Active clinical trials for "Respiratory Distress Syndrome, Newborn"

Determination of the best positive end-expiratory pressure (PEEP) based on oxygenation or driving pressure in patients with acute respiratory distress syndrome (ARDS) after cardiothoracic surgery The use of a positive end-expiratory pressure in acute respiratory distress syndrome is obvious in ARDS management. On the one hand it serves to fight against the reduction of functional residual capacity (FRC) and enable the limitation of hypoxia; and on the other hand it allows the limitation of "opening/closing" lesions in pulmonary alveoli which lead to increase "bio trauma". However elevated PEEP has harmful effect such as hemodynamic effect on the right ventricle and distension on healthy part of the lung.Other adverse effects are: decreasing cardiac output, increased risk of barotrauma, and the interference with assessment of hemodynamic pressures. Ideally the adjustment of PEEP level must be done by taking into account each patient characteristic. PEEP titration based on blood gas analysis is one of the most used techniques by physicians. Current guidelines for lung-protective ventilation in patients with acute respiratory distress syndrome (ARDS) suggest the use of low tidal volumes (Vt), set according to ideal body weight (IBW) of the patient, and higher levels of positive end-expiratory pressure (PEEP) to limit ventilator-induced lung injury (VILI). However, recent studies have shown that ARDS patients who are ventilated according to these guidelines may still be exposed to forces that can induce or aggravate lung injury. Driving pressure (DP) is the difference between the airway pressure at the end of inspiration (plateau pressure, Ppl) and PEEP. Driving pressure may be a valuable tool to set PEEP. Independent of the strategy used to titrate PEEP, changes in PEEP levels should consider the impact on driving pressure, besides other variables such as gas exchange and hemodynamics. A decrease in driving pressure after increasing PEEP will necessarily reflect recruitment and a decrease in cyclic strain. On the contrary, an increase in driving pressure will suggest a non-recruitable lung, in which overdistension prevails over recruitment. The main purposes of this study are to assess the optimal PEEP based on the best driving pressure or the best oxygenation.

This is a phase I/II trial in preterm infants aimed at identifying the optimal dose of budesonide with bovine lipid extract surfactant as vehicle for intratracheal administration.

Acute lung injury (ALI) and the more severe manifestation, acute respiratory distress syndrome (ARDS) describe syndromes of acute onset, bilateral, inflammatory pulmonary infiltrates and impaired oxygenation. ARDS/ALI are a continuum of disease which results in a life threatening, rapidly progressive illness and occurs in critically ill patients. Recent reports in the Journal of the American Medical Association (JAMA) highlight the significant public health impact ARDS/ALI has on the critically ill population in that despite robust research efforts, these illnesses continue to be under diagnosed, under treated, and continue to have a high mortality rate (≥ 40% of all confirmed diagnoses). The estimates for ARDS/ALI incidence vary due to inconsistencies with proper diagnosis and lack of valid biomarkers of disease; however, it is expected that anywhere from 20-50% of patients on mechanical ventilation will develop this disease. Previous work by our group has shown that sphingolipids play a multifaceted role in lung inflammation. Sphingolipid are a class of bioactive lipids that play a role in cellular processes such as apoptosis, cell migration, and adhesion. Ceramide is one species of sphingolipid the investigators have examined in both man and mouse. Our laboratory has shown that ceramide is up-regulated in pulmonary inflammation in mouse models of pneumonitis and is elevated in the exhaled breath condensate of mechanically ventilated patients at risk for ARDS/ALI. Our work coupled with the work of others highlighting a role for ceramide in chronic obstructive pulmonary disease (COPD), surfactant dysfunction, and infectious disease make ceramide a logical candidate biomarker that warrants further investigation. To our knowledge, there are no studies examining the role of ceramide as a biomarker in ARDS/ALI. Thus, our overarching hypothesis is that ceramide is elevated in the lungs of patients who develop ARDS/ALI. This lipid dysregulation accounts for the pathophysiology seen in this disease and may be a potential pharmacologic target for clinical treatment. Thus the purpose of this exploratory research is to maximize existing specimens to further evaluate ceramide as a biomarker for acute lung injury.

INTRODUCTION: Electrical impedance tomography is a tool for noninvasive monitoring of pulmonary ventilation in real time, which is used during alveolar recruitment maneuvers in patients with acute respiratory distress syndrome. OBJECTIVES: To identify ventilatory and hemodynamic changes during the alveolar recruitment maneuver in children with acute respiratory distress syndrome using electrical impedance tomography. METHODS: Twenty children, aged 4 to 12 years, who present a diagnosis of respiratory distress syndrome, with indication of alveolar recruitment admitted to the Pediatric Intensive Care Unit of the Santa Casa de Misericórdia Foundation of Pará will be selected. Data collection will consist of three before the alveolar recruitment maneuver, immediately after the alveolar recruitment maneuver, 2 hours after the alveolar recruitment maneuver, where the pulmonary ventilation distribution, the driving pressure, the real-time reading compliance will be analyzed. tomography of the Timpel brand, autonomic heart rate modulation through the Polar® RS800CX device, physiological variables such as heart rate, oxygen pulse saturation and blood pressure by measuring the DIXTAL multi-parameter monitor, blood oxygen pressure and the oxygen content dog. The statistical analysis will be performed in the Biostat 5.2 program, and the choice of tests will depend on the types of distributions found and the homogeneity of the respective variances.

This study evaluates the addition of budesonide to poractant alfa to prevent bronchopulmonary dysplasia in preterm infants with respiratory distress syndrome. Half of the participants will receive budesonide and poractant alfa in combination, and the other half will receive poractant alfa with saline.

Non-invasive ventilation can allow to avoid intubation and improve outcomes in moderate-to-severe COVID-19-associated acute respiratory distress-syndrome (ARDS). Data on NIV parameters adjustment based on expanded respiratory and gas exchange monitoring in COVID-19 associated ARDS is limited. Appropriate adjustment of the inspiratory positive airway pressure (IPAP) set as a point of the balance between minimal work of breathing (minimum point of W.Patrick scale for assessment of the accessory respiratory muscles and minimum diaphragm thickening fraction) and minimum tidal volume, and respiratory rate can decrease NIV failure in moderate-to-severe COVID-ARDS. The objective of the study is to evaluate the ability of non-invasive ventilation guided with expanded respiratory monitoring to decrease the intubation rate in in moderate-to-severe COVID-ARDS.

Prone position (PP) is standard of care for mechanically ventilated patients with severe acute respiratory distress syndrome in the intensive care unit (ICU). Recommendations suggest PP durations of at least 16 hours. In 2020, COVID-19 pandemic led to a great number of patients requiring mechanical ventilation and PP in the ICU. Risk of ICU staff viral contamination and work overload led to prolongation of PP duration up to 48 hours. Here investigators report outcomes of prolonged PP sessions in terms of skin complications (pression injuries) and ventilatory improvement.

compare and evaluate the effect of use of ultrasonic criteria of weaning versus the conventional ways of weaning in post-traumatic acute respiratory distress syndrome (ARDS) patients who were ventilated for a long time. And compare their effect on the duration of ICU stay.

Secondary infections remain a major cause of mortality in critically ill patients, mainly because of high prevalence of multidrug-resistant microorganisms. Therefore strategies aimed to reduce the incidence of ventilator-associated pneumoniae (VAP) and bloodstream infections are of utmost important. There is robust data on selective digestive decontamination (SDD) efficacy in reduction of secondary infections in intensive care units (ICU) with low rates of antibacterial resistance. However the data received from hospitals with moderate-to-high rates of resistance is equivocal. This as an interventional parallel open-label study investigating the effect of selective digestive decontamination on the rates of ventilator-associated pneumonia in critically ill patients admitted to the ICU with high prevalence of drug-resistant bacteria. Secondary outcomes include rates of bloodstream infections, mortality, duration of mechanical ventilation, duration of ICU stay, resistance selection and overall antibiotic consumption.

57 patients with Adult Respiratory Distress Syndrome (ARDS) requiring Extracorporeal membrane oxygenation (ECMO) therapy were analyzed retrospectively. 28 patients had received immunglobulin M-enriched immunoglobulin therapy (IVIG); 29 patients did not receive IVIG therapy. These patients were analyzed regarding length of stay in intensive care unit (LOS ICU), length of stay (LOS) in hospital and regarding mortality.
