Original Title:
Σύγκριση μεταξύ ανοιχτού και κλειστού συστήματος αναρρόφησης αναφορικά με την πρόληψη των λοιμώξεων του αναπνευστικού σε μηχανικά αεριζόμενους ασθενείς
Translated title:
Comparison between open and closed suction system in relation to preventing respiratory infections in mechanically ventilated patients
Summary:
Ventilator-associated respiratory infections are the most common nosocomial infections in intensive care units (ICUs) and can lead to high mortality rates. Endotracheal suctioning is commonly performed in mechanically ventilated patients to remove secretions and has been associated with ventilator-associated respiratory infections.
Purpose: The purpose was to compare open and closed endotracheal suction systems regarding the incidence of respiratory infections in mechanically ventilated patients. In addition, to study the effects of the two suction systems on the microbial colonization of the airways, the length of ICU stay of the patients, the mortality rates and also the cost of their use.
Methodology: A systematic review was performed. The literature was searched in Medline (Pubmed), Google Scholar and Scopus (Elsevier) databases. The systematic literature review was based on the PRISMA proposal guidelines. included 9 randomized trials written in the English language were included, that were published in the last decade, and involved mechanically ventilated patients undergoing open and closed endotracheal suctioning. The keywords used were in the English language and included the terms "comparison of closed and open endotracheal suctioning", "VAP" and "adults".
Results: 9 studies were selected in the present systematic review. Five of the nine articles concluded that the closed endotracheal suction system was superior to the open one in terms of the prevention of Ventilator Associated Pneumonia, while four of the nine articles found no statistically significant difference between the two types of suction systems. In addition, the type of suction system was found to affect microbial colonization of the airways, with the closed system leading to faster airway colonization by multidrug-resistant organisms. The type of suction system did not influence length of ICU stay, nor the mortality rates of the patients. Finally, closed endotracheal suctioning was found to be associated with higher costs of use.
Conclusions: The use of the closed endotracheal suction system shows a slight superiority compared to the open one in preventing the occurrence of VAP. A necessary condition for this is the correct raining of health professionals and the observance of stricter aseptic protocols.
