Filter by: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.
This study has been added as a sub study to the Simulation Training for Emergency Department Imaging 2 study (ClinicalTrials.gov ID NCT05427838). The Lunit INSIGHT CXR is a validation study that aims to assess the utility of an Artificial Intelligence-based (AI) chest X-ray (CXR) interpretation tool in assisting the diagnostic accuracy, speed, and confidence of a varied group of healthcare professionals. The study will be conducted using 500 retrospectively collected inpatient and emergency department CXRs from two United Kingdom (UK) hospital trusts. Two fellowship trained thoracic radiologists will independently review all studies to establish the ground truth reference standard. The Lunit INSIGHT CXR tool will be used to analyze each CXR, and its performance will be measured against the expert readers. The study will evaluate the utility of the algorithm in improving reader accuracy and confidence as measured by sensitivity, specificity, positive predictive value, and negative predictive value. The study will measure the performance of the algorithm against ten abnormal findings, including pulmonary nodules/mass, consolidation, pneumothorax, atelectasis, calcification, cardiomegaly, fibrosis, mediastinal widening, pleural effusion, and pneumoperitoneum. The study will involve readers from various clinical professional groups with and without the assistance of Lunit INSIGHT CXR. The study will provide evidence on the impact of AI algorithms in assisting healthcare professionals such as emergency medicine and general medicine physicians who regularly review images in their daily practice.
1. Oxygenation index and bedside ultrasound would be used to evaluate the therapeutic effect of novel recruitment maneuver therapy in the patients with pulmonary atelectasis after cardiac surgery. 2. To establish a new therapy strategy for pulmonary atelectasis after cardiac surgery and to evaluate its effectiveness and safety for the cardiac patients complicated with postoperative pulmonary atelectasis.
Video-assisted thoracic surgery (VATS) is usually performed with general anesthesia and single lung ventilation. However, performing thoracic surgery under awake regional anesthesia has several potential advantages including avoidance of airway trauma and ventilator dependence associated with endotracheal intubation, besides promoting enhanced recovery after surgery and shorter mean hospital stay.
Evaluate the effects of high-flow nasal oxygen therapy on atelectasis in the perioperative period by lung ultrasound (LUS) in bariatric surgery patients.
The study comprises two different objectives. Longitudinal description of postoperative pulmonary dysfunction in the cardiothoracic surgery patient, and the comparison of two different lungrecruitment strategies.
The goal of this interventional crossover study in morbidly obese intubated and mechanically ventilated patients is to describe the respiratory mechanics and the heart-lung interaction at titrated positive end-expiratory pressure levels following a recruitment maneuver with transthoracic echocardiography and electric impedance tomography imaging.
Atelectases (collapsed lung areas) of 15-20% of total lung occur in up to 90% of patients who are anaesthetized and intubated. The goal of the present prospective study is to detect atelectatic areas in the perioperative period in the lungs of patients undergoing elective laparoscopic surgery non-invasively and without x-ray exposure. Results of lung ultrasound (LUS) as the experimental method will be compared to the results of Electrical Impedance Tomography (EIT) as the reference technique for the detection of atelectasis. A device for peripheral Oxygen saturation measurement (MASIMO Radical-8) will detect changes in ventilation. The investigators want to confirm or disprove former findings of the appearance of intraoperative atelectases and to prove that ultrasound is a valid tool for detection of atelectases.
