Filter by:In a recent experimental study, the investigators showed that the growth factor Activin A is expressed in the lungs of rats with the acute respiratory distress syndrome (ARDS) at levels that are comparable with those determined in the bronchoalveolar (BAL) lavage fluid from patients with ARDS. In the same study, the administration of the Activin A inhibitor Folistatin resulted in attenuation of the histological damage of the ARDS-afflicted rat lung. The precise role of Activin A/Folistatin in acute respiratory failure associated with acute lung inflammatory pathology has not been elucidated yet. Therefore, the purpose of the present, observational study is to investigate the role of Activin A/Folistatin in respiratory failure due to ARDS and/or ventilator-associated pneumonia (VAP), also in relation with other biochemical markers, such as cytokines and surfactant-related proteins.
There might be additional benefit on clinical outcomes from adjunctive colistimethate sodium inhalation as therapy for multidrug resistant Gram-negative ventilator-associated pneumonia.
Critically ill patients whose lungs are supported by breathing machines (ventilators) commonly develop a new lung infection, called ventilator-associated pneumonia (VAP). Because VAP is often fatal, antibiotics are administered whenever it is suspected. However VAP is hard to distinguish from several non-infective lung conditions and most patients with suspected VAP do not have pneumonia. Therefore many patients receive unnecessary antibiotics for several days, promoting emergence of 'superbugs'. Laboratory test results for diagnosing VAP typically only reach the doctors after 3 days. A simple test rapidly and confidently excluding VAP should improve patient care, reduce unnecessary antibiotics and decrease costs. We recently showed that low levels of specific proteins in fluid from the lungs of patients with suspected VAP effectively excluded VAP, using a test that may yield results within 6 hours. The test used is an extension of existing technology produced by our commercial partner Becton Dickinson (BD) Biosciences. Our previous findings were derived from a single hospital's intensive care unit. We have recently confirmed this finding across many intensive care units, which will help show that the test can be used in 'real life'. The aim of this study is to take the new test to the next step and determine whether it can improve the care of patients by reducing the amount of unnecessary antibiotics prescribed. This will be done using a 'randomised controlled trial', the best tool for scientifically testing a new diagnostic test. To do this we shall identify patients with suspected VAP, all of whom will have a lung sample - half of the patients will receive 'usual care' for suspected VAP, the other half will have the new test performed on their lung fluid. If the new test suggests no lung infection, the doctors will be asked to consider not giving antibiotics. We shall test how much antibiotic is given to each group.
The investigators hypothesized that PVC tapered-cuff tracheal tubes would reduce microaspiration of gastric content as determined by pepsin level in tracheal aspirate.
Many hospitals employ a common canister inhaler protocol in patients that do not require mechanical ventilator support. Common canister refers to a single inhaler paired with standardized cleaning methods for use on more than one patient. Small reports suggest that this method does not pose an increased infectious risk and is associated with significant cost savings. Common canister protocols offer a solution to the discordance between inhaler sizes and average inpatient use of the drugs. Metered dose inhaler canisters are contain enough drug for several days to weeks of daily use. However, the average length of stay for most inpatients is only several days. Therefore, most inpatients do not use all of the canister contents, an unused resource that is potentially wasted. The common canister approach has not been previously described in mechanically ventilated patients (people requiring intensive care unit admission on breathing machines). This study aims to assess the safety of common canister utilization by assessment and comparison of infection rates in the study and control group.
A simplified graded gut decontamination protocol combined with rigorous bi-weekly screening and appropriate bacterial prophylaxis, will lead to a 25% reduction in the acquisition of blood stream infections and to a 25% reduction in lower airway colonization with multi drug resistant organisms. There will be no concomitant rise in gram-positive or fungal infection or a surgency of new resistance patterns.
The primary objective of this study is to evaluate the effectiveness and feasibility of the implementation of revised standards of care for oral hygiene (SAGE Q-care q2 Oral Cleansing and Suctioning System with and without chlorhexidine gluconate) relative to the current routine standard of care in mechanically ventilated patients admitted to the adult Intensive Care Units in Alberta Health Services Calgary Zone. This pilot study will evaluate the feasibility of performing a larger definitive study. The primary assessment of effectiveness for the definitive study will be the proportion of patients who develop ventilator-associated pneumonia.
Ventilator-associated pneumonia (VAP) is a common complication of mechanical ventilation associated with significant morbidity, including prolongation of mechanical ventilation and increased ICU and hospital length-of-stay. Numerous strategies have been proposed to decrease the occurrence of VAP among ventilated patients. Most notably, optimizing the use of daily sedative interruptions and daily spontaneous breathing trials can improve sedative management, decrease ventilator time, improve outcomes for mechanically ventilated patients,and possibly decrease VAP.Combining daily sedative interruption with daily spontaneous breathing trials confers additive improvement in ventilator days, intensive care days, and possibly mortality compared to daily spontaneous breathing trials alone. The primary aim of this study is to determine the impact of an opt-out protocol for paired daily sedative interruptions and spontaneous breathing trials on VAP rates using a new streamlined VAP definition. The investigators will evaluate the responsiveness of CDC's proposed new surveillance definitions for ventilator-associated events to this quality improvement initiative. The study will be nested within the Epicenters Streamlined versus Conventional VAP Surveillance Study. Nine of the 18 hospitals in the larger study will be participating in this intervention arm.
Ventilator-associated pneumonia (VAP) is an important cause of morbidity and mortality in ventilated critically ill patients specially in intensive care unit (ICU). It is associated with an increased duration of mechanical ventilation, high death rates and increased healthcare costs in China. However, VAP is preventable and many practices have been demonstrated to reduce the incidence of this disease, but the morbidity is still so high. So much more methods of prevention should be needed to reduce the incidence of VAP. Statins (3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors) present anti-inflammatory and immunomodulatory effects besides their ability to regulate cholesterol composition. So it is hypothesized that early use of statin may prevent some of the infection disease such as VAP. Actually, Two studies have showed that statin treatment is associated with reduced risk of pneumonia. However, the relationship between statins and reduced risk of pneumonia is not consistent. After reviewing some of the guidelines,meta analyses and system reviews, the investigator find that advanced age,immune suppression from disease or medication and specially depressed level of consciousness are the risk factors of VAP. So the investigator assumes that early use of statin may give us a favorable outcome in the patients with coma or in the patients with severe disease (Acute Physiology and Chronic Health Evaluation II score > 15 or Glasgow coma score < 7). In addition there is no prospective study to investigate the role of statins in VAP in the patients with ischemic stroke. The investigator hopes that this study can approve the relationship between statins and reduced risk of VAP in the patients with ischemic stroke. And it can improve the processes,outcomes and costs of critical care as well.
The purpose of this study is to determine which humidification system is more effective in preventing pneumonia in mechanically ventilated patients. The study will compare a heat and moisture exchanger versus heated humidification.
