Active clinical trials for "Pneumothorax"

This prospective randomized multicenter study is intended to investigate tolerance and effectiveness of thoracic drainage conducted by Seldinger technique with small drains, or by a surgical-like technique with large armed drains, in intensive care units patients.

The aim of this clinical trial is to compare the efficiency and analgesic use in the therapy of iatrogenic Pneumothorax when using the Pleuralvent™ system in comparison with large bore chest tubes (catheter 16F).

Knowledge about incidence, risk factors and genetic predispositions of primary spontaneous pneumothorax in young adults is very limited, and treatment has also been controversial.The Aim of this study is to optimize the treatment, estimate the actual incidence, and identify possible risk factors including genetic predispositions.

This study will compare the effect of HFNC versus standard oxygen administration after elective esophagectomy for cancer.

Pneumothorax refers to air in the pleural cavity (i.e. interspersed between the lung and the chest wall).1 Primary spontaneous pneumothorax (PSP) mostly occurs in healthy individuals without an apparent cause, probably due to the rupture of subpleural blebs located mostly on the apex of the lung or the apical segment of the lower lobe. Compared to PSP, a secondary spontaneous pneumothorax (SSP) occurs in the setting of underlying pulmonary disease, like COPD.2 Surgical treatment involves resection of apical bleb disease and pleurodesis which could be chemical or mechanical. Mechanical pleurodesis accomplished either via pleurectomy or pleural abrasion.3 In this study, we aim to compare the efficiency and recurrence risk of pleural abrasion versus pleurectomy in patients with Spontaneous pneumothorax.

The management of spontaneous large pneumothorax is not consensual. The current management involves the establishment of a Fuhrman catheter and an outpatient monitoring in pneumology consultation. Another alternative is widespread: simple exsufflation. However, no study has looked at the direct prospective comparison of these 2 treatments.

The study will be conducted as a, prospective, open label, non-inferiority, randomized controlled trial. In the intervention group; chest tube removal will be determined by air flow criteria as indicated by the digital drainage system data. In the control group removal will be determined by the same criteria of the digital drainage system but before removal, a chest tube clamping test will be performed. Primary outcome measure: recurrent pneumothorax after chest tube removal requiring chest tube reinsertion

Background: The Pleura is a double-layered membrane that surrounds the lungs. Pathological processes that involve the Pleura are called "Pleural diseases". Among them are included Pneumothorax (Air the chest cavity), Pleural effusions, and tumor formation. Ultrasound imaging of the Pleura to detect and assess pleural diseases has been proven as an excellent diagnostic and safe option. Ultrasound test uses sound waves to characterize the structure and function of different organs in health and disease. The standard technique used to create two-dimensional ultrasound picture is called Delay and Sum (DAS). Signals are transmitted and received from a series of elements and allow a two dimensional picture to be created. Because a large number of sensors is required, creating a two dimensional picture creates a large and usually redundant data pool. This fact leads to a need for stronger processors and larger operating systems, Consumption of higher energy, and hence an ungainly, slow, and expensive system. Signal Acquisition Modeling and Processing Laboratory (SAMPLE) in Weizmann institute has developed a data processing system that allows narrowing down the number of elements needed to process the ultrasound signal, while creating an ultrasound picture of abdominal organs in a satisfying resolution. Sometimes even better than standard methods. Research goal: Improvement of diagnosis and characterization of pleural diseases by Ultrasound, using a novel algorithm that was developed in SAMPLE laboratory in Weizmann Institute. The aim is to create a faster, more reliable ultrasound imaging while minimizing sampling rate and data volume. Methods: Tested population: Women and/or men who were diagnosed with Pneumothorax or Plural effusion with other imaging modalities, and healthy volunteers as a control group, Up to 30 participants per each group (Total up to 90), in a 1:1:1 Ratio. Research type: An open-labeled study. Experimental design: Participants that will meet the required conditions will be summoned to an exam in our imaging institute or will be scanned bedside, using the Verasonics ultrasound system, which allows free access to ultrasound raw Channel data. The information acquired, as well as other imaging scans of the participant, will be coded and delivered anonymously to SAMPLE laboratory for analysis.

Pneumothorax is the most common complication after CT-guided lung biopsy, and several techniques have been proposed to reduce the risk. Among them, rapid rollover is the maneuver to immediately reposition the patient, with biopsy-side down after removal of biopsy needle. It has been theorized that the technique reduces the size of alveoli surrounding the needle tract, leading to airway closure and reduction in the alveolar-to-pleural pressure gradient, thereby preventing pneumothorax. The aim of this study is to evaluate the effectiveness of rapid rollover in reducing the risk of radiographically detectable pneumothorax and the rate of chest tube insertion. Patients undergoing CT-guided lung biopsy for any indication will be recruited and randomized into either rapid rollover group or control group. In the control group, CT guided lung biopsy will be performed per standard protocols; in the rapid rollover group, the biopsy will also be performed per the same protocol with the addition of rapid rollover at the end of the procedure. For both groups, the primary outcome would be new or enlarging pneumothorax detected on post-biopsy radiographs, and the secondary outcome would be the risk of pneumothorax necessitating chest tube insertion, all complications associated with CT guided lung biopsy, time to complication development, and patient experience in each arm.

The goal of this study is to determine if cone beam computed tomography (CBCT) is a viable alternative imaging guidance modality for percutaneous transthoracic needle biopsy (PTNB) in a community hospital-based practice, and to determine the incidence of CBCT PTNB-associated pneumothorax compared to multidetector computed tomography (MDCT) guided PTNB biopsy. The standard of care in this facility is MDCT guided PTNB biopsy. The experimental arm of this study is CBCT-guided PTNB biopsy. This prospective study will identify patients planned for PTNB. Thereafter, data on lesion characteristics, imaging findings, and clinical history will be collected. Patients will be subsequently randomly assigned to undergo biopsy using either CBCT or MDCT guidance. This study will analyze the pneumothorax incidence between groups, and assess for associations between lesion size/location, pertinent imaging findings, and clinical risk factors.
