Filter by:Background: Patients undergoing awake brain surgery are exposed to non-humidified, non-warmed oxygen/air mix flow through a face mask for a prolonged duration. This causes increased discomfort, inadequate breathing with the risk for hypoxia perioperatively. Humidified high flow nasal cannula (HFNC) oxygen therapy potentially improves patient comfort, oxygen/air exchange, improves surgical conditions and prevents atelectasis of the lung, compared to traditional oxygen administration using a face mask in patients undergoing awake brain surgery. Results of this trial will be used to initiate a more extensive, multicenter trial to further characterize the potential impact of HFNC.
spontaneous breathing on occurrence of atelectsis in infants
Morbid obese patients present changes in respiratory physiology caused by weight overload. Intraoperative atelectasis is a pulmonary complication that affects not only gas exchange but also respiratory mechanics. The present study was aimed to test the role of different parameters for monitoring the treatment of atelectasis by a lung recruitment maneuver.
The purpose of the protocol is to assess how incentive spirometer data gathered via a smartphone platform can be utilized to improve participant adherence to prescribed incentive spirometer exercises in the post-operative period. Half of the participants will receive a standard of care incentive spirometer with a passive tracking device while the other half of the participants will receive a smartphone connected device and smartphone with an application that will encourage their use.
This is a randomized crossover trial to evaluate the effects of thoracic compression applied alone or in association with hyperinflation maneuver with the ventilator. In addition, the mobilized volume and peak expiratory flow resulting from both maneuvers will be evaluated.
In this study researchers aim to evaluate effect of different ventilation modalities on the developments of atelectasis by using ultrasound.
The study aims to compare the degree of atelectasis between ultrasound-guided alveolar recruitment group and conventional alveolar recruitment group in patients receiving laparoscopic gynecologic surgery
Anesthesia causes respiratory changes and complications, which are the main causes of complications and anesthesia-related deaths. Among the complications, the rapid appearance of lung atelectasis is well known, deteriorating the hematosis during anesthesia, and inducing secondary pulmonary complications. Prevention or limitation of the atelectasis would be a way to improve the safety of patients who have a limited respiratory function. The application of a positive expiratory pressure (PEP) is an effective prevention method for atelectasis, that have been only demonstrate in patients under mechanical ventilation. The high flow nasal cannula is a non-invasive technique easy to perform and allowing a PEP. High flow nasal cannula is safe to use, and the interface is free from local skin complications. Chest X-ray (bad sensibility) or CT are usually used for the diagnosis of atelectasis, but these two exams involve irradiation for patient. MRI and pulmonary ultrasonography has now been validated in adults. MRI are relatively long, and allow to investigate the atelectasis with only a short additional acquisition time. Thus, it would be the first study on the effect of the PEP on the impact and the volume of the atelectasis during general anesthesia in spontaneous ventilation in children. By the way this is the first study on lung's anatomical effects of high flow nasal cannula. It is a monocentric, intervention, randomized, superiority study whose main purpose is to show the reduction of the atelectasis through the use of high flow nasal cannula versus a high concentration mask for pediatric anesthesia during MRI. The studied population is all the children between 6 months and 5 years with a pediatric indication of general anesthesia for MRI. The primary goal is to show a reduction of volume (cm3) of the atelectasis via the application of a PEP by high flow nasal cannula. The main assessment criteria is the ratio of atelectasis volume/total lung volume. The prevalence of the atelectasis will be evaluated by MRI lung and measured using 3D reconstruction software. The duration of the examination and the anesthesia is slighty lengthened, 3 to 5 minutes for a 40 minutes' exam. The secondary objective is to show a match between the atelectasis on MRI and 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.
During one-lung ventilation in thoracic surgery, the intensity of neuromuscular blockade may change the compliance and resistance of ventilated lung, thereby affecting postoperative atelectasis. The present study investigated the effect of the intensity of intraoperative neuromuscular blockade on the postoperative atelectasis using chest computerized tomography in patients receiving thoracic surgery requiring one-lung ventilation.
