Filter by:The purpose of the present study is to visualize the inflammatory response and coagulation disorders during cardiac surgery in order to identify possible predictors for acute lung injury postoperatively.
This is a randomized, double-blind, placebo-controlled, single ascending (SAD), and multiple ascending dose (MAD) study conducted at a single clinical site within the UK. Healthy male and female subjects (on non-child bearing potential) will be enrolled to investigate single inhaled doses of molgramostim at 3 dose levels (Part 1) and multiple inhaled doses at 2 dose levels (Part 2). The 2 doses in the multiple ascending dose regimens will be administered once daily (QD) for 6 consecutive days. The clinical indication for inhaled molgramostim is the treatment of respiratory diseases such as aPAP, bronchiectasis and cystic fibrosis. The Clinical trial will involve 42 healthy participants. The trial is expected to last approximately 4 months.
This is a proof of concept study where the investigators aim to study the correlation between the use of a simple bedside ultrasound measurement of diaphragmatic muscle excursion with established (but time consuming) measurements made to optimize an important setting on the mechanical ventilator (positive end expiratory pressure or PEEP) in intubated adults with acute respiratory distress syndrome (ARDS) in the medical ICU.
This study will test the validity of a new approach to assess alveolar recruitability at the bedside in comparison to direct measurements of lung volume and derecruitment.
This study is designed to compare three ultrasound-based aeration scores that were previously validated in specific populations, and to assess their correlation with computed tomographic measurement of pulmonary aeration in a population with different pathologies. Hypothesis: The "Loss of Aeration Score" will be more accurate than a simplified version and another widely used score, the "Lung Ultrasound Score".
Extracorporeal membrane oxygenation (ECMO) has been widely used in patients with severe acute respiratory distress syndrome (ARDS). But how to choose mechanical ventilation strategy is still not clear for severe ARDS patients supported by ECMO. Our previous work found that, compared to the traditional "lung rest" strategy, transpulmonary pressure guide new lung ventilation strategy can better maintain lung volume reduction lung collapse, atelectasis occurs. The severe ARDS patients receiving ECMO therapy were randomized divided into a new ventilation strategy group and the conventional ventilation strategy group. The new ventilation strategy is transpulmonary pressure guide ventilator setting method, and the conventional ventilation strategy is Extracorporeal Life Support Organization (ELSO) guide ventilation method. Compare the difference between the two groups of patients in lung injury, and explore the lung protection mechanism of new lung ventilation strategies guided by transpulmonary pressure. Our research group considered that transpulmonary pressure guide new lung ventilation strategy can provide more effective lung protection. And it will be further used in clinical work.
The purpose of this study is to assess the safety of inhaled carbon monoxide (iCO) in intubated patients with sepsis-induced ARDS.
Adequate PEEP selection in ARDS is still a matter of research. The main objectives of using PEEP in ARDS are improvement in oxygenation, lung recruitment at the end of expiration, prevention of opening and closing of terminal respiratory units at minimal hemodynamic compromise. The challenge is to carry out these objectives in a patient-centered approach based on individual characteristic of lung pathophysiology. Recently, it has been proposed to set PEEP from the trans-pulmonary end-expiratory pressure. Trans-pulmonary pressure (Ptp) is obtained from the difference between airway pressure and measured esophageal pressure (Pes). Measured Pes values have been found positive in the supine position in ARDS patients, leading to negative values of Ptp. The strategy proposed by Talmor and coworkers is to adjust PEEP up to get Ptp between 0 and 10 cm H2O. Whether this strategy improves survival is under investigation. Prone position ventilation significantly improves survival in severe ARDS as demonstrated by meta-analyses and a recent multicenter randomized controlled trial. The purpose of present project is to investigate Ptp at end-expiration in the prone position in severe ARDS. The project is centered on the question about what are the values of measured Pes in prone position. The hypothesis is that they are lower than in the supine position due to the relief of the weight of heart, mediastinum and lung and also to recruitment of dorsal lung regions. To investigate this hypothesis, measured Pes, Ptp, end-expiratory lung volume, overall lung recruitment (pressure-volume curve), and regional recruitment by using electrical impedance tomography. will be assessed in supine then in the prone position across two different strategies of PEEP selection, PEEP/FIO2 table and Talmor proposal.
Hypoxemia may be refractory to protective ventilation during the acute respiratory distress syndrome (ARDS), justifying the use of other therapies that improved oxygenation and decreased mortality, including prone position (PP). During ARDS, the majority of patients are responders to PP with increased PaO2 due to homogenization of the ventilation-perfusion ratio. Despite changes in intra-thoracic and intra-abdominal pressure, hemodynamic parameters are not changed. Besides the fact that the PP improves systemic oxygenation is it the same on cerebral oxygenation? No study has investigated the cerebral oxygenation during PP in patients with ARDS. The cerebral oxygenation may be altered due to the position of the patient and high levels of positive end-expiratory pressure. This decrease oxygenation may be responsible for cognitive impairment when patients awake. NIRS (Near Infrared Spectroscopy) is a noninvasive tool, capable of delivering information on cerebral oxidative metabolism and its hemodynamic status. It can be used routinely for the management of resuscitation in Intensive Care Unit (ICU) patients. This study is to investigate cerebral oxygenation during prone position in the investigators' patients of ICU.
The purpose of this study was to evaluate the availability and diagnostic accuracy of point-of-care bedside lung ultrasound examination in management of mechanical ventilation in neonatal acute respiratory distress syndrome.
