Viewpoint: survival benefit by selective decontamination of the digestive tract (SDD).

Morbidity and mortality due to infection acquired either before or after admission to the intensive care unit is still a major problem. A limited range of potentially pathogenic microorganisms (PPM) are involved, and infection with these PPM usually follows a predictable pattern. Selective decontamination of the digestive tract (SDD) should be investigated further in patients with primarily curable diseases who are not infected on admission to intensive care but become infected there.
