Active clinical trials for "Pulmonary Atelectasis"

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.

Anesthesia-induced atelectasis is a well-known entity observed in approximately 68-100% of pediatric patients undergoing general anesthesia. The collapse of dependent lung zones starts with anesthesia induction but can persist for hours or even days after surgery. Lung collapse is a pressure-dependent phenomenon. Each acinus has a critical closing pressure, i.e., the minimum transpulmonary pressure (Ptp) below that the acinus begins to collapse. While airway pressure is homogeneously distributed within all lung units, Pleural pressure increases along the vertical gravitational vector because of the lung's weight. As a consequence, the decreased Ptp in the dependent zones promotes collapse. This means that patients in the supine position suffer from increasing closing pressures in the ventral to dorsal direction. Alveolar recruitment maneuvers recruit collapsed alveoli, increase gas exchange, and improve arterial oxygenation. The investigators hypothesized that in children with anesthesia-induced atelectasis, postural changes have recruiting effects and improve lung aeration assessed by lung ultrasound.

Atelectasis occurs in patients of all ages who receive mechanical ventilation under general anesthesia, and although fatal cases are rare, it is known as a cause of postoperative hypoxia or fever. In pediatric patients, it has a particularly high incidence of 68-100%, and the incidence is inversely proportional to age. Pediatric patients,compared to adults, have a small capacity for functional residual capacity while a high metabolic demand, making them fundamentally vulnerable to hypoxia. Increased atelectasis during anesthesia causes hypoxia not only during anesthesia but also during recovery after anesthesia. Therefore, it is important to establish and apply a strategy to minimize the occurrence of atelectasis during mechanical ventilation under general anesthesia in pediatric patients. The aim of this study is to investigate whether pressure support ventilation at emergence period could reduce the incidence of postoperative atelectasis in infants undergoing surgery under general anesthesia.

The purpose of this study is to evaluate whether a therapy that uses a machine called a continuous high frequency oscillator (CHFO) is more successful at removing mucus than medications that thin out the mucus.

Evaluate the effect of chest manual compression technique (CCT) in the variables of oxygenation, hemodynamic and respiratory work in infants with respiratory diseases that are associated with atelectasis.

Statement of the problem: • Does the thoracic block technique has effect on arterial blood gases, vital signs and lung compliance in children with atelectasis on mechanical ventilation? Null hyposis there is no effect of thoracic block technique on arterial blood gases, vital signs and lung compliance in children with atelectasis on mechanical ventilation.

This study evaluates the omission of incentive spirometry use following bariatric surgery. Half of participants will receive an incentive spirometer while the other half will not. Oxygen saturation and pulmonary complications after surgery will be measured to examine the effectiveness of incentive spirometry.

The aim of this study was to investigate the effects of using positive pressure in the preoperative, intraoperative and postoperative morbidly obese individuals undergoing gastroplasty. It is believed that the application of these devices before, during or after surgery can help to improve the lungs and reduce pulmonary complications after surgery to reduce the stomach.

Often the decision for chest tube removal or trial of chest tube clamping is based on subjective assessment. This can lead to delay in chest tube removal. Recently, monitoring and recording of air leaks has been done using digital pleural drainage devices. This provides us with objective and continuous recording of air leaks as well as changes in pleural pressure. Our hypothesis is that the use of the ATMOS digital pleural drainage system will result in shorter hospital stay in comparison to traditional pleural drainage systems.

The Effectiveness of the Jamboxx Respiratory Therapy Device in Treatment of Patients with Decreased Respiratory Function is a proposal for investigation of the application of gaming to improving respiratory health. The Jamboxx device (see appendix A for device details) combines gaming with traditional incentive spirometry to provide users with a fun experience to keep them engaged in their respiratory therapy routine. The device allows users to play a series of mini-games that walk them through their routines. The Jamboxx also records airflow and lung parameters with an external mouthpiece attachment to provide users with real time feedback, and helps to assess increases or decreases in relative lung function over time. The Jamboxx has the potential to significantly impact the field of respiratory therapy by being one of the first gaming devices for patient therapy, and the first respiratory therapy gaming device that is accessible to users with limited mobility. Jamboxx provides a fun and engaging, low cost alternative to the traditional therapy techniques used and aims to improve patient compliance. This study addresses postoperative pulmonary atelectasis that results from diaphragm dysfunction and pain following upper abdominal surgery. This issue is a major cause of morbidity in these patients (Ford et al 1983). Incentive spirometry is used in this setting, but there is conflicting data regarding its effectiveness (Rupp et al 2013). Study 3 will focus on the questions regarding the influence of education and a novel use of a gaming device on prevention of atelectasis. Study 3 will include 3 subgroups of subjects. The first subject group will be enrolled in a nonintrusive observation only studies. Group 1 will explore the effect of technology via a tablet device on standard spirometry usage. Group 2 will look at the combined effect of technology via the tablet device and intensive education on compliance and reduction of post-surgical atelectasis. Finally, Group 3 will explore the effect of gaming technology with intensive educational reinforcement on compliance and reduction of post-surgical atelectasis.
