Filter by:The goal of this study to evaluate whether eliminating the use of non-depolarizing neuromuscular blocking agents (NMBA) for maintenance of general anesthesia reduces postoperative pulmonary complications in higher risk patients.
The purpose of this study is to investigate the effect of oxygen concentration during alveolar recruitment on absorption ateletasis.
Protective ventilation strategy has been widely applied in the field of thoracic surgery requiring one-lung ventilation to reduce postoperative pulmonary complications. Low tidal volume, positive end-expiratory pressure (PEEP), and intermittent recruitment maneuver are key components of protective ventilation strategy. Recent evidence suggests that a tidal volume of 4-5 ml/kg should be applied during protective one-lung ventilation. However, optimal level of PEEP is still unclear. This study aims to investigate optimal level of PEEP to minimize postoperative atelectasis by comparing modified lung ultrasound score in patients applied protective one-lung ventilation using PEEP of 3, 6, or 9 cm of water during thoracic surgery.
Evaluate the effects of high-flow nasal oxygen therapy on atelectasis in the perioperative period by lung ultrasound (LUS) in bariatric surgery patients.
postoperative atelectasis observation by ultrasound after application of high flow nasal cannula oxygenation
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.
