Abstract
Objective: To perform a systematic appraisal to compare the effectiveness of the use of endotracheal tube with continuous and intermittent suction drainage system on the rate of VAP, length of stay in ICU, and mortality rate.
Methods: PubMed, CINAHL, MIDLINE, and Cochrane databases were used to find relevant articles. Peer-reviewed, full-text, and original article that were written in English-language and published between 2000 to May 2019 included in the study. The articles must be randomized control trial and used either continuous and/or intermittent suction drainage system as an intervention and ventilator-associated pneumonia rate, length of stay in intensive care unit, and/or mortality rate as an outcome. Data were analyzed using secondary analysis.
Findings: 10 primary studies met the inclusion criteria of this study. These studies were summarized and criticized. Out of 10 studies, 7 studies supported that the two types of subglottic suction drainage can be used to reduce ventilator associated pneumonia. 7 studies from the 10 also examined the effect of intensive care unit length of stay and mortality rate and only 3 studies found reduction on the length of stay, whereas reduction on the mortality rate was found only on 2 studies.
Conclusion: This systematic appraisal concluded that both intermittent and continuous subglottic suction drainage appears to be an effective intervention on reducing the rate of ventilator associated pneumonia, but not necessarily the length of stay in the intensive care unit and mortality rate.
