Unformatted text preview: Coma, hypotension, tracheal intubation, antimicrobics, renal failure, metabolic acidosis, leukocytosis or leukopenia all are associated with colonization of the airway by Gram negative bacilli. Age > 70, thoracic or abdominal surgery associated with increased risk.

Decreased gastric acidity associated with increased risk of colonization. In 1960's, outbreaks of Nosocomial Pneumonia were related to contaminated respiratory therapy equipment. With current usage of disposable equipment, this is less of a hazard. Gut decontamination regimens recently fashionable, do not increase survival. For some pathogens such as Pseudomonas or Acinetobacter the risk of death increases 2 fold. Prevention includes prone ventilation, early extubation where feasible....
