Filter by:Perioperative changes in regional ventilation by pulmonary electrical impedance tomography and spirometry will be investigated in patients at risk for postoperative pulmonary complications. Those patients undergo abdominal and limb operations. In a pilot study arm electrical impedance tomography is tested in patients receiving osteosynthesis of serial rib fractures.
To assess the effect and toxicity of intrapleural administration of hypertonic cisplatin for malignant pleural effusion in patients with non-small-cell lung cancer.
Chest physiotherapy (CP) facilitates the absorption of fluid in the pleural cavity and reduces the formation of fibrous adhesions in patients with pleural infection, allowing a faster clinical, functional and radiological improve. The aim of the study is to determine if the CP associated with conventional medical treatment (CT) improves functional sequelae secondary to pleural infectious.
Metastatic pleural effusion is a common complication of late-stage cancer and reduces the quality of life and survival of patients. The survival of patients with recurrent pleurisy by uncontrolled local or systemic treatment is less than 6 months. It is important to develop specific therapies to improve the quality of life and survival of patients with metastatic pleurisy. Bevacizumab is a monoclonal anti vascular endothelial growth factor (VEGF) which has proven effective in many indications in oncology. Vascular endothelial growth factor (VEGF) is an angiogenic factor which increases endothelial permeability. It plays a central role in many tumors of epithelial origin. In this context, it is legitimate to ask whether an antiangiogenic targeting VEGF may be effective in patients with metastatic pleurisy by decreasing local blood supply and over-permeability. No study has been interested in the intra-pleural pharmacokinetics of monoclonal antibodies and there are no predictive or prognostic biomarkers for metastatic pleural effusions. The investigators believe that intrapleural administration of bevacizumab will reduce the pleural vasculature permeability. It will neutralize VEGF present in pleural fluid and reduce the replenishment of effusion due to its prolonged half-life of 21 days. The investigators therefore propose a phase I study to determine the maximum tolerated dose and the recommended dose for phases II, studying the pharmacokinetics of intrapleural bevacizumab administered by an implantable device after evacuating a symptomatic metastatic pleurisy as part of a mammary carcinoma. The VEGF intrapleural levels and serum will be study and the time until a new puncture. Dyspnea will be evaluated as well as its impact on quality of life.
The purpose of this study is to determine if the addition of intermittent positive airway pressure breathing (specific lung expansion technique) to conventional chest physiotherapy chest drainage is effective to accelerate the reabsorption of pleural effusion and consequently decrease the duration of chest tube drainage and respiratory system impairment. These effects would decrease hospital stay lengths and the incidence of pulmonary complications.
The goal of this study is to evaluate the sensitivity and specificity of Electrical Impedance Tomography (EIT) as a bedside diagnostic tool for lung pathologies in patients who are mechanically ventilated. In electrical impedance tomography low amplitude, low frequency current is applied on electrodes, and the resulting voltage is measured and used to computed the electrical properties of the interior of the chest as they change in time. The computed properties are used to form an image, which can then be used for monitoring and diagnosis.
The purpose of this study is to determine whether a new catheter is safe and effective in treating malignant pleural effusions.
Pleural fluid glucose levels measured with bed-side point of care methods such as finger stick glucometers and I-STAT device correlate with the traditional in-lab testing methods.
Research project objectives. The project includes eight research hypotheses and eight corresponding study objectives. The most relevant objectives are: - Analysis of lung function and gas exchange parameters in relation to the removed pleural fluid volume and intrapleural pressure changes. - Evaluation of changes in lung and chest wall compliance and related changes in work of breathing during therapeutic thoracentesis and pleural fluid withdrawal. - Study of the relationship between intrapleural pressure changes and cardiac function assessed by echocardiography and alterations in serum natriuretic peptide A and B concentration. - Comparative analysis of the reliability of the volume-pressure curve slope prediction based on different variables measured before thoracentesis and real measurements of ventilation and intrapleural pressure during thoracentesis. 2. Research methodology The study will be performed in 60 patients with pleural effusion planned for therapeutic thoracentesis. Studies before thoracentesis: body plethysmography, spirometry, lung diffusion capacity (DLCO), arterial blood gases, 6 minute walk test, echocardiography, serum natriuretic peptide concentration. Evaluation during thoracentesis: continuous measurement of tidal breathing and respiratory rate, measurement of removed pleural fluid volume and intrapleural pressure, transcutaneous measurement of PO2 and PCO2. Pleural catheter will be retained for the next 48hours to enable fluid drainage and intrapleural pressure measurement after completion of thoracentesis. Monitoring during 48-hrs after thoracentesis: pre-thoracentesis measurements will be repeated in specific time points and compared in two subgroups (active physiotherapy to improve lung re-expansion and passive lung re-expansion). Intrapleural pressure will be measured 24 and 48 hours after thoracentesis. Then, the catheter will be removed. Analysis.Signal analysis and visual multidimensional analysis performed with the use of own computer programs will be the first step of the analysis. The identified relationships between the analyzed parameters should allow to form physiological, medical, and statistical hypotheses, as well to verify the analysis of previously obtained data . Expected impact of the research project The study results will allow to define lung function, blood gases and cardiovascular function in relation to changes in intrapleural pressure. Some of these correlations had not been previously investigated. Our results may influence management standards in patients who require therapeutic thoracentesis.
