Maintenance of the gut environment is a key factor in determining outcome in the care of critically ill and postoperative patients. It is especially important to maintain both gastrointestinal secretions, full o anti-infectious and anti-inflammatory compounds, and the gut flora. Prebiotics, usually polysaccharides, exhibit strong bio-activity and the ingestion of prebiotics has been shown to reduce the rate of infection and restore health in sick and postoperative patients. Probiotics may have at least five functions, all of great importance to the sick patients: the reduction or elimination of potentially pathogenic micro-organism of various kinds; the reduction or elimination of various toxins, mutagens, carcinogens, etc.; modulation of the innate and adaptive immune defence mechanisms; the promotion of apoptosis; and the release of numerous nutrient, antioxidant, growth, coagulation and other factors necessary for recovery. A combination of pre and probiotics is referred to as "synbiotics". Our experience of synbotic treatment in critically ill patients is limited, but cutting-edge results from studies of severe acute pancreatitis, chronic hepatitis and liver transplantation offer great hope for the future. This is especially importante as pharmaceutical treatment, including the use of antibiotics, has largely failed, and the medical world is in much need of new treatment paradigms.
