Filter by:Transthoracic lung biopsy (TLB) provides a histological diagnosis of nodule or lung mass. Pneumothorax is the main complication of TLB with an average of 20%. Many risk factors, whether clinical, computed tomography or related to TLB, are described in the literature. The British Thoracic Society recommends monitoring for 2 hours after the procedure with a possible discharge if the chest X-ray is normal. There is no French or European recommendation for monitoring the occurrence of pneumothorax after TLB. In the university center of Besançon, France, a minimum supervision of 4 hours is recommended and approximately one in two patients is hospitalized until the following day to reach this minimum time of 4 hours. The objective of the SPOT study is to perform a predictive score of pneumothorax from a retrospective cohort of patients for whom a transthoracic lung biopsy was performed and to validate this score on a prospective cohort. The expected goal is to select patients who can benefit from outpatient care by shortening the post-procedure surveillance period and to monitor more long-term only high-risk patients.
Spontaneous pneumothorax is a common condition which is defined as air presence inside of pleural space. Despite, several studies that have been carried on management patients suffering spontaneous pneumothorax, the first step approach on patients is still the topic of debate. Since chest tube drainage and needle aspiration are widely used first step techniques in spontaneous pneumothorax, current study compares the efficacy of abovementioned techniques, as well as long-term outcomes. In current multi-center single-blinded RCT, all patients admitted with spontaneous pneumothorax will be enrolled study and written consent form provided by patients, simultaneously. Patients randomly assigned to study groups including (A) chest tube drainage and (B) needle aspiration. Subsequently, all patients will undergo one-year follow-up and will be evaluated in terms of treatment success rate and pneumothorax recurrence. Hypothesis of present trial are as follows: a) repetitive needle aspiration may lead to higher treatment success rate in patients with primary spontaneous pneumothorax, in comparison to chest tube drainage, b) needle aspiration may result in reduction of hospital admission duration in patients with primary spontaneous pneumothorax compared to chest tube drainage, c) the rate of spontaneous pneumothorax recurrence during one-year follow up might be lower in patients who undergo needle aspiration instead of chest tube drainage.
This study is designed to assess whether a new type of chest drain reduces the number of drains that fall out of or are accidentally removed from the chest cavity (usually requiring another drain to be inserted), without causing any increase in discomfort or other side-effects.
To assess the prevalence of BHD (Birt-Hogg-Dubé syndrome) among patients with spontaneous pneumothorax. Patients who were treated for primary spontaneous pneumothorax in Rijnstate hospital are to be included. Patients will receive a questionnaire. When given consent, the investigators will invite them for a one-time visit to the out-patient clinic. Patients will be asked for a blood sample to determine pathogenic FLCN (folliculin) mutations and a pulmonary CT scan for evaluation of presence of lung cysts.
Endobronchial ultrasound (EBUS) is a technique that uses ultrasound along with bronchoscope to visualize airway wall and structures adjacent to it. Pneumothorax is a known complication from EBUS procedure. To rule out a Pneumothorax after the procedure, a Chest -X-ray is usually done. Point-of-care sonography has emerged as an invaluable tool in the assessment of patients with both traumatic and non-traumatic dyspnea. Multiple studies involving bedside ultrasound has shown that a pneumothorax can easily be ruled out if pleural sliding sign or B lines are visualized on lung ultrasonography; the accuracy of lung ultrasound in ruling out pneumothorax approach computed tomography and exceed plain radiography. Preforming a lung ultrasound using the EBUS bronchoscope tip as a way to rule out pneumothorax has never been described previously. If this is possible it will obviate the need of getting a Chest -X-ray and decrease the dose of radiation that the patient is exposed to. In this study we will demonstrate that the feasibility of using the transducer of the EBUS Bronchoscope to perform bedside lung ultrasound to rule out pneumothorax.
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.
The study aims to determine the level of knowledge and skills to recognize and decompression of tension pneumothorax
This subject analysis of the influence of the dissociating inferior pulmonary ligament on pulmonary reexpansion and recurrence in the treatment of primary spontaneous pneumothorax by video assisted thoracic surgery. All patients are randomly divided into two groups: group A and group B. Wedge resection(WR) will be performed for all patients. Investigators dissect the inferior pulmonary ligament(DIPL) for group A. Investigators do not dissect the inferior pulmonary ligament for group B. The pulmonary reexpansion and recurrence rate are observed between the two groups.
The purpose of this study is to determine whether injecting autologous blood or putting bronchial plug through bronchoscope is effective in the treatment of refractory pneumothorax.
Background There is no unanimous opinion about a lung-protective strategy in cardiac surgery. Small randomized clinical and animals trials suggest that ventilation during cardio-pulmonary bypass (CPB) could be protective on the lungs. This evidence is based on surrogate end-points and most of studies are limited to elective coronary surgery. According to the available data, an optimal strategy of lung protection during CPB cannot be recommended. The purpose of the CPBVENT study is to investigate the effectiveness of different ventilation strategies during CPB on post-operative pulmonary complications. Trial design The CPBVENT study will be a single-blind, multicenter, randomized controlled trial. We are going to enroll 780 patients undergoing elective cardiac surgery with planned use of CPB, aortic cross-clamping and two lung ventilation. Patients will be randomized into three treatment groups: 1) no ventilation during CPB; 2) continuous positive airway pressure (CPAP) with positive end-expiratory pressure (PEEP) of 5 cmH2O during CPB; 3) ventilation with 5 acts/minute with tidal volume of 2-3 ml/Kg and a PEEP of 3-5 cmH2O during CPB. The primary end-point will be the incidence of a PaO2/FiO2 ratio <200 until the time of discharge from the ICU. The secondary end-points will be the incidence of post-operative pulmonary complications and 30-days mortality. Patients will be followed-up to 12 months after the date of randomization. Summary The CPBVENT Trial will determine whether different ventilation strategies during CPB will improve pulmonary outcome in patients undergoing cardiac surgery.
