Short-term effect of the application of selective decontamination of the digestive tract on different body site reservoir ICU patients colonized by multi-resistant Acinetobacter baumannii.
The effect of a selective decontamination of the digestive tract (SDD) regimen including polymyxin and tobramycin on several body site reservoirs was compared between a test group and a control group in intensive care unit (ICU) patients with faecal multi-resistant Acinetobacter baumannii colonization. SDD significantly reduced faecal and pharyngeal carriage when compared with the control group at the end of ICU stay (48% versus 91%, P = 0.001, and 38.5% versus 78%, P = 0.01, respectively), but failed to reduce axillary colonization (75% versus 78%, P = 0.6). In addition, the isolation of A. baumannii from new clinical samples was lower in patients with SDD (45.5% versus 81%, P = 0.05). No resistance to polymyxin was observed. We conclude that the digestive tract reservoir of A. baumannii in ICU patients may be decreased by a SDD regimen.
