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.

Acute Respiratory Distress SyndromeCompared with placebo, evaluate the effects and safety of Ulinastatin(UTI) added to conventional treatment for ARDS; Evaluate the dose response relationship of Ulinastatin for 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.
Non Invasive Ventilation in Abdominal Postoperative Period
SurgeryTrauma to the Abdomen1 moreAcute respiratory failure may occur early in the postoperative course, requiring endotracheal intubation and mechanical ventilation in selected patients, thus increasing morbidity and mortality and prolonging intensive care unit (ICU) and hospital stay.We will perform a multicenter, prospective, randomized clinical trial to compare the efficacy of non invasive ventilation (NIV) which associated pressure support ventilation (PSV: 5 to 15 cmH2O) and positive end expiratory pressure (PEEP: 5 to 10 cmH2O) with standard oxygen therapy in the treatment of postoperative acute respiratory failure. We also set out to examine the hypothesis that early application of NIV may prevent intubation and mechanical ventilation in patients who develop acute respiratory failure after abdominal surgery.
Mesenchymal Stem Cell in Patients With Acute Severe Respiratory Failure
Respiratory Distress SyndromeAdultAlthough the advent of advanced medical support for respiratory failure, the mortality rate of acute severe respiratory failure is still high and the life quality is frequently compromised from pulmonary fibrosis. The investigators hypothesize that the treatment using mesenchymal stem cell can be beneficial in patients with respiratory failure. The present study is a pilot study evaluating the efficacy and safety of mesenchymal stem cell treatment in patients with respiratory failure.
Using Human Menstrual Blood Cells to Treat Acute Lung Injury Caused by H7N9 Bird Flu Virus Infection...
Acute Lung InjuryAcute Respiratory Distress Syndrome (ARDS)1 moreThe purpose of this study is to determine whether human menstrual blood-derived stem cells are effective in the treatment of infection of H7N9 virus caused acute lung injury.
Intranasal Midazolam Versus Intranasal Ketamine to Sedate Newborns for Intubation in Delivery Room...
Respiratory Distress SyndromePrematurity of FetusAnesthesia is rarely used to intubate newborns in delivery room because of the very difficulty of accessing veins. The investigators hypothesized that intranasal administration of sedative would be an effective alternative. -Midazolam and Ketamine are two drugs used during neonates' intubation. They are also used intranasally in the absence of venous access-In a pilot study the investigators have demonstrated that sedation with Midazolam was effective in 67% of the patients. Efficiency was defined by a specific pain score: FANS < 4 (Faceless Acute Neonatal Pain Scale) and by an impedancemetric Pain monitor < 0.2 spike/s. The investigators hypothesized that intranasal ketamine would increase procedure effectiveness from 67 to 90%. Main objective: To compare newborns sedation quality as they are sedated either by intranasal Midazolam or by intranasal Ketamine during intubation in delivery room. Secondary Objectives: To compare intubation quality, hemodynamic and respiratory tolerance, and neurological outcomeat 2 years within the two groups.
The Effect of High Frequency Oscillation on Biological Markers of Lung Injury
Acute Respiratory Distress SyndromeMechanical ventilation, although life-saving, damages the lungs through what is known as ventilator-induced lung injury. High frequency oscillation ventilation has been proposed as a ventilation method that may be less injurious to the lungs than conventional mechanical ventilation and may lead to better patient outcomes. To evaluate this hypothesis, the OSCILLATE trial is comparing outcomes in patients with the acute respiratory distress syndrome randomized to high frequency oscillation ventilation vs conventional lung protective ventilation. The present study is a substudy of the OSCILLATE trial looking at biomarkers of ventilator-induced lung injury in blood samples drawn from patients enrolled in OSCILLATE. The objective is to look for biochemical evidence of decreased ventilator-induced lung injury in patients treated with high frequency oscillation ventilation relative to conventional ventilation.
