Objective: Ventilator associated pneumonia (VAP) has been shown to be associated with significant morbidity and mortality( Chastre and Fagon, 2002; klompas, 2007) among mechanically venti- lated patients in the intensive care unit (ICU), with the incidence ranging from 9% to 27% ; crude mortality ranges from 25% to 50%.1-3 A meta-analysis of published studies was undertaken to combine information regarding the effect of subglottic secretion drainage (SSD) on the incidence of ventilated associated pneumonia in adult ICU patients. Methods: Reports of studies on SSD were identified by searching the PUBMED, EMBASE, and COCHRANCE LIBRARY databases (December 30, 2010). Randomized trials of SSD compared to usual care in adult mechanically ventilated ICU patients were included in this meta-analysis. Results: Ten RCTs with 2,314 patients were identified. SSD significantly reduced the incidence of VAP [ relative risk (RR) =0.52, 95% confidence interval (C/): 0.42-0.64, P〈0.000 01]. When SSD was compared with the control groups, the overall RR for ICU mortality was 1.00 (95% CI, 0.84-1.19) and for hospital mortality was 0.95 (95% CI, 0. 80-1.13). Overall, the subglottic drainage effect on the days of mechanical ventilation was -1.52 days (95% CI, -2.94 to -0.11) and on the ICU length of stay (LOS) was -0.81days (95% CI, -2.33 to -0.7). Conclusions: In this meta-analysis, when an endotracheal tube (ETT) with SSD was compared with an ETT without SSD, there was a highly significant reduction in the VAP rate of approxi- mately 50%. Time on mechanical ventilation (MV) and the ICU LOS may be reduced, but no reduction in ICU or hospital mortality has been observed in published trials, 展开更多

The aim of this prospective study was to evaluate the incidence, etiologic agents and mortality rate of ventilator-associated pneumonia (VAP). In a six-month period, cases who were 18 years or older, dependent on mechanical ventilator for more than 3 days and without pulmonary infection on first admission were included in this study. In all cases, body temperature recordings, blood and urine culture, microbiological analyses of endotracheal aspirates, and chest X-rays were obtained and used to identify VAP. Apache II scores on admission, duration of mechanical ventilation, length of intensive care unit (ICU) stay and mortality were recorded. This study included 45 cases and 22 developed VAP (48%). The incidence of VAP was 25.34 per 1000 ventilator days. Univariate analyses showed that duration of mechanical ventilation, length of ICU stay, coma and tracheotomy were associated with the development of VAP. The mortality rate of cases with VAP (72.7%) was significantly higher than cases without VAP (39.1%). The most frequent microorganisms were Acinetobacter spp., Pseudomonas aeruginosa and Klebsiella pneumoniae. In our study, VAP was a very common and important complication of mechanical ventilation and mortality was very high. To reduce mortality, minimize morbidity, shorten the length of stay, and reduce costs, defined risk factors for VAP should be recognized and an effective infection control program for the prevention of VAP should be implemented. Surveillance results should be evaluated regularly and necessary precautions should be taken. 展开更多

However, it was poorly adhered in clinical practice. This observational study aimed to investigate the factors impeding this simple practice at the bedside. Methods This prospective study was conducted in 33 Chinese academic hospital intensive care units (ICUs). HOB angle was measured four times daily at 5-7 hour intervals. The predefined HOB elevation goal was an angle ≥30°. Results The overall rate of achieving the HOB goal was 27.8% of the 8647 measurements in 314 patients during 2842 ventilation days. The HOB goal of ≥3 times/d was consistently achieved only in 15.9% of the cases. Almost 60% of patients had at least one 24 hours period during which the HOB goal was never documented. This low rate of protocol compliance was not associated with acute physiology and chronic health evaluation (APACHE) II score or dependence on vasopressors. In a survey, "nurse workload" was identified as the most important factor for non-compliance with the HOB goal. In addition, the rates of compliance were significantly different (P 〈0.001) between physicians self-reporting that they either did or did not know the Institutes of Healthcare Improvement (IHI) ventilator bundle. Conclusions Low adherence to a HOB angle of ≥30° was found in this nationwide survey. Nursing workload and lack of knowledge on VAP prevention were important barriers to changin.q this practice. 展开更多
