Filter by:The purpose of this trial is to study the role of small bore chest drains in draining traumatic hemothorax and pneumothorax.
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 compare two methods that are currently used at the end of a CT guided lung biopsy to close the hole on the surface of the lung in order to minimize the chance of air leaking out of the hole. The two techniques consist of either injecting a very small amount of your the blood called a blood patch into the biopsy hole or injecting a gel-based FDA approved artificial plug called BioSentry that will eventually get absorbed into the body.
Investigators compared the patients' subjective postoperative symptoms and complications between the double lumen endotracheal intubated patients under general anesthesia and non-intubated patients under sedation and local anesthesia including 1. postoperative Visual scale of pain 2. postoperative sore throat/voice change 3. postoperative nausea/vomiting 4. intraoperative Arterial blood gas analysis 5. cost for anesthesia 6. morbidity
The use of wire-guided Arndt® endobronchial blocker does not gain widespread acceptance during video-assisted thoracoscopy (VATS) because it takes longer time to collapse the operative lung especially in patients with chronic obstructive lung disease (COPD). The use of a disconnection technique for deflation of Arndt® blocker had a comparable degree of lung collapse with the use of double-lumen tubes. However, it carries a risk of blood or infected secretions contaminating the dependent lung. We hypothesise that the use bronchial suction of through a barrel part of a 1-mL insulin syringe attached to the suction port of the bronchial blocker would be associated with comparable time to optimum lung collapse with the disconnection technique. After ethical approval, 58 patients with spontaneous pneumothorax scheduled for elective VATS using Arndt blocker® for lung separation will be included in this prospective, randomized, double-blind study. Patients will be randomly assigned to deflate the blocker with either disconnecting the endotracheal tube from the ventilator for 60 s. prior to inflation of the bronchial blocker allowing both lungs to collapse, or attaching -20 cm H2O of suction to the suction port of the blocker through the barrel part of a 1-mL insulin syringe (n = 29 for each group).
The purpose of this study is to determine whether the use of negative pleural suction in tube thoracostomy is more effective than water seal alone for the treatment of pneumothorax and/or hemothorax in patients with chest trauma.
One lung ventilation (OLV) is accomplished with a double lumen tube (DLT) or a bronchial blocker (BB). In this study, the investigators compared the effectiveness of lung collapse using DLT, BB with spontaneous collapse, and BB with disconnection technique.
Often the decision for chest tube removal or trial of chest tube clamping is based on subjective assessment. This can lead to delay in chest tube removal. Recently, monitoring and recording of air leaks has been done using digital pleural drainage devices. This provides us with objective and continuous recording of air leaks as well as changes in pleural pressure. Our hypothesis is that the use of the ATMOS digital pleural drainage system will result in shorter hospital stay in comparison to traditional pleural drainage systems.
Malignant pleural mesothelioma (MPM) has a growing incidence and in spite of early diagnostic, their outcome remains dismal. The evolution of MPM is often local with rare distant metastases. There is now a sizable body of evidence that metastases could develop from circulating tumor cells (CTC) spread in blood before or during surgery. Thus, sensitive and specific detection of CTC in blood is considered as a potentially relevant predictive biomarker for patients with carcinomas. In exchange, the prognostic value of CTC in MPM has not yet been evaluated. Indeed, the main goal for preoperative detection of CTC is to identify patients with high risk of recurrence after surgery, in order to perform more adapted therapeutic strategy. Despite several studies reported about CTC detection, methodological aspects concerning sensitivity, specificity and reproducibility have prevented a clear appraisal of their clinical impact. Thus, the aim of our study is to evaluate the presence and the prognostic value of CTC in MPM by a double approach. In our setting, cytopathological analysis of circulating non hematological cells (CNHC), of epithelial origin, isolated according to their size (ISET, Isolation by Size of Epithelial Tumor cells) along with immunomagnetic selection, identification and enumeration of circulating epithelial cells in peripheral blood (CellSearch method) is considered a promising approach.
The purpose of this research is to see if people who have had a collapsed lung that has been re-expanded can be safely taken to an elevation that a person might experience while in a commercial airplane without having their lung partially collapse again, or have any symptoms such as feeling short of breath or having oxygen levels in the blood decrease while at the simulated altitude. The investigators hypothesize that subjects who have had a collapsed lung that has been re-expanded will not have any adverse symptoms or signs while subjected to a simulated altitude of 8400 feet (565mm Hg) or 12650 ft (471mm Hg).
