ABSTRACT

Objective. To study the effect of ventilator circuit changes every 72 hours and 24 hours on the incidence of ventilator-associated pneumonia (VAP).
Design. Clinical, prospective, aleatorized study.
Setting. An ICU of a tertiary care hospital of México City.
Patients. Eighty four patients assisted with mechanical ventilation (AMV).
Interventions. Ventilator circuit were changed every 72 hours (group A, 42 patients) and every 48 hours (group B, 42 patients). Bronchial cultures and chest radiographs were performed during the 1st AMV day and thereafter every 72 hours until extubation. Age, gender, diagnosis, AMV indication, use of aerosol therapy, H2 blockers, antiacids and antibiotics, and APACHE II Score and Multiple Organ Dysfunction Scale (MODS) were registered.
Results. VAP was present in six patients of group A and in three of group B (p = 0.480) and the germs isolated were: P. aeruginosa, C. albicans, K. pneumoniae and Enterobacter sp. An statistically differences about age, AMV days, ICU stay, APACHE II Score, MODS and mortality did not find between the two groups.
Conclusion. Ventilator circuit changes are not associated with the developing of VAP in our ICU.
