Abstract

Introduction: Ventilator-associated events (VAEs) are one of the main sources of concern in critically ill patients due to the high frequency and mortality. We conducted this analysis to compare the effects of open endotracheal suctioning system with closed one on the incidences of VAEs in adult patients receiving mechanical ventilation (MV). Materials and methods: A comprehensive literature search was performed in PubMed, Scopus, Cochrane Library, and hand searching bibliographies of retrieved articles. The search was confined to randomized controlled trials with human adults comparing closed tracheal suction systems (CTSS) vs open tracheal suction systems (OTSS) in prevention of ventilator-associated pneumonia (VAP). Full-text articles were used in order to extract the data. Data extraction was only started after completing the quality assessment. Results: The search resulted in 59 publications. Among them, 10 were identified as eligible for meta-analysis. There was a significant increase in incidence of VAP when using OTSS compared to CTSS, so that OCSS increased the incidence of VAP by 57% (OR 1.57, 95% CI 1.063–2.32, p = 0.02). Discussion: Our results showed that using CTSS can significantly decrease VAP development compared to OTSS. This conclusion does not yet mean the routine use of CTSS as a standard VAP prevention measure for all patients since individual patient's disease and cost are other factors that should be in mind when determining the choice of the suctioning system. High-quality trials with a larger sample size are highly recommended.
