Filter by:Given the scarcity of studies aimed at assessing the effect of anesthesia and m ventilation on the distribution of lung ventilation in pediatric patients undergoing surgery, with the exclusion of thoracic surgery, the present prospective observational study would shed the light on ventilation practice in pediatric anesthesia for surgery. This study wold fill the actual gap allowing the evaluation, through electrical impedance tomography (EIT) of the distribution of lung ventilation across the different phases of anesthesia for pediatric surgery. These insights could contribute to improve clinical practice and research in the management of ventilation in pediatric patients undergoing anesthesia for surgery.
The study, named as "The Efficacy of Driving Pressure-guided Lung Protective Ventilation in Surgical Repair of Acute Type A Aortic Dissection: an open-label, randomized control clinical trial", aims to investigate whether driving pressure-guided lung protective ventilation can reduce postoperative oxygenation function in patients who have undergone surgical repair of acute type A aortic dissection. The primary outcomes is the incidence of postoperative hypoxemia (a partial pressure of arterial oxygen to inspiratory oxygen fraction ratio less than 300 mm Hg or a peripheral blood oxygen saturation less than 93% at any concentration of inspiratory oxygen) within 7 days after the surgery.
This is an investigator-initiated, international, multicenter, prospective, cross-sectional study that aims to 1) describe the incidence and types of postoperative pulmonary complications (PPCs), 2) describe patient demographics, baseline characteristics, and intraoperative ventilation management, 3) describe the occurrence of intraoperative adverse events (IAEs), and 4) their associations with PPCs, 5) assess the practice of intraoperative mechanical ventilation. Patients will be eligible for participation if: 1) adult and 2) receiving intraoperative ventilation during general anesthesia for surgery. Patients receiving ventilation outside of an operating room as well as patients receiving intraoperative ventilation during extracorporeal life support will be excluded
The goal of this study is to compare two continuous positive airway pressure (CPAP) settings on heart and lung function in patients with severe obesity after anesthesia. The main questions it aims to answer are: 1. Does a recruitment maneuver and CPAP set to intrathoracic pressure (ITP) improve cardiopulmonary function compared to standard CPAP settings in patients with severe obesity after anesthesia? 2. Does the location of adipose tissue influence the response to CPAP settings in patients with severe obesity after anesthesia? Participants will undergo monitoring of their intrathoracic pressure using an esophageal catheter. In the recovery area after anesthesia, participants will receive two CPAP settings, each for 20 minutes. - Intervention 1: Recruitment maneuver and CPAP will set to the level of intrathoracic pressure - Intervention 2: CPAP set to home settings (if OSA is present) or between 8-10 cmH20 (if OSA is not present).
Copeptin serves as a biomarker emanating from the pituitary gland, functioning as the precursor to arginine vasopressin (AVP). Its role in the regulation of endothelial dysfunction, inflammation, and water-electrolyte balance has been established. The measurement of AVP levels poses challenges due to its brief half-life and the intricate nature of its detection method. In contrast, copeptin provides an indirect means of gauging circulating AVP levels, as it can be conveniently assessed through a sandwich immunoassay. As a neuroendocrine stress hormone, copeptin emerges as a prognostic indicator, reflective of an individual's stress burden. Moreover, its applicability extends to various acute conditions such as ischemic stroke or myocardial infarction. Notably, copeptin proves to be a dependable tool in the differential diagnosis of diverse ailments characterized by polyuria and polydipsia. Lower respiratory tract infection (LRTI) stands as the predominant cause of morbidity and mortality among children and adolescents globally. Notably, copeptin has demonstrated utility in forecasting the severity and complications associated with severe pneumonia in adults. While early investigations into copeptin's role in pediatric LRTI suggest its potential for diagnosing pneumonia and predicting complications, the outcomes of these studies present conflicting results. Although there has been a notable increase in studies on copeptin in pediatric patients over the past decade, research specifically exploring its correlation with pneumonia remains scarce. This prospective case-control study is designed to investigate the potential association between copeptin levels and the severity of illness in pediatric patients with pneumonia. The study aims to determine whether copeptin levels can serve as a reliable predictor of disease severity in pneumonia, offering valuable insights for clinical application. The outcomes of this research may contribute significantly to our comprehension of copeptin's role in disease prognosis and management, thereby facilitating the development of more efficacious diagnostic and therapeutic approaches. Additionally, the study seeks to identify the factors influencing copeptin levels and establish a cut-off value for copeptin in pediatric patients diagnosed with pneumonia.
'POStoperative INTELLiVENT-adaptive support VEntilation in cardiac surgery patients II (POSITiVE II) is an investigator-initiated, international, multicenter, parallel, randomized clinical trial in patients after cardiac surgery.
Patients presenting to the emergency department (ED) may require breathing support with machines depending on the condition. Throughout the breathing support, the settings on the breathing machines will be tailored to the patient's requirements. These settings are manually adjusted by trained physicians. Currently, there are machines which can automatically change the settings based on real-time specific information obtained from the patient. This study aims to compare the use of machines which require manual adjustments (open-loop conventional ventilators) and machines which can automatically change the settings (closed-loop automated ventilators). Patients will be carefully selected to ensure no harm is caused whilst delivering the best care. This study will look into the duration when patients are receiving optimum settings and levels of oxygen and carbon dioxide in the blood. The outcomes of this study would allow us to identify methods to improve patient care.
In Denmark, life-dependent home-mechanical ventilation (HMV) is given under the surveillance of a specifically trained respiratory patient caregiver (tPCG). The HMV can be invasive through a tracheostomy or non-invasive via a mask. The purpose of this study is to uncover experiences and challenges associated with having a trained respiratory patient care giver (tPCG) to surveil home-mechanical ventilation (HMV) from the perspective of the patients and their families and to gather information about the expirence of working in a home as a tPCG
This study will explore the potential benefits of sodium-glucose cotransporter 2 (SGLT2) inhibitors in preventing cardiac ischemia and cardiopulmonary edema in patients with acute decompensated heart failure during weaning from ventilators.
The goal of this clinical trial is to compare flow-controlled ventilation (FCV) and pressure-controlled ventilation (PCV) in patients with moderate to severe acute respiratory distress syndrome on the intensive care unit. The main questions it aims to answer are: - Is the mechanical power during flow-controlled ventilation lower than during pressure-controlled ventilation - To gain more understanding about other physiological effects and potential benefits of flow-controlled ventilation in comparison to pressure-controlled ventilation (o.a. the end-expiratory lung volume and homogeneity of ventilation). Participants will be randomized between two ventilation mode sequences, being 90 minutes of FCV followed by 90 minutes of PCV or vice versa.
