Study hypothesis
The probiotic bacterium Lactobacillus plantarum 299 reduces growth of pathogenic bacteria in the oral cavity in intubated patients to the same extent as chlorhexidin but is a better ecologic alternative.
Ethics approval
Final ethical approval was obtained from the Human Ethics Committee at the Lund University on the 29th September 2003 (ref: LU 346-03)
Study design
Pilot, prospective, open, randomised controlled study.

Patient information sheet
Condition
Growth of pathogenic bacteria in the oral cavity
Intervention
Ramdomisation is carried out in groups of 10 participants. 20 participants are allocated to each of the two groups.
A The control group will receive the standard oral care of the department (general ICU, Lund University Hospital).
This includes suction of secretions, brushing of teeth cleansing of the oral cavity with swabs soaked with a chlorhexidine solution. This procedure is performed twice a day. In between, suction whenever needed and cleansing with swabs soaked with carbonated bottled water is performed
B The study group will be attended in the same manor but the swabs used for cleansing are soaked with carbonated water directly from freshly opened bottles. As the final part of the procedure oral mucosal surfaces are pencilled with a suspension of the probiotic bacterium Lactobacillus plantarum 299
Cultures from the oropharynx and tracheal secretions are taken at inclusion (day 1) and then on days 2,3,5,7,10,14 and 21 or before extubation if this occurs on a non-culture day

Lactobacillus plantarum and chlorhexidin
Primary outcome measure
Cultures from the oropharynx and tracheal secretions are taken at inclusion (day 1) and then on days 2, 3, 5, 7, 10, 14 and 21 or before extubation if this occurs on a non-culture day (The primary outcomes are validated for the part of the ICU stay during which the patient is intubated). The results of the cultures are used to assess the following:
1. To compare the number of cultures with pathogenic bacteria and fungi from oropharynx and tracheal secretions and the spectra of these microbiologic species
2. Recovery of Lactobacillus plantarum 299 in the treatment group as an indicator of aspiration
Secondary outcome measures
The following will be assessed during the ICU stay during which the patient is intubated:
1. Sequential Organ Failure Assessment (SOFA) score and Lung Injury Severity Score (LISS) will be measured daily during the ICU stay
2. Incidence of ventilator associated pneumonia during the ICU stay
3. Validation of microbiological findings compared to the use of antibiotics, monitored during the ICU stay
4. Infectious parameters (C-Reactive Protein [CRP] and White Blood Cell counts [WBC]), monitored daily during the ICU stay
For the whole ICU period:
5. ICU mortality
For the post-extubation period:
6. In-hospital mortality
Follow-up for survival will be carried out for 6 months from admission to the ICU.
