Filter by:Acute respiratory distress syndrome (ARDS) in neonates has been defined in 2017.The death rate is over 50%. HFOV and CMV are two main invasive ventilation strategies. However, which one is better needing to be further elucidated.
Acute Respiratory Distress Syndrome (ARDS) is a serious condition that occurs as a complication of medical and surgical diseases, has a mortality of ~40%, and has no known treatment other than optimization of support. Data from basic research, animal models, and retrospective studies, case series, and small prospective studies suggest that therapeutic hypothermia (TH) similar to that used for cardiac arrest may be lung protective in patients with ARDS; however, shivering is a major complication of TH, often requiring paralysis with neuromuscular blocking agents (NMBA) to control. Since the recently completed NHLBI PETAL ROSE trial showed that NMBA had no effect (good or bad) in patients with moderate to severe ARDS, the investigators sought to evaluate whether TH combined with NMBA is beneficial in patients with ARDS. The investigators are scheduled to begin enrolling in a Department of Defense-funded Phase IIb multicenter RCT of TH (core temperature 34-35°C) + NMBA for 48h vs. usual temperature management in patients with ARDS with time on ventilator as the primary outcome. Since COVID-19 is now the most common cause of ARDS, we are conducting a pilot study to examine the safety and feasibility of including patients with COVID-19-associated ARDS in our upcoming trial. In this pilot, we will randomize 20 patients with COVID-19 and ARDS to either TH+NMBA for 48h or usual temperature management. The primary outcome is achieving and maintaining the target temperature. Secondary outcomes include safety, physiologic measures, mortality, hospital and ICU length of stay, and serum biomarkers collected on days 0, 1, 2, 3, 4, and 7.
We would study whether there is any measurable benefit of the administration of nebulized n-acetyl-cysteine to acute respiratory distress syndrome patients starting within 48 hours of intubation and mechanical ventilation.
ROSETTA is a multi-centre study evaluating the time course of diaphragm thickness and function following exposure to neuromuscular blockade or control in patients with acute respiratory distress. ROSETTA is an ancillary study to the Re-evaluation of Systemic Early Neuromuscular Blockade (ROSE) trial (NCT02509078). It is designed to (1) test the feasibility of a multi-center evaluation of the diaphragm structure and function by ultrasound during mechanical ventilation and (2) determine whether neuromuscular blockade accelerates atrophy and dysfunction of the diaphragm in patients with acute respiratory distress syndrome (ARDS).
The primary objective of this study is to evaluate whether a multi-component implementation strategy/quality improvement intervention comprised of 1) clinical decision support that couples a natural language processing (NLP) acute respiratory distress syndrome (ARDS) recognition tool with a clinician alert system, and 2) audit and feedback improves the implementation of low tidal volume ventilation (LTVV) for patients with the acute respiratory distress syndrome (ARDS). This will be accomplished with a cluster randomized controlled trial comparing the implementation strategy to usual care
Acute Respiratory Distress Syndrome (ARDS) patients will be randomized to receive either IC14 (a single dose of 4 mg/kg followed by 2 mg/kg on Days 2-4) or placebo. Study participation will be for a total of 28 days.
The acute respiratory distress syndrome (ARDS) is common condition in critical ill patients affecting 7.2 people / 100,000 population / year and more than 7% of patients with invasive mechanical ventilation for more than 24 hours. ARDS carries a high hospital mortality of up to 48% and consumes large amounts of critical care resources. ARDS patients often present with severe hypoxemia that is refractory to conventional treatment and are thus evaluated for extracorporeal membrane oxygenation (ECMO). However, uncertainty regarding the appropriate indication for ECMO and clinical evidence for ECMO as a rescue treatment are still controversial. In 2012 Grasso and colleagues therefore presented a case series of influenza A (H1N1) ARDS patients describing the use of esophageal pressure measurements for individualized PEEP titration to achieve an end expiratory plateau pressure of the lung (PPLATL) of 25cm H2O. After performing the measurements in 14 patients, ventilator settings could be adjusted in half of these patients by increasing PEEP which resulted in an increase of oxygenation measures to an extend that criteria for extracorporeal support where no longer met and conventional treatment with invasive mechanical ventilation could be continued. However, uncertainty remains as to whether these results are generalizable to ARDS of any cause. In addition, increasing PEEP might impact on cardiac function and might therefore be associated with clinical important hemodynamic effects in these patients. The investigators aim to evaluate hemodynamic changes in patients with severe ARDS in which an individualized PEEP treatment strategy can be employed. ARDS will be defined and stratified according to the Berlin ARDS definition. A naso-gastric probe capable of measuring esophageal pressure will be inserted directly after admission to the ICU as previously described. Invasive mechanical ventilation and oesophageal pressure measurements will be done using the GE Healthcare Carescape R860 ventilator. A pulmonary artery catheters (Edwards CCOcomb) will be inserted to evaluate the hemodynamic parameters of cardiac output, pulmonary artery pressures and left atrial pressures. Volumetric parameters will be measured using tanspulmonary thermodilution devices (Edwards EV1000). Cardiac function will be addressed in addition by the use of a predefined echocardiography protocol.
This study will investigate the safety and efficacy of the administration of inhaled GM-CSF to patients with respiratory virus-associated pneumonia.
Lung units that participate in gas exchange are known as 'recruited' lung. Patients with lung injury suffer from a proportion of units that do not participate in gas exchange (i.e. the derecruited lung), which results in impaired gas exchange and induces an inflammatory cascade. The level of PEEP is often coupled to indices of oxygenation such as PaO2, PaO2 to FIO2 ratio, or oxygen index. Currently, two strategies are widely accepted and considered equivocal, one strategy using a lower PEEP level coupled to a certain oxygen requirement, the other using a higher PEEP level. The primary purpose of this study is to demonstrate the safety and efficacy of an electrical impedance tomography (EIT) PEEP titration protocol designed to recruit collapsed lung in children with ARDS and properly maintain lung volumes by setting an optimal PEEP level. A safety system has been developed using the ARDSnet FIO2/PEEP High (upper threshold limit) and Low (lower threshold limit) algorithm. Efficacy will be defined as an improvement in lung volume as assessed by electrical impedance tomography, lung compliance and by an improvement in markers of gas exchange. Safety will be defined as the incidence of barotrauma and hemodynamic consequences that occur during the protocol. Those results will be compared to incidences of barotrauma and hemodynamic compromise within the ARDS literature. Knowledge gained from this pilot will be instrumental in developing an EIT imagine guided protocol which will allow us to conduct future RCTs utilizing EIT technology
This is a multicenter randomized controlled pilot trial to investigate the feasibility of a driving pressure limited mechanical ventilation strategy compared to a conventional strategy in patients without acute respiratory distress syndrome (ARDS).
