Review Meta AnalysisImpact of closed versus open tracheal suctioning systems for mechanically ventilated adults: a systematic review and meta-analysis.
Whether closed tracheal suctioning systems (CTSS) reduce the incidence of ventilator-associated pneumonia (VAP) compared with open tracheal suctioning systems (OTSS) is inconclusive. We conducted a systematic review and meta-analysis of randomized controlled trials that compared CTSS and OTSS. ⋯ Based on current, albeit limited evidence, it is unlikely that CTSS is inferior to OTSS regarding VAP prevention; however, further trials at low risk of bias are needed to confirm or refute this finding.
