PREVENTION OF VENTILATOR ASSOCIATED PNEUMONIA: Proposed Methods of VAP Prevention: A large list of methods for preventing VAP can be found in the recent literature. Most of them proved to be ineffective: use of sucralfate, oscillating beds, digestive decontamination, Myney Hayeshuah Medical Center, Bnai Brak & Ben Gurion frequent change of ventilator circuits or aerosolized anti- University of the Negev, Beer Sheva, Israel biotics. In the last couple of years some clinical studies used what is called ‘‘a VAP bundle policy’’ which would Introduction: Hospital acquired pneumonia remains an include : head of bed elevation, interruption of sedation important cause of morbidity and mortality in our on a daily basis, oral suction before each change of posi- intensive care units (ICU), despite advances in antimi- tion, patient early mobilization.

This statement, change in VAP incidence when using ‘‘VAP bundle’’ published some years ago, still has a strong support in the reality of our days.

This is why it becomes evident that a search for a reliable Pathophysiology: The main causative factor of VAP is method of VAP prevention is perfectly justified and aspiration of supraglottic secretions into the lung parenchyma. The explanation for VAP development is based on the simple fact that tracheal intubation and mechanical ventilation impair the natural defense mechanisms, which are supposed to prevent aspiration of the supravocal cords secretions: the cough reflex and mucocilliary clearance. Beside, injury of tracheal epi- thelial cells and decrease of bacterial adherence to tra- cheal epithelial cells must be added to the list of impaired defense factors affected by prolonged tracheal intubation and mechanical ventilation. Diagnosis: The data from literature are controversial. Some authors would use a simple list of diagnostic criteria: leukocytosis, fever, purulent sputum, radiological infil- trates and absence of any other evident infection focus. But some others would add a positive culture either from a tracheal aspirate or even from bronchoalveolar lavage (BAL). This is the explanation on the fact that some ICUs report a much lower incidence of VAP than that men- tioned in most of the pertinent papers. In the last years, there is an evident trend to artificially lower the incidence of VAP in the USA, since the Medicare payment does not cover ‘‘preventable’’ complications! But the main problem of VAP is that as per today, there is no proved method of prevention!
