Exogenous Surfactant Through Nebulizer Mask on Clinical Outcomes in Covid-19 Patients
COVID-19Respiratory Distress Syndrome1 moreCovid-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 Effect of Negatively Fluid Balancing Speed for ICU Patients With Acute Respiratory Distress...
Fluid LossPrevious 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.
Liberal Oxygenation Versus Conservative Oxygenation in ARDS
Acute Respiratory Distress SyndromeIntensive CareNo 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.
Sustained Lung Inflation and Pulmonary Mechanics in Preterm Infant
Preterm BirthRespiratory Distress Syndrome1 moreLung 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.
Different Effects of Three Recruitment Maneuvers on the Lung Heterogeneity of Acute Respiratory...
Acute Respiratory Distress SyndromeAcute respiratory distress syndrome (ARDS) is the common disease in clinical, which pathophysiology is a lot of alveolar collapse and heterogeneity. Recruitment maneuver is one of the important therapy for improvement of this phenomenon. The previous research focuses on the hemodynamic and oxygenation effect of recruitment maneuver on the lung of ARDS. Seldom investigators try to find the intuitive change of heterogeneity when recruitment maneuver is implemented. In this study, the investigators compare three recruitment maneuvers on the lung heterogeneity of ARDS.

Non-invasive Fluid Management
Respiratory Distress SyndromeAdultFor patients with a condition called acute respiratory distress syndrome (ARDS), managing their fluid levels to achieve a negative balance helps to improve their outcomes. In the past, patients' fluid levels were monitored with central lines placed into the bloodstream. However, most patients are now managed without central lines. A device called a NICOM (noninvasive cardiac output monitor) which monitors patients' heart function, using a few patches which are attached to their chest, may be useful in managing fluid levels without central lines. This study will compare the fluid balance in patients who are managed with typical care to the fluid balance in patients who are managed with the NICOM device.
Efficacy of Bevacizumab in Preventing Acute Respiratory Distress Syndrome (ARDS)
Severe SepsisAcute Respiratory Distress SyndromeThis study aims to test the effectiveness of a single intravenous (IV, through the vein) dose of the study drug, bevacizumab (Avastin), in preventing/reducing the development of Acute Respiratory Distress Syndrome (ARDS), in patients with severe sepsis, who are at high risk for developing ARDS. ARDS is a lung disease caused by a lung injury that leads to lung function impairment. The condition the patient has,severe sepsis, is a medical condition associated with an infection characterized as an immune system inflammatory response throughout your whole body that can lead to organ dysfunction, low blood pressure or insufficient blood flow to one or more of your organs.
Impact of Fluid Resuscitation Therapy on Pulmonary Edema as Measured by Alveolar Fluid Clearance...
Acute Respiratory Distress Syndrome (ARDS)Hypovolemia1 moreThe need for fluid resuscitation (FR) in ICU patients with acute respiratory distress syndrome (ARDS) is common. Indeed, relative or absolute hypovolemia is a common phenomenon that the intensivist must recognize early and treat promptly. Fluid challenge may have adverse side effects associated with fluid administration. The diffusion within the interstitial space may favor edema formation and cause cardiac dysfunction by volume overload. Edema formation is global and may specifically alter pulmonary alveolar epithelial integrity, leading to enhanced alveolar edema and impaired gas exchange. Currently, two types of fluids are frequently used, crystalloids and colloids. Among colloids and compared to crystalloids, albumin has the theoretical advantage of causing greater volume expansion. We hypothesized that a fluid resuscitation therapy with albumin generates less pulmonary edema than a fluid resuscitation therapy with crystalloids. The aim of our study is to compare alveolar fluid clearance, as a marker of alveolar edema fluid resorption, in 2 groups of patients: those treated with albumin and those treated with crystalloid.
