Ventilator-associated pneumonia in critically ill infectious diseases patients

A prospective surveillance of incidence of VAP has been condicted in patients hospitalised in ICU of University Hospital for Infectious Diseases since 1990. Diagnostic criteria of pneumonia were new onset of fever, new or progressing infiltrate on the x-ray of the chest persisting>24 hours, purulent tracheal secretion, leucocytosis (not necessary), physical findings suggesting lung infiltration (not necessary), isolation of pathogenic bacteria from tracheal secretion (not necessary) and positive blood cultures (not necessary). At the end of 1995 new prophylactic measures were introduced into patients’ care: The measures consisted of printing prophylactic care protocols, abandonig use of humidifiers, introduction of use of closed systems for tracheal aspiration and use of bacteriologic and moisture filters as well as continuous nasogastric feeding from 6am to 12pm using enteral pump. After the introduction of these measures a significant decrease of incidence of VAP occurred. From 1990 to 1995 there were 12.9 to 28.9 episodes of VAP per 1000 days of MV. From 1996 number of episodes is steeadily decreasing from 9.7 in 1996 to 4.5 in 1999.
