  • ICU Length of Stay [ Time Frame: Day 28 ] [ Designated as safety issue: No ]
    Measure of the duration of participant stay in the ICU
  • ICU Acquired Infection [ Time Frame: Day 28 ] [ Designated as safety issue: No ]
    We have made some modifications the definitions developed by the International Sepsis Forum Consensus Conference (CCM 2005;33:1538-1548) to operationalize the adjudication of infections in this trial. We grade the certainty of the diagnosis of infection using definitions for 'Definite', 'Probable', and 'Possible' for each category of infection. The categories of infection are: Deep surgical wound infection, Incisional (or superficial) surgical wound infection, Skin and soft-tissue infection (non-surgical) (SSTS), Catheter-related blood stream infections (CRI), Primary blood stream infections (BSI), Lower urinary tract infection, Upper urinary tract infection, Intra abdominal infection, Sinusitis, Lower respiratory tract infection (excluding pneumonia), ICU Acquired Pneumonia and Other.
  • Hospital Length of Stay [ Time Frame: 6 months (from ICU admission) ] [ Designated as safety issue: No ]
    Measure of the duration of the participant's hospital stay
The secondary outcomes are duration of stay in ICU, adjudicated diagnosis of infection, multiple organ dysfunction, duration of mechanical ventilation, hospital length of stay, and health-related quality of life at 3 and 6 months.

Trial of Glutamine and Antioxidant Supplementation in Critically Ill Patients
REducing Deaths Due to OXidative Stress The REDOXS© Study

The purpose of this study is to determine whether providing high dose glutamine and antioxidants to critically ill patients will be associated with improved survival.

Background:

Critically ill patients experience a degree of hyperinflammation, cellular immune dysfunction, and oxidative stress. Supplementation with key nutrients, like glutamine and antioxidants, is most likely to have a favourable effect on these physiological parameters leading to an improvement in clinical outcomes. The results of two separate meta-analyses suggested that glutamine and antioxidants may be associated with improved survival. We have recently completed a dosing study to determine the maximal tolerable dose (MTD) of glutamine dipeptides and antioxidants in critically ill patients with evidence of hypoperfusion. The purpose of this protocol is to evaluate the effect of high dose glutamine and antioxidant supplementation on mortality in a large scale randomized trial.

Study Intervention:

Patients will be randomized to receive glutamine supplementation or antioxidant supplementation (or respective placebo).
