Active clinical trials for "Pneumothorax"

Perioperative changes in regional ventilation by pulmonary electrical impedance tomography and spirometry will be investigated in patients at risk for postoperative pulmonary complications. Those patients undergo abdominal and limb operations. In a pilot study arm electrical impedance tomography is tested in patients receiving osteosynthesis of serial rib fractures.

During general anesthesia, functional residual capacity (FRC) is reduced. If the FRC is lower than the minimum volume required to maintain the opening of the airways, there is a derecruitment of the lung parenchyma, leading to the phenomenon of expiratory flow limitation (EFL). The Driving Pressure (DP) is the difference between the plateau pressure (Pplateau) and the Positive End-Expiratory Pressure (PEEP), and estimates the lung strain. The incidence of EFL and the importance of DP are not known in adult cardiac surgery, so it's necessary a study to assess both. The primary end-point of the study is to evaluate the correlation of DP and EFL with PPCs in adult cardiac surgery. The secondary end-point of the study is to evaluate: the mechanical ventilation time, the length of ICU and hospital stay, the rehospitalization and mortality. It will be a prospective, observational, non-pharmacological study. It will enroll 200 patients undergoing elective adult cardiac surgery.

The goal of this study is to evaluate the sensitivity and specificity of Electrical Impedance Tomography (EIT) as a bedside diagnostic tool for lung pathologies in patients who are mechanically ventilated. In electrical impedance tomography low amplitude, low frequency current is applied on electrodes, and the resulting voltage is measured and used to computed the electrical properties of the interior of the chest as they change in time. The computed properties are used to form an image, which can then be used for monitoring and diagnosis.

It is aimed to examine the retrospective features of covid-19 patients followed in our hospital with pneumothorax.

To validate the benefits of recognizing asymmetric lung disease like atelectasis and pneumothorax in neonatal respiratory distress syndrome using electrical impedance tomography

Most pulmonologist request a routine chest-x-ray after bronchoscopy with transbronchial biopasie to exclude pneumothorax. We published a study in CHEST showing that routine chest-ray might not be necessary. We would like to conduct a propsective study to validate the results of the CHEST-study. Before and after the procedure follwing information will be collected: Age, Sex, Indication for procedure, number of biopsies and segment of biopsie, Saturation, Physical examination, Symptoms suggestive of pneumothorax. If there is no aggravation of the symptoms and/or physical examination after the procedure, as compared to before, routine chest-x-ray will NOT be done. A phone will be made 24 to 48 hours following the procedure to the patient.

This study will be conducted to determine the advantages and limitations of sonography compared with chest radiography, in the detection of post procedure iatrogenic pneumothorax in patients underwent to Pectus Excavatum (PE) with Nuss repair.

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.

Monocentric observational study of needle exsufflation for pneumothorax in the ICU.

Objectives To characterize mechanical ventilation practices during general anesthesia for surgery To assess the dependence of intra-operative and post-operative pulmonary complications on intra-operative Mechanical Ventilation (MV) settings
