Active clinical trials for "Respiratory Distress Syndrome"

To evaluate the use of Life2000® Ventilator, a novel proportional open ventilation system in critical care use of acute onset of respiratory failure (ARF) and mild to moderate forms of acute respiratory distress syndrome (ARDS) in COVID-19 patients and its ability to provide effective ventilatory benefits and or delay patients from progressing to more aggressive forms of invasive mechanical ventilation (IMV).

Considering the potential of mesenchymal stromal cells (MSCs) in the treatment of lung injuries by COVID-19, this pilot clinical trial evaluates the safety and potential efficacy of the cell therapy, administered intravenously, in patients with pneumonia associated with COVID-19-associated acute respiratory distress syndrome.

PEEP titration is a recommended during invasive mechanical ventilation of ICU patients. However, little is known about the right way to conduct this titration. PEEP titration can be conducted by a stepwise increase in PEEP level, or following an ARM and a consecutive stepwise decrease in PEEP level. Those 2 methods will be explored in intubated ICU patients either with healthy lung or ARDS lungs. Physiological exploration will include end-expiratory lung volume measurements, driving pressure, compliance and electro-impedance tomography at each PEEP level.

There is a reducing incidence of pneumothorax, PIE and the combined outcome of death or BPD since the development of Surfactant therapy. A policy of intubation with surfactant administration and mechanical ventilation has become a standard therapy of infants at high risk of RDS. However, initial stabilization with CPAP and, if necessary, given rescue surfactant therapy has remained the standard therapy for preterm infants. Evidence reveals similar results with regard to mortality and neonatal morbidity between the above two strategies. The investigators intend to develop a method of minimally invasive surfactant therapy followed by early CPAP (MISTCPAP) in preterm Infants with high risk of RDS for improving the outcomes and reducing the incidence of BPD.

The objective of this study is to determine whether use of the spontaneous breathing trial allows for earlier successful extubation of very low birth weight (VLBW) infants who are intubated for >48 hours and have not yet been successfully extubated (extubated >7 days).

Goal of the study: To show that prehospital NPPV use for COPD decompensation, as compared to only standard medical treatment, might enable a decrease in intubation rate. Primary end point: the rate of endotracheal intubation in the first three hours after randomization. Secondary en points: rate of endotracheal intubation after third hour, rate of prehospital and ICU mortality, ICU days, effects on clinical parameters (respiratory rate, SpO2, heart rate, arterial blood pressure, consciousness) and arterial blood gases (pH, PaCO2, PaO2), 30 days mortality, delays between first medical contact and in-hospital admission, relation between initial pH level and endotracheal intubation. Inclusion criteria: Adult patients (>18 years), with GCS≥10, known or suspected COPD and presenting acute respiratory decompensation with respiratory acidosis. Exclusion criteria: Cardiac or respiratory arrest, upper gastro intestinal tract haemorrhage, shock, serious ventricular arrhythmia, severe sepsis, multiple organ failure, serious cranial-facial trauma, upper airways obstruction, undrained pneumothorax, uncooperative-agitated patients refusing the technique, respiratory distress with bradypnoea < 12/min, pauses gasps repeated bradycardia, intractable vomiting, acute traumatic tetraplegia, persistant hemodynamic instability with PAS<90mmHg, ensuitable environment. Randomization: Assignment to NPPV group or standard therapy group will be performed at the time of arrival of the SAMU team to the patient, by calling a physician located at the calldispatch center who will connect to the web site of the clinical research unit from Bordeaux university hospital. Period of study: 25 months (24 months for patients inclusion and 1 month for follow-up). Number of patients: 199 patients in each group i.e 398 patients (significance level of 5%, power of 80%; 50% expected decrease of intubation rate, i.e. from 20 to 10%). Main investigator: Dr Pierre-Arnaud Fort, MD, Pôle Urgences-SAMU47-Réanimation, Centre Hospitalier Saint-Esprit - Agen. Participating centers : 20 SAMU-SMUR corresponding to 19 departments in France.

To research the effect of vitamin A to newborn respiratory distress syndrome by intratracheal administration with surfactant.

In a recent multicenter randomized controlled trial, prolonged administration of low-dose methylprednisolone (1mg/kg/day) initiated in early acute respiratory distress syndrome was associated with earlier resolution of pulmonary and extrapulmonary organ dysfunction and reduction in duration of mechanical ventilation and intensive care unit stay. However, glucocorticoids may induce serious adverse events and these adverse events might compensate the positive effect of prolonged methylprednisolone infusion and discourage physicians from treating acute respiratory distress syndrome patients with glucocorticoids. Early prediction of responsiveness to prolonged methylprednisolone infusion would be help to decide whether to continue or not prolonged methylprednisolone infusion and this could reduce the drug related adverse events. We project to evaluate the predictors of responsiveness to prolonged methylprednisolone infusion in early acute respiratory distress syndrome .

Scientific background. Dysregulated systemic inflammation is a key pathogenetic mechanism for morbidity and mortality in ALI/ARDS, and is associated with tissue insensitivity and/or resistance to inappropriately elevated endogenous glucocorticoids. In one study, prolonged methylprednisolone treatment of ARDS patients resulted in rapid and sustained reduction in circulating and pulmonary levels of pro-inflammatory cytokines, chemokines, and procollagen. Preliminary work. Five randomized trials (N = 518) investigating prolonged glucocorticoid treatment in acute lung injury/ARDS reported a significant physiological improvement and a sizable reduction in duration of mechanical ventilation and ICU length of stay. Insufficient data is available on the effects of low dose prolonged methylprednisolone treatment initiated in early ALI/ARDS on mortality. Hypothesis. We hypothesized that the anti-inflammatory activity associated with prolonged methylprednisolone administration improves pulmonary and extra-pulmonary organ dysfunction in early ALI/ARDS and reduces mortality. Objective. To investigate the effects of prolonged low-dose methylprednisolone infusion on mortality and morbidity in early ALI/ARDS. Study design. Multicenter, prospective randomized, placebo-controlled, double-blind clinical trial. Entry criteria. Patients with ALI/ARDS of less than 72 hours duration. Stratification. Patients are prospectively stratified prior to randomization as (1) intubated versus NPPV treated, and (2) ARDS versus severe ARDS. The purpose of stratification is to distribute equally in both arms intubated versus NPPV treated, and ARDS versus severe ARDS. End-points. The primary end-point of trial is 28 days all cause mortality; the secondary end-points are (a) ventilator-free days at 28 days following study entry, (b) organ failure-free days at 28 days following study entry, and (c) duration of ICU stay.

Vibroacoustic pulmonary therapy in patients with COVID19 is believed to have a positive effect on oxygen status and a decrease in the duration of respiratory failure
