Filter by:We aim to show that systematic ultrasonography performed in ventilated patients suspected of ventilation-acquired pneumonia could improve the accuracy of diagnostic of pneumonia, and helps defining the diagnostic of tracheobronchitis when lower respiratory tract infection is considered. Chest CT scan is often performed before or just after admission in ICU, and usually show abnormalities that are revealed later on standard radiographs. This last exam is traditionally considered as the gold standard to prove new pulmonary infiltrates, but the correlation with parenchymal consolidation is pretty low, and lead to over-diagnosing pneumonia, thus leading to a massive and maybe sometimes unconsidered prescription of antibiotic therapy. Lung ultrasonography conducted systematically within the 3 first days after suspcion of pneumonia could help making the difference between real infection-linked lesions, and banal abnormalities following the hydric inflation of intra-thoracic organs, for instance pulmonary edema or pleural effusion. An independent evaluation using lung ultrasound, and analysis of CT scan acquisition when performed, compared with the physician in charge of the patient appreciation by suggesting him to provide his own probability of pneumonia upon routine clinical and biological datas.
The purpose of this study is to determine the efficacy, safety, tolerability, and pharmacokinetics (PK) of meropenem-vaborbactam compared to piperacillin/tazobactam for 7 to 14 days in the treatment of hospitalized adults who meet clinical, radiographic, and microbiological criteria for hospital-acquired bacterial pneumonia (HABP) or ventilator-associated bacterial pneumonia (VABP).
Mechanical ventilation has become one of the most important supportive treatment methods to save the life of critically ill children over time. Ventilator-associated pneumonia (VAP) is a common complication of mechanical ventilation. It is one of the leading causes of hospital-acquired infections in the Paediatric Intensive Care Unit (PICU).VAP can aggravate patients' condition and have adverse effect on mechanical ventilation. Moreover, VAP is associated with significant increased mortality. In those critical ill patients, the catabolism increased, the anabolism decreased, which can induce negative nitrogen balance. The consensus of optimal nutrition therapy in pediatric critical care in the Asia-Pacific, released in 2014, clearly recommended that early enteral nutrition support, which begin within 24-48 hours after admitting in PICU, can significantly reduce the prevalence and mortality of nosocomial infection. Intermittent enteral feeding and continual enteral feeding are the most common methods of enteral nutrition at present. There is no final conclusion about the association between enteral nutrition methods and VAP. Thus, the relationship between enteral feeding and VAP has long been a controversial issue. There is little clinical research on the correlation between enteral nutrition and VAP in children with mechanical ventilation, and mostly were observational studies which lacks strong evidence. How to choose the appropriate enteral nutrition remains an urgent need in PICU clinical work. Therefore, it is necessary for us to analyze the relationship between enteral feeding and VAP in critically ill children. This study would perform a two-year research with mechanical ventilated patients in PICU of four children hospitals in Shanghai, which aim to determine the relationship between different enteral feeding methods and VAP, to collect the baseline characteristic data of ventilated children, to analyze the risk factors for VAP in PICU patients. The results from our study would contribute to improving the standard of care for children undergoing mechanical ventilation, reducing their lung injury and improving prognosis.
The purpose of the study is to determine whether automated cuff pressure control results in a reduction in the proportion of patients developing ventilator associated respiratory infections during their stay in intensive care.
There is no accepted standard for the frequency of monitoring endotracheal tube cuff pressures (ETCP). Investigators plan on comparing two strategies for monitoring ETCP in mechanically ventilated patients. The two strategies will be the currently employed practice at Barnes-Jewish Hospital (BJH) which requires ETCP to be assessed immediately after the endotracheal tube is placed and after any manipulation of the endotracheal tube to include repositioning, manipulation of the cuff volume, or presence of an audible leak. Investigator will compare this current practice to a more intensive monitoring of ETCP which is employed at some hospitals and includes the same elements as noted in the current practice plus monitoring ETCP every work shift (every 8 hours or three times per day).
The purpose of this study is the prevention of Staphylococcus aureus pneumonia in mechanically ventilated subjects heavily colonized with S. aureus. Staphylococcus aureus is a human pathogenic bacterium that causes severe infections, including pneumonia and sepsis. Hospital-acquired bacterial pneumonia (HABP) caused by S. aureus, including ventilator-associated bacterial pneumonia (VABP) in mechanically ventilated subjects, is a significant public health threat despite efforts to optimize antibiotic treatment. ASN100 is an investigational monoclonal antibody product that targets the toxins produced by S. aureus to protect subjects from developing S. aureus pneumonia.
This study evaluates that P. aeruginosa, A. baumannii, K. pneumonia and Staph aureus which are obtained from patients' tracheal aspiration culture who treated with mechanical ventilation will be compared with Lactobacillus (LAB) members and nisin bactriocin in the laboratory. The aim is to investigate the probiotics' antimicrobial properties and effects on these bacteria's growth rate.
In this study; in patients undergoing mechanical ventilation, making the day series Endocan measurements during the first 5 day to look at whether there is a relationship between the levels of VAP with Endocan. This relationship, if any, aimed to investigate whether correlated with clinical and laboratory findings [presence of fever, pathological lung X-ray, the number of white blood cells (WBC), procalcitonin (PCT), C-reactive protein (CRP)] .
Few antimicrobials are available to treat ventilated associated pneumonia (VAP) caused by Gram negative multi-resistant (MDR) bacteria. Colimycin often remains the only active antibiotic. The aim of the study is to demonstrate the superiority of nebulized colimycin over intravenous colimycin to treat VAP caused by Gramnegative MDR bacteria.
Inappropriate antibiotic therapy in ventilator-associated pneumonia (VAP) is associated with increased mortality. The international guidelines recommend using broad spectrum antimicrobials especially in patients who received previous antimicrobials, with risk factors of muti-drug resistant (MDR) VAP or after 5 days of mechanical ventilation. Using broad-spectrum antibiotics for 48h until the results of conventional cultures and antimicrobial susceptibility testing (AST) are available, may promote the emergence of drug-resistant bacteria. Exposure to imipenem, as short as 1 to 3 days, is associated with a 5-fold increase in the risk of imipenem resistance in the gut microbiota of ICU patients (Armand-Lefevre AAC 2013). Performing AST directly on clinical respiratory samples would hasten the process by at least 24h. The diagnostic performance of a rapid method combining mass spectrometry and direct AST [DAST] are previously analyzed, and compared it with the conventional method (mass spectrometry with conventional AST [CAST]) and its potential impact was assessed on antimicrobial use in 85 patients (Le DORZE M et al - Clin. Microbiol. Infect. 2015). The results produced by the dast were useable in 85,9% of the cases and the sensitivity and negative predictive values of DAST were 100% for all antibiotics tested, except gentamicin (97.1% [95%CI = 93.3-101] and 97.4% [93.7-101], respectively) and amikacin (88.9% [81.7-96.1] and 96.4% [92.1-100.7], respectively), compared with CAST. Specificity and positive predictive values ranged from 82.9 (74.2-91.5) to 100%, and from 86.4 (78.5−94.2) to 100%, respectively. If results had been reported to the clinicians, that DAST would have saved carbapenem prescription in 17 cases (22%) and would have allowed immediate narrow spectrum antimicrobials in 35/85 (41.2%) cases. But, the benefit of DAST was based on a simulation and should be now tested in a randomized fashion. This project is a prospective multicenter study. The hypothesis is that, DAST compared to CAST, would increase the number of adequate antimicrobial therapy within 24 hours in case of late VAP (> 5 days under mechanical ventilation) with Gram negative bacilli (GNB) in IC patients while sparing carbapenems (imipenem and meropenem). The primary objective is to determine the impact of a strategy using DAST on the rate of day1 adequate therapy without carbapenems in case of late VAP due to GNB.
