Filter by:A new artificial lung device has been developed that potentially provides added support to mechanical ventilation for severely damaged lungs. The Hattler Respiratory Assist Catheter is designed to provide gas exchange (deliver oxygen and remove carbon dioxide) for a period of up to 7 days, providing more time for the lungs to improve. Extrapolating from large animal data, the hypothesis is that the Hattler Catheter will be capable of providing 30% to 40% of the basal requirements of carbon dioxide exchange in a manner that is dependable and reproducible.
The investigators aim to study the effect of different levels of PEEP in ALI/ARDS patients on gas exchange.
To assess rapidly innovative treatment methods in patients with adult respiratory distress syndrome as well as those at risk of developing ARDS.
The aim of this study is to evaluate the effects in terms of gas exchange, respiratory mechanics and comfort of breathing, of different assisted mechanical ventilation in ALI/ARDS patients.
Acute Respiratory Distress Syndrom is associated to lung and systemic inflammation, which could be worsened by mechanical ventilation.This included a proteasis - antiproteasis imbalance which could participate to a fibrosis process. Low tidal-volume ventilation (6 mL/kg) with low plateau pressure (< 30 cm H2O) has been proved to decrease mortality when compared with more conventionnal high-volume (12 mL/kg) ventilation.Moreover, this lung-protective approach decrease lung annd systemic inflammation. Using recruitment maneuvers (i.e. the application during a short time of high pressures with the intention to re-open the lung, followed by an increase of PEEP-level to keep the lung open, in an attempt to decrease the alveolar shear-stress) has been proposed to improve oxygen and to reduce bio-trauma. However, the effect of such maneuvers on the inflammatory response and on the evolution of ARDS remains unknown. Therefore we have planned a randomized, monocentric, controlled trial consisting of the comparison of two approaches of mechanical ventilation in Acute Lung Injury. This trial will include 30 hemodynamically stable patients fulfilling the ALI or ARDS criteria defined by the US and European Consensus Conference. They will be randomized in two groups: standard low-volume ventilation vs. recruitment maneuvers. The main objective of our study is to compare both ventilatory strategies in termes of lung and systemic inflammation. The primary outcome measures will be the proteasis activity as measured in broncho alveolar fluid (BAL) and pro- and antiinflammatory cytokines activity as measured in the BAL and in the blood. Two samples (BAL and blood) will be obtained at a 48-72 hours interval. In the recruitment maneuver group, the first BAL will be obtained two hours before the maneuver. Secondary outcome measures will be gaz exchange, respiratory mechanics, systemic hemodynamics and visceral dysfunction scores.
The investigators aim to compare the respiratory mechanics in acute lung injury (ALI)/acute respiratory diseases syndrome (ARDS) patients with and without pleural effusion.
This research project is an open-label, randomized study for the use of Nitric Oxide in pediatric patients with acute respiratory distress syndrome (ARDS). The study examines whether nitric oxide (NO) treatment impacts the the P:F ratio (arterial partial pressure of oxygen (PaO2) divided by fraction of inspired oxygen (FiO2) in patients with ARDS. The goal of the study is to evaluate whether the order of NO therapy will have any effect on response, and evaluate the characteristics of patients who respond to NO compared to those who do not.
The objective of this study is to analyze by trans-oesophageal echocardiography the effect on the right ventricle of positive expiratory pressure (PEP) level variations with constant plate pressure among patients with syndrome of acute respiratory distress of the adult (SDRA). The assumption tested is that a high level of PEP increases the impedance with the ejection of the right ventricle independently of the level of plate pressure. The effect on the right ventricular preload will be checked via the analysis of the respiratory variability of the diameter of the higher vena cava.
Study of the long term outcomes and economic impact of the pulmonary artery catheter in acute respiratory distress syndrome (ARDS/ALI) patients.
This is a phase II, randomized, double-blind, placebo-controlled, safety and efficacy study of a recombinant chimeric monoclonal antibody against CD14 (IC14) in hospitalized patients with acute lung injury (ALI).
