fraction of Inspired Oxygen (FiO2) ratio of less than or equal to 300
2.2. Clinical evidence of hypoperfusion defined as the need for vasopressor agents (norepinephrine, epinephrine, vasopressin, more than or equal to 5 µg/kg/min of dopamine, or more than or equal to 50 µg/min phenylephrine) for greater than or equal to two hours
2.3. In patients without known renal disease, renal dysfunction defined as a serum creatinine more than or equal to 171 µmol/L or a urine output of less than 500 ml/last 24 hours (or 80 ml/last four hours if a 24 hour period of observation not available). In patients with acute on chronic renal failure (pre-dialysis), an absolute increase of more than or equal to 80 µmol/L from baseline or pre-admission creatinine or a urine output of less than 500 ml/last 24 hours (or 80 ml/last four hours) will be required
2.4. A platelet count of less than 50 x 10^9/L
