Summary: | Background: Ventilator-Associated Pneumonia (VAP) is an undesired side effect of mechanical ventilation in intensive care units (ICUs).
Aim: We evaluated whether endotracheal tubes with subglottic secretion drainage (SSD) would reduce the incidence of VAP among patients undergoing mechanical ventilation in an ICU.
Methods: The analysis of medical records of patients undergoing mechanical ventilation exceeding 48 h who were hospitalised in ICUs between 2007 and 2014 led to separating two groups of patients: those in whom no subglottic drainage was applied (NSSD) (records dating from 2007-2010) and those whose treatment involved endotracheal tubes with subglottic secretion drainage (SSD) (records dating from 2011-2014).
Results: Analysis of 1807 patients hospitalised in ICUs (804 NSSD patients and 1003 SSD patients). A difference was found in the frequency of VAP incidence between the groups (P<0.001). In the NSSD group as many as 84 cases were reported (incidence: 10.7%), and in the SSD group - 43 cases (incidence: 5.2%). The odds ratio (OR) and relative risk (RR) was 2.5. The probability of VAP was significantly higher in the NSSD group. The risk factors of VAP incidence (P<0.001) included the correlation between reintubation (R=0.271), tracheostomy (R=0.309) and bronchoscopy (R=0.316).
Conclusion: Use of endotracheal tubes with subglottic secretion drainage in patients in the ICU on mechanical ventilation significantly reduced the incidence of VAP. |
