Active clinical trials for "Respiratory Distress Syndrome"

Single-center, randomised controlled, cross-over clinical trial in preterm infants born at gestational age below 34+1/7 weeks receiving supplemental oxygen and respiratory support (continous positive airway pressure (CPAP) or non-invasive ventilation (NIV) or invasive ventilation (IV)). Routine manual control (RMC) of the fraction of inspired oxygen (FiO2) will be tested against RMC supported by automatic control (SPOC) with "old"-algorithm and RMC supported by CLAC with "new"-algorithm. The first primary hypothesis is, that the use of the "new" algorithm results in more time within arterial oxygen saturation (SpO2) target range compared to RMC only. The a-priori subordinate hypothesis is, that the new algorithm results in more time within SpO2 target range compared to SPOCold. The second primary hypothesis is, that the use of 2 seconds averaging time of the SpO2 Signal results in more time within arterial oxygen saturation (SpO2) target range compared to the use of 8 seconds averaging interval of the SpO2 signal.

Acute respiratory distress syndrome (ARDS) is a serious disease with high mortality. In patients who survive ARDS, respiratory, neurological and motor sequelae are frequent, negatively impacting on the patient's quality of life, and engendering substantial healthcare costs (rehabilitation, long-term care, delayed return to work). There may also be repercussions on the patient's family and entourage. The severity of ARDS and the burden it represents have underpinned intensive research to identify treatment strategies that could improve mortality. However, it is important to ensure that any improvement in mortality does not come at the price of an excess of sequelae and disability in survivors. The oxygenation strategy used to treat ARDS may have an impact on mortality in these patients. The CLOSE study, in which our group participated, recently demonstrated the feasibility of two oxygenation strategies in intensive care unit (ICU) patients with ARDS. We have also initiated the LOCO-2 study (NCT02713451), whose aim is to show a reduction in mortality in ARDS using a "conservative" oxygenation strategy (PaO2 maintained between 55 and 70 mmHg) as compared to a classical "liberal" oxygenation strategy (PaO2 between 90 and 105 mmHg). The LTO-BLOXY study is a substudy of the on-going LOCO-2 study

The aim of the present study was to investigate the efficacy of L-carnitine therapy on the occurrence and prognosis of respiratory distress syndrome

Severe Covid-19 (Coronavirus Disease 2019) infections generate major but inappropriate production of cytokines and, in some cases, generate anti-IFN (Interferon) auto-antibodies, inducing acute respiratory distress syndrom (ARDS). Therapeutic plasma exchange (TPE) have been reported to be efficient for improving the hyperinflammatory condition state and the respiratory function, which has been described in case reports or small series. The study aims to remove cytokines during cytokine storm and anti-IFN auto-antibodies (when present) to prevent developpement of an inappropriate immune response and to improve the clinical response to reanimation treatment, in particular the respiratory parameters leading to a rapid improvement of clinical status. To that aim, the study investigates to compare a treatment using TPE plus usual treatments in intensive care unit (experimental arm) versus usual treatments in intensive care unit (routine arm) in a randomised trial.

Objective: To compare two de-escalation strategies guided by either extravascular lung water or global end-diastolic volume-oriented algorithms in patients with sepsis and ARDS. Design: A prospective randomized study. Setting: City Hospital #1 of Arkhangelsk, Russia, mixed ICU. Patients: Sixty patients with sepsis and ARDS were randomized to receive de-escalation fluid therapy, guided either by extravascular lung water index (EVLWI, n = 30) or global end-diastolic volume index (GEDVI, n = 30). Intervention: In case of GEDVI > 650 mL/m2 or EVLWI > 10 mL/kg, diuretics and/or controlled ultrafiltration were administered. The primary goal of de-escalation was to achieve the cumulative 48-hr fluid balance in the range of 0 to - 3000 mL. If GEDVI < 650 mL/m2 or EVLWI < 10 mL/kg, the target fluid balance was set from 0 to +3000 mL.

Covid-19 disease is one of the most important health system challenges which is the result of the recent SARS CoV-2 virus outbreak. So far, despite the use of different types of pharmaceuticals, none has been served as a curative treatment and research is continued to find one or more effective drugs; either palliative or curative ones. One of the most important clinical problems in Covid-19 patients is lung involvement, which may causes significant sequels; leading to a main part of morbidity and/or mortality. Surfactant is one of the drugs that can have valuable effects on the lungs, both by reducing the alveolar surface tension and by exerting immunomodulatory effects. In a previous study by the same team, favorable effects were seen in intubated patients; however, the aim of this study was to evaluate the effect of exogenous nebulized surfactant in the pre-intubation stages of the disease.

The aim of the study is to investigate the role of SB 8.4% as adjuvant therapy in the treatment of COVID- 19 patients proved to be RT-PCR positive (mild, moderate and severe).

Previous studies have shown that a positive fluid balance was an independent factor of worse prognosis in ICU patients with acute respiratory distress syndrome (ARDS), and negative fluid balance has been demonstrated to increase oxygenation index, reduce time under mechanical ventilation and ICU length of stay with no noticeable adverse effects. But there is no evidence that faster speed of negative fluid balance would be more beneficial for ARDS patients. So researchers designed the study to prove the effect of negatively fluid balancing speed for ICU patients with ARDS.

No clear recommendation exists for the level of oxygenation of intensive care patients. In Acute Respiratory Distress Syndrome (ARDS), pulsed oxymetry (SpO2) have to be kept between 88 and 95 percent and oxygen alveolar pressure between 55 and 80 mmHg (PaO2). These recommendations are common but do not lie on high scientific knowledge and level of proof. In the major studies of these fifteen last years that changed ARDS management, PaO2 was kept around 85 and 90 mmHg despite current recommendations of 55 to 80 mmHg of PaO2. Many recent review and cohort studies pointed the risk of excessive oxygenation especially following cardiac arrest, stroke or traumatic brain injury. However, these data come in majority from cohort or database study without strong definition of hyperoxia. Data coming from prospective studies are scarce and tend to show better outcome of patients with lower objectives of oxygenation in ICU. High oxygen (O2) level may be deleterious especially on inflammatory lungs. It could enhance injuries due to mechanical ventilation. O2 could be responsable of " hyperoxia induced lung injury ". The investigators showed in a precedent study that comparing a restrictive oxygenation versus a liberal oxygenation was feasable and do not expose patients to major adverse events. More, mortality at 60 days has tendency to be lower. The investigators therefore ask if a lower objectives of PaO2 in comparison with the level usually seen in last studies on ARDS could improve ARDS patients outcome. The aim of this study is to show that a restrictive oxygenation in comparison with a liberal oxygenation strategy in patients with ARDS would lower mortality at 28 days.

Lung protection should start in the delivery room where, from the first breaths, the preterm infant can be helped to clear the lung fluid and to recruit alveolar spaces and establish the functional residual capacity (FRC). Sustained lung inflation (SLI) applied at birth in the delivery room has been demonstrated to lead to clearance of lung fluid and achievement of a precocious functional residual capacity (FRC) both in animal and human studies. SLI associated to an adequate positive end expiratory pressure (PEEP) may help the efficacy of the respiratory effort in lung of preterm infants at risk for respiratory distress syndrome (RDS) and reduce need of mechanical ventilation (MV). Further studies are required to evaluate the clinical utility of this maneuver. The ability to monitor what happens to the lungs while applying different recruitment maneuvers in preterm infants would allow the definition of a procedure that allows optimal assistance to improve the FRC. One promising approach is provided by the forced oscillation technique (FOT). During forced oscillations, a small amplitude sinusoidal pressure stimulus is applied to the airway opening and the mechanical response of the respiratory system is studied by means of the total respiratory input impedance (Zin). Zin is a complex number that can be expressed as real part, called resistance (Rrs), and imaginary part, called reactance (Xrs). Particularly, it has been recently shown that Xrs measured at 5 Hz is very sensible to changes in the mechanics of lung periphery and provides accurate information about lung volume recruitment and derecruitment. The main purpose of this work is to apply FOT to the assessment of lung function in newborns submitted to SLI at birth. The investigators hypothesized that the application in the delivery room of the SLI in the preterm infant is effective in achieving a greater FRC and therefore a greater value of Xrs compared to a control group not treated with the SLI.
