Active clinical trials for "Respiratory Distress Syndrome"

Cytokine hemoadsorption is a novel therapy used to improve outcome in critically ill patients with a dysregulated cytokine response and hemodynamic instability. Patients on extracorporeal membraneous oxygenation (ECMO) often develop severe systemic inflammatory response syndrome (SIRS). Cytokine removal using different types of hemoadsorption devices is believed to block the vicious circle of inflammation dysregulation when other basic therapeutic measures fail. To date there are very limited reports on ECMO and cytokine hemoadsorption combination therapy. The aim of this retrospective study is to evaluate feasibility and effectiveness of hemoadsorption in veno-arterial and veno-venous ECMO patients.

Prospective, mono centric study on COVID-19 patients with or without acute respiratory distress syndrome (ARDS) to analyse the dynamics of the immune response and to search for biomarkers of evolution

This study intended to evaluate the effects of commonly used diuretic, spironolactone, on oxygenation in covid-19 ARDS patients.

The primary aim of this study is to evaluate the effect of physical rehabilitation performed in intensive care unit on the range of joint motions and muscle strength of survivors following discharge from intensive care unit in patients with COVID-19. Secondary outcome is to assess the duration of mechanical ventilation, length of stay in intensive care unit and in hospital, and mortality rates during intensive care unit stay and health related quality of life following discharge in survivors. Until April 14 patients were provided all the intensive care managements except for rehabilitation and patients discharged before this time constituted the 'non-rehabilitation' group (n=17). Patients discharged after April 14 were provided rehabilitation in addition to usual intensive care unit care and constituted the study 'rehabilitation' group (n=18). Passive range of motion exercises to each joint and neuromuscular electrical stimulation to bilateral quadriceps and tibialis anterior muscles were applied 6 days/week in the 'rehabilitation' group during intensive care unit stay.

Several studies suggested that ARDS may have important adverse effects on renal function, but few studies have specifically addressed the risk factors of AKI and its impact on the outcome in theses patients.

For therapy of respiratory distress syndrome (RDS) in premature babies, there are several established options. An important therapeutic aspect is the tracheal administration of exogenous surfactant into the child's lung. In the recent years, several methods have been developed. The methods differ in the selected ventilation mode (intubation with mechanical ventilation vs. Continous Positive Airway Pressure (CPAP)-supported spontaneous breathing) and in the way in which the application of surfactant is technically conducted (via endotracheal tube, endotracheal catheter or nebulization). In selection of ventilation technique, there is an upcoming trend towards less invasive respiratory support via CPAP. While this may increase the rate of complications on the one side (i.e. pneumothorax), it shows much lower oxygen demand and a shorter need for mechanical ventilation on the other side. In the selection of the administration technique, different methods were repeatedly developed to adapt the surfactant administration to the CPAP therapy. In this study, a newly developed and in the European Community now certified (CE-Mark) application aid (Neofact) will be tested for the first time on preterm infants, to verify the feasibility.

With the birth of Mechanical Ventilation in the 1950s came the ventilation induced lung injuries (VILI). Numerous works have since then shown the benefit of "protective ventilation", notably by controlling the delivered tidal volume and pressures. However, as the respiratory condition improves and the weaning is started by shifting to Pressure Support Ventilation (PSV), these parameters stop being tightly controlled. This study aims to determine whether there is a relationship between the driving pressure measured in PSV and the weaning time.

In 1967, Ashbaugh et al first described 12 patients with a syndrome characterized by the acute onset dyspnea, severe hypoxemia, diffuse lung infiltrates on the chest radiography and decreased lung compliance. Moreover, in 1988, Murray et al proposed a lung injury scoring system based on the level of positive end-expiratory pressure (PEEP), PaO2-to-FiO2 ratio, static lung compliance, degree of infiltrates on the chest radiograph, and clinical cause. A score of 2.5 or greater was considered to be consistent with a diagnosis of ARDS. The current definition of ARDS was proposed by Bernard et al and the American-European Consensus Conference in 1994. The criteria of ARDS included: 1) acute onset; 2) a PaO2/FIO2 ratio, or hypoxia score, of < 200, regardless of positive endexpiratory pressure; 3) bilateral infiltrates on chest radiograph; and 4) a pulmonary artery occlusion pressure of <18 mm Hg or the absence of clinical evidence of left atrial hypertension. However, despite advances in ventilator management, the mortality rate of acute lung injury and the acute respiratory distress syndrome remains very high (approximately 40 to 50 percent). In 2000, ARDS Network trial compared the effects of 6 versus 12 mL/kg of tidal volume per predicted body weight (PBW) among 861 patients and noted an overall 22% reduction in mortality rate, more ventilator-free days, and more organ-failure-free days in the low-tidal-volume group. Therefore, the current approach to mechanical ventilation of a patient with ARDS emphasizes the use of lower tidal volumes with lower pressures to avoid causing lung overdistension and ventilator associated lung injury. Nevertheless, one year after publication of the ARDSnet trial, Rubenfeld et al noted that lung-protective ventilation strategies were applied in less than 5% of patients with ARDS or ALI at a single ARDSnet center. Rubenfeld et al found that common barriers to the initiation of low tidal volume ventilation include unwillingness to relinquish control of the ventilator, failure to recognize patients as having ALI/ARDS, and perceived contraindications to low tidal volume ventilation. Significant barriers to the continuation of low tidal volume ventilation include concerns regarding patient discomfort and tachypnea or hypercapnia and acidosis. In addition, Kalhan et al also evaluated factors associated with the choice of tidal volume and he reported that underuse of LPV may be related to clinicians' under-recognition of less severe cases of ALI, and their reserving of low-tidal volume ventilation for more severe cases, or both. However, the factors such as comorbidity and pathophysiological change associated with underuse of lung protective ventilation strategy are not clear. The investigators perform a prospective single-center study to investigate the factors associated with the use of lung protective ventilation strategy (LPV) in ALI/ARDS patients in ICU.

Non-invasive positive pressure ventilation (NIV) refers to the provision of mechanical ventilation without an artificial airway (for example, an endotracheal tube). Over the past decade, evidence from randomized control trials has accumulated to demonstrate effectiveness of the technique in avoiding intubation, reducing complications associated with intubation, shortening ICU and hospital lengths of stay, and reducing mortality rates in selected patients with acute respiratory failure. However, NIV is still underutilized at many medical centers. The purposes of this project will be to acquire information related to NIV use, to identify reasons for underutilization, to implement interventions that encourage more appropriate use of NIV, and to evaluate the effectiveness of the interventions. Reliable information on NIV use as well as analysis of reasons for underutilization will provide insight into ways of enhancing NIV use. We will determine utilization rate, technology used, patient diagnoses, duration of ventilator use and hospital stay, and success rates as recorded on case report forms (CRFs). After completing the survey, we will provide an educational program to randomly selected institutions (one-half of the total) aimed at increasing the knowledge and skill of physicians, nurses, and therapists regarding use and implementation of NIV. Data will be gathered for a second round with the same data-gathering instruments used during

To investigate risk factors in bronchopulmonary dysplasia (BPD) and to elucidate the relationship between BPD, acute lung disease severity, respiration-related variables, water balance, nutrition, familial predisposition, and environmental, pregnancy, and delivery parameters.
