Active clinical trials for "Pneumothorax"

The purpose of this trial is to study the role of small bore chest drains in draining traumatic hemothorax and pneumothorax.

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).

Endoscopic valve therapy is an effective therapy for patients with severe emphysema and low interlobar collateral ventilation. Although, valve therapy is a minimal-invasive treatment approach, it is associated with complications the most common of which is pneumothorax with a rate of 18-25%. Modifying post-operative medical care including bed rest for 48 hours after valve implantation may reduce the risk of post-interventional pneumothorax.

The purpose of this study is to evaluate the efficacy of manual aspiration in comparison to conventional chest tube drainage in pneumothorax therapy: whether manual aspiration will shorten hospital admission. whether the lung will expand by means of clinical and radiological findings.

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.

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.

Through this randomized controlled clinical trial, we aim to identify whether there is a difference in the incidence of 24 hour pneumothorax after chest tube removal, in two blindly randomized groups of patients: The first group with chest tube clamping 6 hours prior to removal, and the second group there will be no chest tube clamping. The data will be prospectively collected from patient records from the National Institute of Respiratory Diseases Ismael Cosío Villegas.

Collapsed lungs are common injuries after traumatic injury that regularly cause needless deaths despite being treatable with chest tubes. Properly used these tubes can be life-saving. Unfortunately, improperly used they can cause pain, bleeding, and other fatal complications themselves. Over the last few decades with increased use of CT scanning it is apparent that many small collapsed lungs are not seen on chest X-rays, and there is little guidance for the treating Doctors as to how to treat these patients. There is almost no good data that tells us whether these smaller pneumothoraces require treatment with chest tubes or whether they can simply be closely watched. This proposal is to carry out a simple trial of randomly assigning patients who do not appear to have any symptoms or problems from their occult pneumothorax to either having a standard chest tube or to being watched. Our careful review of the medical literature indicates that the investigators cannot honestly tell patients and their families which treatment is best or required. Our audit of current practice also indicates that Doctors in Calgary and across Canada, regularly prescribe both treatments regularly but in a hap-hazard. The patients in this study will be very closely watched in the intensive care unit and if they develop any breathing problems and do not have a chest tube in, then one will be inserted. The main results that the investigators are trying to determine with this pilot study, though, is whether the investigators are able to detect appropriate patients, to recruit them into such a study, and whether the guidelines the investigators have created to manage these patients in this study will be acceptable to all the patient's care givers. This data will help us to design a future large multi-centre trial that will hopefully provide information as how best to manage this type of injured patient.

The purpose of this study is to investigate whether if KatGuide (a new developed medical device) improves the placing of a large bore chest tube in the pleural cavity compared to the conventional method.

The investigators conducted a prospective randomized study to compare axillary minithoracotomy versus a modified two-port thoracoscopic technique for surgical pleurodesis in patients with recurrent spontaneous pneumothorax operated in a single institution. The main objective of the study was to investigate possible differences regarding short- and long-term clinical outcome between the two different techniques.
