Filter by:This study aimed to fill this knowledge gap and designed a multicentre cohort study to verify the hypothesis that LUS has good reliability to predict BPD in China and to compare the predictive value of LUS and clinical models for the development of BPD at different time points in infants born before and after 28 weeks.
General anesthesia is characterized by temporary loss of consciousness and decreased reflex activity without any change in vital functions. It can be performed with intravenous and/or inhalation agents. During general anesthesia, breathing is stopped and respiratory support is provided to patients with various respiratory equipment and ventilation modes on the anesthesia device. The most commonly used ventilation modes during anesthesia are volume controlled (VCV) and pressure controlled (PCV). In pressure-controlled ventilation, ventilation is provided with the airway pressure determined by the anesthesiologist throughout inspiration. While the pressure is constant during inspiration, the tidal volume is variable. In volume controlled ventilation, ventilation executed at the volume is set by the anesthesiologist. In other words, the determined volume is constant, but airway pressures vary. In pediatric anesthesia practice modes have not been shown to have a clear advantage over each other. Both modes have advantages and disadvantages. With the development of modern anesthesia devices in recent years, safe ventilation can be provided even in very young children with volume controlled mode (VCV). Atelectasis is the restriction of gas exchange due to complete or partial collapse of the lung. Atelectasis can be seen in 90 percent of patients receiving general anesthesia. This incidence is reported to be 68-100 percent in children. Lung ultrasonography is an imaging method with many advantages for imaging lung-related diseases, such as not containing ionizing radiation, being inexpensive, and being performed at the bedside. Recently, its use by anesthesiologists has become widespread in many lung pathologies, including atelectasis. Traditional and modified lung ultrasonography scoring systems can be used to evaluate atelectasis in lung parenchyma with ultrasonography. In addition to the traditional system, modified scoring system also enables to evaluate small subpleural consolidations In this study, it was aimed to compare the effects of volume controlled and pressure controlled ventilation modes used in general anesthesia in children on atelectasis with lung ultrasonography.
There is an increasing trend in the use of robotic-assisted radical prostatectomy or cystectomy (RARPC). Preventing lung atelectasis without inducing overdistention of the lung is challenging. Many studies tried to optimize PEEP titration by using methods such as dead space fraction guided and static pulmonary compliance directed techniques, or by using electrical impedance tomography. However, the use of these methods is limited by inaccuracy and the need for sophisticated devices. Bedside Lung ultrasound is fast, easy and economic technique that is gaining interest in the operating room. Ultrasound-guided PEEP titration has been used in bariatric surgeries (different position and usually shorter procedure time) and proved effective in improving oxygenation, compliance and reducing the incidence of postoperative pulmonary atelectasis and hypoxia without causing hemodynamic instability. The aim of this study is to evaluate the effectiveness of intraoperative individualized lung ultrasound-guided stepwise PEEP optimization in patients undergoing RARPC on oxygenation, intraoperative and early postoperative pulmonary complications.
Rheumatoid arthritis is an autoimmune disease that can affect various organs, including the lungs, and lead to rheumatoid arthritis-interstitial lung disease (RA-ILD). RA-ILD is responsible for increased mortality in rheumatoid arthristis (RA) patients. The prevalence of RA-ILD varies according to the screening tool used. The current gold standard is chest CT, but this is an expensive, time-consuming and irradiating examination, and recommendations on when and how often it should be performed are not clearly established. Lung ultrasound (LUS) is an emerging tool for the detection of lung parenchymal damage, particularly in systemic scleroderma and idiopathic pulmonary fibrosis (IPF). LUS is a non-irradiating, non-expensive examination that can be performed rapidly. The aim of our study is to evaluate LUS as a screening tool for RA-ILD, in patients with risk factors for developing RA-ILD.
There is no a reliable marker of intraoperative fluid excess or overload. The use of lung ultrasound in other settings, such as emergency room and critical care patients, helps us to determine if a patient has a condition of augmented intrathoracic fluid, that could be related to several circumstances, such as fluid overload, but also to heart failure, in example. Nevertheless, there is no information regarding the basal incidence of this finding, to ascertain if could be eventually used as a potential marker of fluid overload. This protocol looks for the incidence of the finding of B-Lines, which are related to fluid overload, in patients undergoing open abdominal surgery.
The goal of this observational study is to learn about the function of lung and diaphragm ultrasound during weaning from mechanical ventilation in COVID-19 patients. The aim of this study was that the lung ultrasound score and diaphragm muscle mobility could be a potential predictive factor of weaning success.
Rationale Acute respiratory distress syndrome (ARDS) is a frequent cause of hypoxemic respiratory failure with a mortality rate of approximately 30%. The identification of ARDS phenotypes, based on focal or non-focal lung morphology, can be helpful to better target mechanical ventilation strategies of individual patients. Lung ultrasound (LUS) is a non-invasive tool that can accurately distinguish 'focal' from 'non-focal' lung morphology. The investigators hypothesize that LUS-guided personalized mechanical ventilation in ARDS patients will lead to a reduction in 90-day mortality compared to conventional mechanical ventilation.
The formalized expert recommendation of the French Society of Anesthesia and Intensive Care recommends guiding vascular filling by measuring the stroke volume (SV) in surgical patients considered at high risk. Vascular filling should be continued in the event of preload dependence and stopped in the event of the appearance of preload independence. The aim is to avoid vascular overload due to excessive vascular filling. The application of this recommendation has resulted in a reduction in postoperative morbidity, length of hospital stay and time to return to oral feeding. The superiority of this strategy is now being questioned and the predictive indices of response to vascular filling (static and dynamic) have many limitations. In addition, none of the cardiac output monitors are the gold standard for intraoperative use. Through the study of artefacts, lung ultrasound has been gaining ground over the last twenty years, particularly in cardiology, nephrology and intensive care. By analogy with radiological B-lines, ultrasound B-lines result from the reverberation of ultrasound on the subpleural inter-lobular septa thickened by oedema. The Fluid Administration Limited by Lung Sonography (FALLS) protocol, described by Lichtenstein et al, is defined as the visualisation of new B lines during a vascular filling test. If a B-line appears in an area where it was not present during vascular filling, the most likely diagnosis is hydrostatic overload of the subpleural interstitial septum. This appearance of B-lines occurs at a sub-clinical stage. The use of lung ultrasound could allow real-time assessment of vascular filling and its tolerance during the intraoperative period. The main objective of the study is to demonstrate a decrease in the incidence of postoperative complications (organ failure) (as defined by international guidelines) when using lung ultrasound-guided haemodynamic optimisation compared to standard optimisation.
This study aims to compare the accuracy of the total thoracic fluid content (TFC) measured by electrical cardiometry with accuracy of lung ultrasound score in prediction of weaning outcome in mechanically ventilated patients.
The main purpose of the study is to compare the effectiveness of PEEP application in terms of perioperative oxygenation level in the use of classical LMA and i-gel, which is often preferred. The secondary aim is to compare parameters such as gastric insufflation and the rate of postoperative pulmonary complication development in the case of PEEP with two supraglottic airway devices.
