VAP was diagnosed according to clinical and microbiological criteria. RESULTS: VAP occurred in 18(7.4%) patients, with an incidence of 10 per 1000 d of mechanical ventilation(MV). Isolated bacterial etiologic agents were mainly Enterobacteriaceae(79%). Univariate logistic analysis showed that model for end-stage liver disease(MELD) score, pre-operative hospitalization, treatment with terlipressin, Child-Turcotte-Pugh score, days of MV and red cell transfusion were risk factors for VAP. Multivariateanalysis, considering significant risk factors in univariate analysis, demonstrated that pneumonia was strongly associated with terlipressin usage, pre-operative hospitalization, days of MV and red cell transfusion. Mortality rate was 22% in the VAP group vs 4% in the group without VAP. CONCLUSION: Our data suggest that VAP is an important cause of nosocomial infection during postoperative period in OLT patients. MELD score was a significant risk factor in univariate analysis. Multiple transfusions, treatment with terlipressin, preoperative hospitalization rather than called to the hospital while at home and days of MV constitute important risk factors for VAP development.展开更多

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

Studies have consistently shown that a delay in diagnosis and treatment increases the mortality risk. The aim of this work was to clarify the role of the serum procalcitonin (PCT) in the diagnosis and the prognosis of ventilator associated pneumonia. Methods: Forty two VAP patients, 20 non VAP-ICU (on mechanical ventilation) admitted patients and 20 healthy control subjects of similar age and sex were included in the study. PCT levels in serum samples were measured in all subjects. Results: There was a highly statistically significant difference (p value 0.001) between VAP patients on one side and non VAP-ICU patients and healthy control subjects on the other side regarding the mean values of PCT. Also, the mean values of PCT were statistically significantly higher (p 0.001) among died VAP group than the survivor VAP group. There was a statistically positive correlation (p = 0.449), CRIP (R = 0.403) and SOFA (R = 0.437)) and initial PCT serum levels. Conclusions: This study found that the increased PCT serum level is an important diagnostic tool for VAP and the PCT serum levels can predict the outcome of VAP patients. We recommend other larger studies to augment our findings.展开更多

We studied 122 patients with Pseudomonas aeruginosa VAP. A follow-up respiratory sample was collected on days three or five ( “day-three” and “day-five” group ) and treatment was modified 48h later. Molecular typing identified super-infections or persistence. For serial data another respiratory sample was collected, on day three from the “day-five” group and on day five from the “day-three” group. Sixty patients, in the “day- three” group compared to 62 in the “day-five” group, had reduced fourteen-day mortality ( 18.3% and 38.7%;p=0.01 ) and fewer days in intensive care unit (17.2 ± 4.3 compared to 27.3 ± 4.7, p6, improved fourteen-day mortality and shorter duration of stay in health-care facilities were observed with earlier follow-up.展开更多

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

We also examined pathogens, rate of progression from VAT to VAP, and impact of antibiotic therapy for VAT. Data analysis included 234 patients, 100 patients (43%) had at least moderate (+++) bacterial growth in their semi-quantitative endotracheal aspirate (SQ-ETA) cultures. VAT and VAP were each diagnosed in 34 (15%) patients. Staphylococcus aureus was the most common pathogen isolated and had the highest rate of progression from VAT to VAP. Seven (21%) of the 34 patients were diagnosed with VAT that later progressed to VAP in averaged 3 days. Patients diagnosed with VAT had significantly more ventilator days (9 vs 6, p p < 0.001) and hospital days (22 vs 17, p < 0.001). No significant difference was observed in the clinical outcomes of the 25 VAT patients with timely, appropriate antibiotics compared to the 9 VAT patients who did not receive timely appropriate antibiotics. VAT was a risk factor for increased ventilator days, longer length of ICU and hospital stay. The time window from VAT to VAP allowed physicians to identify the pathogens and sensitivity profile needed to treat VAT with appropriate antibiotics. Data from well-designed studies were needed to assess the impact of early, appropriate antibiotic therapy for VAT, the choice of antibiotics, as well as the duration and route of administration.展开更多

Pneumonia is a common complication of inhalation injury, due to the increased susceptibility of lungs that have been stripped of their biologic defense mechanisms, as well as the general susceptibility of the burn population to infections. While older series suggest that pneumonia is associated with worse mortality and morbidity, recent reports suggest that this may not be the case in all populations. Methods: We attempted to clarify the impact of pneumonia in terms of mortality, length of mechanical ventilation, need for tracheostomy, and discharge disposition, in patients admitted with inhalation injury by performing a retrospective review of patients admitted to a regional burn center 2002-2009. Burn registry and electronic chart review were used to obtain demographic, clinical and outcome data. Univariate and multivariate analysis was used to compare outcomes in patients who developed pneumonia versus those who did not. Results: The study cohort comprised 166 patients, of whom 21 (13%) were diagnosed with pneumonia. Development of pneumonia was not predicted by age, surface area burned or other complications such as acute respiratory distress syndrome. Surprisingly, pneumonia was associated with reduced inpatient mortality (p = 0.006). However, patients who developed pneumonia were also more likely to have prolonged ventilator dependence (19 vs 5 days,展开更多
