The Effect of Closed Suction System on the Incidence of Ventilator-associated Pneumonia.

The Effect of Closed Suction System on the Incidence of Ventilator-associated Pneumonia, Respiratory-associated Microbiome and Contamination of Inanimate Surfaces: a Pilot Study.

The investigators are suggesting that closed suction systems may reduce the risk of the ventilator - associated pneumoniae (VAP) and the contamination of the closest unanimated surfaces. In 2011 David et al. have shown that closed suction systems might reduce the incidence of the late VAP. Research team is thinking that preventive bundle with closed suction systems can prevent to onset of the VAP. All enrolled patients is randomizing into two groups: control group - conventional suctioning and research group - suctioning with closed suction system.
