CALVO A, Mario et al. Update. Consensus on Ventilator Associated Pneumonia: Second Part: Prophylaxis. Rev. chil. infectol. [online]. 2011, vol.28, n.4, pp.316-332. ISSN 0716-1018.

Ventilator associated pneumonia is a life threatening disease, in spite of advances in its treatment, consequently the development of prevention strategies is a key factor in improving the morbidity and mortality in intensive care units (ICU). The new developments in this field in the last years led to the need to update the recommendations done in 2001. Then, a new search and analysis of scientific literature was performed. The obtained data support different strategies highlighting: semi-recumbent position at 45° of patients; incorporation of routinely oral hygiene procedures with chlorhexidine; preference of orotracheal intubation; performing subglotic aspiration; use of standard hand hygiene techniques; not routine change of ventilator circuits; and defining bundles to organize the work at ICU. Some strategies were recommended for being of similar efficacy to others but cost-effective as: use of heat and moisture humidificators; and changing humidificators every 5 to 7 days. The use of open or closed endotracheal suctioning system does not affect the incidence of pneumonia. Some recommendations were not incorporated because of lack of evidence supporting effectiveness, controversial data or doubtful application to our country as selective digestive decontamination.
