Active clinical trials for "Pneumothorax"

There was no evidence that the number of chest tube do effect to the recurrence of pneumothorax, which placed after thoracoscopic wedge resection together with mechanical pleurodesis.This study evaluates the efficacy of single chest tube versus multiple tubes drainage in spontaneous pneumothorax after VATS bullectomy and pleurodesis. After routine procedure the participants will randomized to either placed single chest tube or multiple chest tubes

The aim of this study is to evaluate the role of nitric oxide on pulmonary vasculature and right ventricular function in postoperative cardiac surgery patients.

Sunnybrook Health Sciences Center annually provides assistance to approximately 600 cardiac surgeries and 1500 trauma patients, many of whom require chest tubes to prevent blood and fluids from accumulating in the pleural cavities surrounding the heart. During the removal of chest tubes, there is a risk of air leaking into these cavities, leading to pneumothorax, a critical condition occurring in approximately 5-26% of cases, associated with increased complications and mortality. Currently, the diagnosis of pneumothorax is primarily based on chest X-rays (CXR), despite their limitations and low reliability. As an alternative method, lung ultrasound (LUS) offers several advantages: it is safer, less expensive, and less painful for patients compared to CXR. However, there is a lack of comparative data on the accuracy and interrater reliability of these two diagnostic approaches after chest tube removal. This study aims to evaluate the accuracy of lung ultrasound performed by medical trainees in diagnosing pneumothorax in cardiac and trauma patients. By comparing LUS to CXR, the investigators seek to determine if LUS provides a more reliable and precise diagnosis. This study has the potential to enhance patient care by establishing a more effective and accessible method for diagnosing pneumothorax post-chest tube removal.

Intrapleural pressures have been shown to be a useful clinical predictor in pleural effusions, however it's utility has not been described in pneumothorax. Data on intrapleural pressures in pneumothorax are limited. Furthermore, the pleural pressure in tension pneumothorax is theorized to be greater than atmospheric pressure, though this has never been verified. Pneumothorax is primarily treated with a tube thoracostomy. This observational study will record intrapleural pressures in participants with pneumothorax undergoing a tube thoracostomy. Clinical outcomes of participants will then be monitored for need for pleurodesis, intrabronchial valve placement, and video assisted thoracoscopic surgery (VATS) to identify a correlation with intrapleural pressure.

The number of lung biopsies has increased steadily in recent years. Pneumothorax is the most common complication of a lung biopsy and can occur during the procedure, immediately after the procedure or within a few hours (delayed pneumothorax). The incidence of pneumothorax in the literature is very different from one study to another: it has been reported to be from 9 to 54% in patients undergoing percutaneous transthoracic needle biopsy. This difference of incidence could be explained by the absence of consensus for the definition of an iatrogenic pneumothorax. The characteristics of pneumothorax and the management of patients with iatrogenic pneumothorax will be evaluated in different centres in a retrospective manner. This study will contribute to refining the criteria for defining pneumothorax occurring during lung biopsy and will provide a better understanding of the condition and its management.

The Chang Gung Pneumothorax Detection Software is a medical software that can automatically detect whether there is a pneumothorax in Chest X-Ray. The purpose of this study is to verify whether the Chang Gung Pneumothorax Detection Software can correctly identify patients with pneumothorax in Chest X-Ray. The results of the software analysis will be used for the performance of the software on the primary and secondary outcomes.

Pneumothorax can be fatal if treatment is delayed or the pneumothorax is refractory. However, the mortality rates and their risk factors were mainly reported from retrospective studies, and local data regarding the mortality of spontaneous pneumothorax is scarce. This study aims at evaluating the in-hospital mortality and relevant clinical outcomes of spontaneous pneumothorax and identifying their predictive factors. The data collected from this study will also guide the planning of subsequent research to overcome the knowledge and service gap in managing spontaneous pneumothorax.

All calls that end up on the out-of-hours general practitioners' service (OHGPS), which contain a demand for an urgent home visit, are passed on to the on-call general practitioner (GP). These calls are randomized into two arms: after the patient's informed consent, they are assigned either to one arm where the monitoring device, PICO, is applied together with the GP's general care or to the other arm where only the usual care is provided. All data such as suspected diagnosis, treatment or referral, influence of the parameters, ECG and/or alarms on the management and the user-friendliness are recorded. After 30 days, the diagnosis and evolution is requested from the patient's own GP or, if referred to a hospital, in the hospital in order to be able to compare the effect of the approach by the GP between both arms. The aim is to investigate if 1/ the use of the PICO monitoring device could improve GPs' decisions to refer to hospital or not in urgent cases; 2/ there is a difference between the diagnosis with and without the use of the monitoring device using the final diagnosis by the electronic health record of the own GP of the patient; 3/ the call to send a GP for an emergency contained sufficient information for the OHGPS phone operator to take an appropriate decision; 4/ the build-in alarms help the GP during his intervention; 5/ the PICO is easy to use during an emergency; 6/ the use of the device makes them feel more confident in transmitting the information to the Medical Emergency Team.

This study aims to evaluate the efficacy of single dose analgesia in combination with local anesthesia to control pain during Trans Ultrasound guided procedures. It also aims to assess the effect of its use on procedure performance time and rate of complications occurrence compared to local anesthesia alone.

The purpose of this study is to compare the effectiveness of two treatment strategies--delayed versus immediate surgery-- for children with primary spontaneous pneumothorax (collapse of the lung). Currently, both treatment modalities are used and there is no clear evidence that either option is superior. The investigators hypothesize that immediate surgery will have better outcomes with lower recurrence rates than delayed surgery.
