Active clinical trials for "Pulmonary Atelectasis"

This study will compare an oxygenation test based on arterial blood gas analysis with computed tomography for estimating the extent of atelectasis.

Pre op ultrasound with chest auscultation and arterial blood gas, after extubation ultrasound with chest auscultation and blood gas, 12hrs chest auscultation with ultasaound, 24 hrs chest auscultation and ultrasound to see atelectasis

The purpose of this study is to describe the magnitude of respiratory complications after laparoscopic hysterectomy and cholecystectomy.

Evaluation of atelectasis that may be caused by different flow rate anesthesia applications during the operation with lung ultrasound score.

General anesthesia results in the development of atelectasis in the dependent areas of the lungs exposing patients to an increased risk of hypoxemia. During laparoscopic procedures, pneumoperitoneum increases already present atelectasis. Several methods have been suggested to reduce the impact of atelectasis during surgery. However, few intraoperative modalities for the diagnosis and monitoring of atelectasis are available. Lung ultrasound imaging is a promising non-invasive, non-radiant, portable and easy to use tool that as yet to be studied in the intraoperative setting. This observational study will aim to clarify the role of lung ultrasound imaging during laparoscopic surgery for the diagnostic and monitoring of atelectasis. This study is designed to: Demonstrate a link between the lung ultrasound aeration score, the partial pressure of oxygen in arterial blood (PaO2) / fraction of inspired oxygen (FiO2) ratio and the oxygenation index. In the event of intraoperative desaturation, study the impact of positive end-expiratory pressure (PEEP) and/or increase of FiO2 on the aeration score. Study the impact of pain on diaphragmatic function and the aeration score. Our hypothesis is that lung ultrasound imaging allows detection of lung aeration changes associated with induction of general anesthesia, pneumoperitoneum, emergence from anesthesia and changes occurring during the stay in the recovery room.

CT-PET image fusion has the potential to differentiate 'tumor' from 'atelectasis' much better than the CT-scan in patients with non-small cell lung cancer who also have atelectasis. This however has never been validated on a histological level. In this study patients with non small cell lung cancer and atelectasis who are eligible for surgery undergo a CT-scan and a PET-scan prior to surgery. The resection specimen will be compared to the preoperative imaging.

This study evaluates the influence of surgical and anesthesia-related variable on atelectasis formation during laparoscopic gynecologic oncologic surgery by lung ultrasound.

This trial studies how well radial-probe endobronchial ultrasound works in detecting the complete or partial collapse of the lung in patients undergoing peripheral bronchoscopy. Diagnostic procedures, such as radial-probe endobronchial ultrasound and bronchoscopy, use a thin, tube-like instrument inserted through the nose or mouth to view and take pictures of the inside of the trachea, air passages, and lungs.
