ABSTRACT
Objective:
To investigate the effect of endotracheal tube cuff pressure control on microaspiration and ventilator-associated pneumonia.
Materials and Methods:
This study was created by using the Preferred Reporting Items for Systematic Review and Meta Analysis - Meta Analyzer checklist. Among the electronic databases, Medline/PUBMED, Scopus, Cochrane Library and Google Scholar were scanned for articles published before September 2018 and 1311 studies were reached. After reviewing the eligibility and exclusion criteria, seven experimental/quasi-experimental studies were included. The studies were evaluated with the Turkish Joanna Briggs Institute-Meta Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI) Critical Appraisal Checklist in terms of methodological quality.
Results:
In one study, intermittent control method was used to avoid using any control method and intermittent control method was used despite pilot balloon finger palpation control method in another study. As a result of the methodological quality evaluations of the studies, the lowest score was five and the highest score was nine. It was determined that intermittent and continuous endotracheal tube cuff pressure control method was the most frequently used method in the studies. The incidence of microaspiration was 18% to 80% in three studies, and the incidence of ventilator-associated pneumonia was 2.7% to 67.7% in five studies.
Conclusion:
When the endotracheal tube cuff pressure control method is not used, it is seen that the incidence of microspiration and ventilator-associated pneumonia increases, the methods used are superior to each other, and continuous endotracheal tube cuff pressure control method is recommended to prevent microspiration and ventilator associated pneumonia.
