Active clinical trials for "Pneumothorax"

Investigators will compare two different approaches of postoperative drainage after the standard water-seal drain has been used efficiently; one is by using urine bag and check it get blown by the leaked air, two is by using clamping of the water seal drain. Investigators will compare them depending on several factors such as; cost effectiveness, hospital stay, duration of putting the drain and more, reinsertion of the chest tube and others.

Endotracheal intubation is a life-saving intervention that few infants need after birth. Although an endotracheal tube is the most reliable way of providing positive-pressure breath, the critical factor that determines the maximal efficacy of positive-pressure ventilation is the optimal placement of the endotracheal tube tip. There are various methods available to determine the initial depth of endotracheal tube (ETT) that are based on the infant's birth weight, gestational age, anthropometric measurements, and others include vocal cord guide and suprasternal palpation methods. The Neonatal Resuscitation Program (NRP) textbook, in its 7th edition of the textbook, recommends a gestational age chart and nasal-tragus length method for estimating endotracheal tube insertion depth during cardiopulmonary resuscitation of the neonate. The evidence to support these two methods is, however, limited. Hence, we designed this study to determine the accuracy of two methods, gestational age chart and nasal-tragus length method, recommended by the Neonatal Resuscitation Program.

Primary spontaneous pneumothoraces (PSP) represent a significant public health problem, occurring in young healthy subjects without pre-existing lung disease or precedent medical intervention or trauma with a reported incidence of up to 18-28/100 000 per year. PSP treatment often requires thoracic surgery to restore lung expansion and to prevent de novo lung collapse. Despite the presence of elaborated guidelines by the British Thoracic Society (BTS) postulating apical wedge resection of the lung and total parietal pleurectomy (WRPP), the majority of German hospitals gathered experience especially in limiting surgery to cost-saving partial apical parietal pleurectomy or yet apical pleural abrasion (PP). Until today, hardly any reliable data exist to analyze and compare the varying treatment approaches regarding efficacy and efficiency. In this randomized, multi-centric clinical trial, both treatment approaches will be compared. For this purpose, candidates for surgery will be randomized into one of the two treatment groups after informed consent has been obtained. Patients will be followed for 2 years by the participating centres to be able to evaluate the long-term effect of the surgical interventions.

Guidelines lack high quality evidence on optimal postoperative chest tube and pain management after surgery for primary spontaneous pneumothorax (PSP). This results in great variability in postoperative care and length of hospital stay (LOS). Chest tube and pain management are prominent factors regarding enhanced recovery after thoracic surgery, and in standardised care they are crucial to improve quality of recovery and decrease LOS. Historically, postoperative chest tubes are left in place for at least a fixed number of 3-5 days, irrespective of absence of air leakage. This period was deemed necessary for adequate pleurodesis and prevention of recurrence. However, it is suggested that removal on the same day of surgery is safe and associated with a reduced LOS. Regarding postoperative pain management, thoracic epidural analgesia (TEA) is the gold standard for postoperative pain management following video-assisted thoracic surgery (VATS). Although the analgesic effect of TEA is clear, it is associated with hypotension and urinary retention. Therefore, unilateral regional techniques, such as paravertebral blockade (PVB), are developed. The investigators hypothesize that early chest tube removal accompanied by a single-shot paravertebral blockade (PVB) for analgesia is safe regarding pneumothorax recurrence and non-inferior regarding pain, but superior regarding LOS when compared to standard conservative treatment.

This study will investigate the genetic cause of Birt Hogg-Dube (BHD) syndrome and the relationship of this disorder to kidney cancer. BHD is a rare inherited condition characterized by papules, or bumps benign tumors involving hair follicles on the head and neck. People with BHD are at increased risk of developing kidney cancer. Scientists have identified the chromosome (strand of genetic material in the cell nucleus) that contains the BHD gene and the region of the gene on the chromosome. This study will try to learn more about: The characteristics and type of kidney tumors associated with BHD The risk of kidney cancer in people with BHD Whether more than one gene causes BHD The genetic mutations (changes) responsible for BHD Patients with known or suspected Birt Hogg-Dube syndrome, and their family members, may be eligible for this study. Candidates will be screened with a family history and review of medical records, including pathology reports for tumors, and films of computed tomography (CT) and magnetic resonance imaging (MRI) scans. Participants may undergo various tests and procedures, including the following: Physical examination Review of personal and family history with a cancer doctor, cancer nurses, kidney surgeon, and genetic counselor Chest and other x-rays Ultrasound (imaging study using sound waves) MRI (imaging study using radiowaves and a magnetic field) CT scans of the chest and abdomen (imaging studies using radiation) Blood tests for blood chemistries and genetic testing Skin evaluation, including a skin biopsy (surgical removal of a small skin tissue sample for microscopic evaluation) Cheek swab or mouthwash to collect cells for genetic analysis Lung function studies Medical photography of skin lesions These tests will be done on an outpatient basis in either one day or over 3 to 4 days. When the studies are complete, participants will receive counseling about the findings and recommendations. Patients with kidney lesions may be asked to return periodically, such as every 3 to 36 months, based on their individual condition, to document the rate of progression of the lesions.

Pulmonary lymphangioleiomyomatosis (LAM) is a destructive lung disease typically affecting women of childbearing age. Currently, there is no effective therapy for the disease and the prognosis is poor. This study is designed to determine the disease processes involved at the level of cells and molecules, in order to develop more effective therapy. Researchers intend to identify the proteins and genes that contribute to the process of lung destruction in affected individuals.

The purpose of this study is to show that treatment with prophylactic autologous blood patch (ABP) after management of primary spontaneous pneumothorax (PSP) is feasible, reduces the incidence of prolonged air leaks, and reduces hospital length of stay. An ABP is a medical procedure that uses one's own blood in order to close one or many holes identified in the lungs. The blood modulates the pressure of the lungs and forms a clot, sealing the leak. Primary spontaneous pneumothorax is an abnormal collection of air in the pleural space between the lung and the chest wall.

To investigate the most preventable option to reduce primary spontaneous postoperative recurrence.

With the continuous strengthening of the concept of rapid rehabilitation, great progress has been made in minimally invasive thoracic surgery, and thoracoscopic surgery has developed rapidly. Double-lumen endotracheal(DLT) intubation is still the most reliable way of intubation in lung surgery. However, hypoxemia faced during double-lumen intubation still threatens the perioperative safety of thoracic surgery patients. In recent years, high-flow nasal oxygenation (HFNO) has great potential in the field of anesthesia, especially playing a new and important role in the prevention and treatment of short-term hypoxia and life-threatening airway emergencies. However, the use of HFNO in pulmonary surgery patients with poor pulmonary function lacks evidence-based basis, and there are few reliable clinical data. This study adopted a prospective, randomized, controlled, single-blind design. A total of 100 patients aged 18-60 years who underwent elective thoracoscopy-assisted pulmonary surgery were included and randomly divided into the experimental group: HFNO was used in the process of double-lumen intubation asphyxia; the control group: according to the traditional intubation process, No oxygen therapy equipment was used during intubation asphyxiation. The lowest blood oxygen saturation during intubation, the incidence of hypoxemia during intubation, perioperative complications, and postoperative hospital stay were compared between the two groups. This study explores the advantages of HFNO in complex endotracheal intubation, assuming that HFNO can improve the oxygen saturation of double-lumen intubation; optimize the intubation method of DLT, and tap its new potential to prevent and manage emergency airway crisis.

The PROSPECT study aims to look at the number of problems or side effects which occur after patients have had a procedure completed to remove fluid or air from the space between the lung and the chest wall. Other information will also be collected to see whether anything else affects which patients have problems after the procedure such as bleeding or infection. This study will also investigate whether it is possible to find out which patients are likely to feel a lot better after the procedure. Not all patients feel significantly better but it is not clear why this is. There are a number of different reasons patients may not feel better, for example if the lung is not able to fully re-expand. The study aims to look at whether it is possible to predict these problems before the procedure using ultrasound. If it is possible to find the answers to some of these questions it might be possible to prevent patients undergoing treatments which are not likely to benefit them. The study will use information already collected as part of clinical care, as well as questionnaires from patients receiving care at a variety of centres. The different features of these centres will also be considered in analysis.
