Active clinical trials for "Respiratory Distress Syndrome"

This is an open-label run-in followed by a randomized, double-blind drug treatment study of COVID-19 infected patients requiring inpatient hospital admission.

Implement surfactant (BLES®) replacement therapy using the Less Invasive Surfactant Administration technique in six tertiary institutions in Nigeria and evaluate its impact on 72-hour neonatal mortality in premature infants born less than 2000 grams at birth.

This study is a multicentric randomized controlled study.The objective of this study is to compare the prognosis of patients with ARDS between EIT-oriented individualized PEEP and traditional lower PEEP/FiO2 table-oriented PEEP strategy.

Acute respiratory distress syndrome (ARDS) in neonates has been defined in 2017. The death rate is over 50%.There are no special treatments for acute respiratory distress syndrome.

Severe hypoxemia following trauma may happen in many circumstances (aspiration, ventilation-associated pneumonia, lung contusion...), most of which are not exclusively associated with a direct injury to the lungs. Severe trauma and associated musculoskeletal injuries result in the acute release of Damage-Associated Molecular Patterns (DAMPs) in plasma, many of which are made of nucleic acids. DAMPs then bind leukocytes and trigger NETosis (Neutrophil Extracellular Traps), the release of nuclear material coated with proteolytic enzymes, which ultimately promotes remote lung injury and acute respiratory distress syndrome (ARDS). Considering that many DAMPs and all NETs are made of nucleic acids, we hypothesize that dornase alfa, a commercially available recombinant desoxyribonuclease (DNAse) could reduce DAMPs and NETs-induced lung injury in severe trauma patients under mechanical ventilation in the intensive care unit (ICU). The primary objective is to demonstrate a reduction in the incidence of moderate to severe ARDS in severe trauma patients during the first seven ICU days from 45% to 30% by providing aerosolized dornase alfa once during the first two consecutive ICU days and compared to equivalent provision of placebo (NaCl 0,9%). The secondary objectives are to demonstrate, by using aerosolized dornase alfa compared to placebo: an improvement in static lung compliance a reduction in mechanical ventilation duration / an increase in ventilation-free ICU days a reduction in the length of ICU stay a reduction in the hospital length of stay a reduction in multi-organ failure a reduction in ventilator-associated pneumonia (VAP) a reduction in mortality at day 28

International guidelines recommend giving positive pressure ventilation (PPV) by face mask to newborns who do not breathe or have a slow heart rate at birth. Preterm infants are at high risk of developing respiratory distress syndrome (RDS) and many are treated with continuous positive airway pressure (CPAP) in the neonatal intensive care unit (NICU). Though the majority of preterm infants breathe spontaneously at birth, many clinicians routinely apply a face mask to preterm infants shortly after birth in the delivery room (DR) to give them CPAP. However, applying a face mask may inhibit spontaneous breathing in newborns. In this study, premature babies will be randomly assigned to have a face mask routinely applied for CPAP shortly after birth; or to have a face mask selectively applied only for PPV if they are not breathing or have a slow heart beat in the first 5 minutes of life, or for CPAP if they have signs of respiratory distress after 5 minutes. The investigators will determine whether fewer participants who have the mask selectively applied receive PPV in the DR.

This is a prospective, observational cohort study. For the study part on noninvasive neurally adjusted ventilatory assist (NIV-NAVA) the design is interventional. For all participants prospective data collection will be conducted by chart review and by downloading ventilatory data from the ventilator. A registration of respiratory severity score will be done by a caregiver during the weaning period. This consists of a visual assessment of the work of breathing every 2 hours. For participants on NIV-NAVA consenting to the interventional part of the study a titration procedure will be conducted, afterwards serial electrical impedance tomography and lung and diaphragm ultrasound measurements will be done.

Treatment of acute respiratory distress syndrome (ARDS) relies on invasive mechanical ventilation with supposedly protective settings (low tidal volume ventilation). Mortality of ARDS remains high in observational studies (40 to 50%). Approximately 30% of ARDS patients exhibit tidal hyperinflation despite low tidal volume ventilation, suggesting that personalization of tidal volume is required to improve ARDS prognostic. To date, reliable bedside tools to adjust tidal volume are lacking. Excessive tidal volume can be detected using computed tomography by quantification of tidal hyperinflation, but this technique is reserved to research studies and requires patient transport to imaging facility. Mechanical ventilation generates cardio-pulmonary interaction, whose magnitude is influenced by tidal volume and respiratory system characteristics. Pulse pressure variation is a bedside tool with potential to quantify cardio-pulmonary interactions. Increasing tidal volume will decrease right ventricular preload and increase right ventricular afterload, hence maximizing cardio-pulmonary interactions. The investigators hypothesize that pulse pressure variation might help to detect excessive tidal volume during a tidal volume challenge (i.e. stepwise increase in tidal volume)

Right ventricular failure may be associated with mortality in patients with acute respiratory distress syndrome (ARDS). Mechanical ventilation may promote right ventricular failure by inducing alveolar overdistention and atelectasis. Electrical impedance tomography (EIT) is a bedside non-invasive technique assessing the regional distribution of lung ventilation, thus helping titrating positive end-expiratory pressure (PEEP) to target the minimum levels of alveolar overdistension and atelectasis. The aim of this physiologic randomized crossover trial is to assess right ventricular size and function with transthoracic echocardiography with different levels of PEEP in adult patients with moderate-to-severe ARDS undergoing controlled invasive mechanical ventilation: the level of PEEP determined according to the ARDS Network low PEEP-FiO2 table, the PEEP value that minimizes the risk of alveolar overdistension and atelectasis (as determined by EIT), the highest PEEP value minimizing the risk of alveolar overdistension (as determined by EIT), and the lowest PEEP level that minimizes the risk of alveolar atelectasis (as determined by EIT). Our findings may offer valuable insights into the level of PEEP favoring right ventricular protection during mechanical ventilation in patients with ARDS.

The objective of this study was to investigate the hemodynamic effects of two alveolar recruitment maneuver strategies in critical care patients with acute respiratory distress syndrome.
