Abstract

This study was undertaken to examine whether the incidence of bacterial colonization and ventilator- associated pneumonia (VAP) is associated with the type of endotracheal suctioning system in mechanically ventilated adults. Patients were divided into two groups: one for closed endotracheal suctioning system (CES) and the other for open endotracheal suctioning system (OES) protocol. Incidence of colonization, VAP with the two different suctioning protocols were compared. The results are summarized as follows: The incidence of colonization was not significantly different between both groups (x2=0.530, p=0.467). However the number of pathogens in CES was lower than in OES (t=-2.418, p=0.020). The occurrence of VAP in CES was lower than in the OES (x2=4.629, p=0.031). These results suggest that, the closed endotracheal suctioning protocol be applied more widely in the intensive care unit.
