Filter by:The purpose of this study was to evaluate the curative effect of Levosimendan on ARDS patients through omni-directional and multi-angle objective quantitative indexes, and to study the responsiveness of ARDS with or without right ventricular insufficiency to the treatment of Levosimendan, and to indirectly confirm whether Levosimendan had lung protective mechanism other than calcium sensitization to ARDS patients, such as inhibiting inflammatory reaction to reduce pulmonary capillary leakage and alveolar epithelial cell injury. Relaxation of bronchial smooth muscle improves pulmonary ventilation function. To provide new methods and ideas for clinical treatment of ARDS.
Although mechanical ventilation remains the cornerstone of ARDS treatment, several experimental and clinical studies have undoubtedly demonstrated that it can contribute to high mortality through the developing of ventilator induced lung injury even in patients with plateau pressure <30 cmH2O. Since now there are no studies exploring the application of low flow extracorporeal CO2 removal and ultraprotective ventilation to reduce mechanical power, a composite index of VILI, independently from the value of plateau pressure or the severity of hypercapnia.
The purpose of this study is to assess the effect of different levels of PEEP on the cardiocirculatory system in patients affected by the acute respiratory distress syndrome (ARDS)
The aim of this study is to investigate the use neurally adjusted ventilatory assist (NAVA) as lung protective strategy in patients with acute respiratory distress syndrome (ARDS).
The histologic hallmarks of lung inflammation include accumulation of inflammatory cells in the airspaces and interstitium, injury to alveolar epithelial and endothelial cells, loss of epithelial-capillary integrity and accumulation of edema fluid in the interstitium and airspaces. Accordingly, for alveolar repair to occur inflammation must be halted, debris and inflammatory cells removed, injured tissue cells replaced, and capillary barrier function re-established. Macrophages are key players in all of these. Here the investigators hypothesize that resident alveolar macrophages and recruited macrophages serve completely different functions, acting independently (i.e. division of labor) yet cooperatively (synergism).
To observe the influence of different methods titrating PEEP on right heart function and pulmonary artery pressure in ARDS patients .
Expiratory flow limitation (EFL) is defined as a dynamic condition that expiratory flow cannot be further increased with higher expiratory driving pressure. Under mechanical ventilation, it can cause intrinsic positive end-expiratory pressure (PEEP) and dynamic hyperinflation, and be associated with worse clinical outcome. The detection of EFL however needs special maneuvers and offline analysis of flow-volume curves, which are infeasible in routine practice and cannot be used during real-time monitoring. The investigators propose a new and simple approach using flow derived parameters to detect EFL in real time without needing any intervention.
The goal of this interventional crossover study, in intubated and mechanically ventilated Acute Respiratory Distress Syndrome (ARDS) patients, is to compare two positive end-expiratory pressure (PEEP) titration techniques regarding: respiratory mechanics, gas exchange, changes in aeration, ventilation/perfusion matching its impact on cardiac function, especially the right heart (RH). The PEEP titration techniques are: PEEP selection based on low PEEP/high FiO2 table ("PEEPARDSnet") and lung recruitment maneuver (LRM) plus PEEPdec titration based on the best compliance of the respiratory system("PEEPLRM").
