BACKGROUND: Reduction of potential pathogens by selective intestinal decontamination has been proposed to improve intensive care. Despite large scientific interest in this method, little is known about its benefit in homogeneous trauma populations. METHODS: In a prospective, controlled study, we enrolled non-infected trauma patients (age over 18 years, mechanical ventilation > or = 48 hours, intensive care for more than 3 days) who primarily were admitted to our university medical center. We randomized patients to be treated with two different topical regimens (polymyxin, tobramycin, and amphotericin (PTA) or polymyxin, ciprofloxin, amphotericin (PCA)) or the carrier only (placebo), administered four times daily both to the oropharynx and to the gastrointestinal tract. All patients received intravenous ciprofloxacin (200 mg, bd) for 4 days. FINDINGS: Of 357 enrolled patients, 310 (age 38.0 +/- 16.5 years, Injury Severity Score 35.2 +/- 12.7) met all inclusion criteria. Selective decontamination successfully reduced intestinal bacterial colonization. However, we did not identify significant differences between groups regarding pneumonia (PTA 47.5%, PCA 39.0%, placebo 45.3%), sepsis (PTA 47.5%, PCA 37.8%, placebo 42.6%), multiple organ failure (PTA 56.3%; PCA 52.4%, placebo 58.1%), and death (PTA 11.3%, PCA 12.2%, placebo 10.8%). Total costs per patient were highest with the PTA regimen. CONCLUSIONS: We found no benefit of selective decontamination in trauma patients. Apparently, bacterial overgrowth in the intestinal tract is not the sole link between trauma, sepsis, and organ failure.
