Filter by:The primary aim is to develop a software algorithm that has the capacity to detect the normal 18 anatomical structures of the lung by using the position of the scope during the bronchoscopy procedure and using existing bronchoscopy technology.
Extracorporeal membrane oxygenation (ECMO) is a frequently used extracorporeal support measure during the intraoperative period in lung transplantation. A certain amount of anticoagulation, mainly unfractionated heparin (UFH), is used as part of ECMO support. One of the most common perioperative complications during lung transplantation is bleeding. An inadequately high dose of UFH can increase the risk of bleeding. In this study, the investigators hypothesised that a lower dose of UFH would decrease the risk of nonsurgical bleeding complications during lung transplantation and would not pose an increased risk of thrombotic complications for patients or ECMO circuits.
This feasibility study tries to define the value of daily Lung and Diaphragm Ultrasound in the early postoperative course following Lung transplantation by comparing its diagnostic accuracy with that of standard of care diagnostic procedures
In the current practice of lung transplantation, transplants are performed on a 24/7 schedule with a significant amount of procedures occurring overnight in order to minimize organ ischemic time. However, transplantation during the day time may lead to several advantages related to patient safety, including the presence of rested staff performing optimally, larger number of in-house professionals for emergency situations, and professional well-being. Advances and refinements in preservation practices have evolved to show that extended periods of preservation can be achieved without compromising outcome. Based on this, it is hypothesized that the avoidance of nighttime lung transplantation through prolonged pulmonary preservation will lead to at least similar patient outcomes compared to the current practice of 24/7 transplantation. During the period of this study, overnight transplants will be moved to a later start time (earliest 6AM). If lungs meet criteria for direct transplantation, they will be preserved with cold static preservation at 10°C within a special refrigerator. The maximum preservation time from donor cold flush to recipient anesthesia start time will be 12 hours.
Lung transplantation is an ultimate, effective treatment option for selected patients with end stage lung disease, improving quality of life and extending survival. Because of the improved survival during the last decades, enhancing the long term condition after lung transplantation has now become a focus for disease management. The co-presence of non-communicable diseases is common and poses new challenges to disease management. These comorbidities have been related to physical activity in the healthy population. As in other chronic respiratory disease, physical inactivity is a common feature of patients after LTX. Despite near normal lung function, exercise intolerance and physical inactivity persist up to years after the transplantation. Literature on effective interventions to increase physical activity are scarce in this population. Therefore, the present project aims to test the effectiveness of a tele coaching program to enhance physical activity and to analyze the association between physical activity and long-term health benefits in this population at risk. These research questions will be answered based on a randomized controlled trial. Patients that are active at baseline will be followed up in a cohort study.
Retrospective cohort study using routinely collected annual data on lung clearance index (LCI) in combination with clinical data to predict survival in patients with Cystic Fibrosis. The primary study endpoint is the association of LCI with the compound outcome survival or lung transplantation in patients with CF.
Infections are critical factors for the survival of critically ill patients. A serious problem is the high variability of antibiotic concentrations in critically ill patients. This may result in the risk of underdosage with possible ineffective therapeutic levels as well as in the risk of overdosage with possible adverse and toxic effects. Essential for the effectiveness of antibiotic therapy is the antibiotic concentration at target site. The goal of this study is to establish a method to extract Interstitial Lung Fluid (ILF) and Epithelial Lining Fluid (ELF) for antibiotic concentration measurements in patients following lung Transplantation and to calculate a tissue/serum concentration ratio. Improved knowledge regarding tissue penetration of Antibiotics may help to optimize drug dosing and management.
Pneumonias and lower respiratory tract infections can have important long-term consequences, particularly in the context of lung transplantation, where pneumonia is a major cause of death. Candidate organs and lung transplant recipients undergo bronchoscopic inspection to assess for lower respiratory tract infection, but traditional culture methods take time, leading to increased risk from inappropriate therapy. The investigators hypothesize that the rapid detection of lower respiratory tract infection, using a semi-quantitative multiplex molecular assay, can decrease the time to appropriate clinical decision making.
Severe exercise intolerance and shortness of breath are present in lung transplant candidates. Clinical features that reveal these symptoms in terminal period lung patients vary and are unclear. The effect of peripheral muscle strength on exercise capacity and dyspnea will be examined in our study.
Inspiratory Muscle Training (IMT), which is used to strengthen the respiratory muscles, is one of the techniques used in PR. It is mostly used in patients with chronic obstructive pulmonary disease, and has been shown to be beneficial for functionality and also for relieving dyspnea perception. It is reported in the guidelines that IMT has additional benefit for endurance in COPD patients. However, there are no studies related to its use and effectiveness in lung transplantation. In this study, investigators hoped to increase these known benefits by adding IMT to the standard Pulmonary Rehabilitation. There are two main objectives of this study: - to examine the effect of inspiratory muscle training on physical activity status and quality of life in lung transplantation candidates, - to compare physical activity and quality of life changes between the IMT+PR group and the PR group
