Brief Summary

Ventilator-associated pneumonia (VAP), is a type of pneumonia that develops more than 48 hours after endotracheal intubation, is common in intensive care units (ICUs). It is estimated to be responsible for 27% to 47% of ICU-acquired infections. The pathogenesis of VAP is complex but typically involves colonization of the aerodigestive tract with pathogenic bacteria, the formation of biofilms, and microaspiration of contaminated secretions. Preventing carriage of potentially pathogenic micro-organisms from the aerodigestive tract is an infection control strategy used to reduce the occurrence of VAP. One novel intervention is the administration of prophylactic probiotics which restore non-pathogenic flora that compete with pathogens, modulate local and systemic immunity, and decrease intestinal permeability and thus can be beneficial in preventing nosocomial infections in critically ill patients. The role of the probiotics in preventing VAP in mechanically ventilated patients is inconclusive. Some evidence indicates that probiotics may reduce the incidence of VAP by inhibiting pathogen adhesion, improving gut mucosal barrier function, reducing bacterial translocation and up-regulating the immune system. Furthermore, guidelines remain inconclusive regarding the role of commensal oropharyngeal flora (COF) as a causative agent in VAP, mainly due to a scarcity of studies in this research field. However, there is evidence that COF may cause pulmonary infection, mostly in immunocompromised patients.

Outcome Measures

Primary Outcomes (1)

  • Probiotics for VAP prophylaxis

    To determine the efficacy of probiotic administration for the prophylaxis of VAP in a multi trauma population admitted in the ICU This outcome will be assessed by the difference of number of cases (n) and percentage of change (%) in VAP development between probiotics and control groups Ventilator associated pneumonia (VAP) will be defined as pneumonia developing more than 48 h after endotracheal intubation and initiation of mechanical ventilation. The diagnostic criteria for VAP will be the following: * SOFA score elevation of at least 1 point * New or progressive radiographic consolidation or infiltrate. In addition, at least 2 of the following: * Temperature \> 38 °C * Leukocytosis (white blood cell count ≥ 12,000 cells/ mm3) or leukopenia (white blood cell count \< 4,000 cells/mm3) * Presence of purulent secretions * BAL \> 104 colony forming units (CFU)/ml)

    30 days

Secondary Outcomes (2)

  • Probiotics for indections control

    30 days

  • Probiotics for bacteremia, sepsis or septic shock reduction

    30 days

Other Outcomes (1)

  • Impact of Probiotics use on parameters related to hospitalization and mortality

    30 days
