Active clinical trials for "Pulmonary Atelectasis"

The overall objective of this study is to describe the incidence of postoperative pulmonary complications in patients with a positive and negative AIR-test result. Second, the investigators wish to describe the incidence of a positive AIR-test and its association with the development of PPC. In addition, the investigators aim to describe whether mechanical ventilation strategy differs between patients with a positive and negative AIR-test.

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.

An Investigation to determine the single-use scope's ability to suction secretion from the lungs to resolve the collapse of the lung.

This prospective randomized comparative study, to assess post-operative lung atelectasis by comparing calculated lung score using ultrasound between pediatric patients intubated with LMA (laryngeal mask airway) under volume versus pressure controlled modes of ventilation.

The purpose of this study include (1) To investigate the efficacy of ventilator hyperinflation technique to re-expand lung atelectasis on patients with critical trauma who intubated and mechanical ventilation in the intensive care unit, (2) To investigate the effectiveness of ventilator hyperinflation technique to improve airway clearance on patients with critical trauma in the intensive care unit, and (3) To explore the acute responses of ventilatory functions to ventilator hyperinflation technique on patients with critical trauma who intubated and mechanical ventilation in the intensive care unit.

The aim of this study is to evaluate the effects of the use of breathing exercises with inspiratory loading on respiratory muscle strength and endurance, lung volumes and capacities and thoracoabdominal mobility in patients after bariatric surgery. It is believed that the use of inspiratory load may mitigate the negative effects of surgical trauma on respiratory muscle dysfunction, preserving respiratory muscle strength, lung volumes and diaphragm mobility, thus reducing the risk of pulmonary complications in the postoperative period.

The aim of this study will be to investigate the effects of using physical therapy resources in the postoperative morbidly obese individuals undergoing gastroplasty. It is believed that the application of these various features of physiotherapy after abdominal surgery may contribute differently in restoring lung function and prevention of pulmonary complications and can thus identify the resources that can contribute more effectively in post-operative bariatric surgery.

The investigators hypothesized that dornase alpha, administered twice a day (BID) by in-line nebulizer, would improve oxygenation, compliance, and time to extubation in adult patients receiving mechanical ventilation.

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.
