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.
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.
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.
Perfluorocarbon (PFC) Inhalation Treatment of Acute Lung Injury/Acute Respiratory Distress Syndrome...
Respiratory Distress SyndromeAdult1 morePFCs (perfluorocarbons, PFC), an ideal liquid respiratory media, has special chemical and biological properties, including high solubility of gas, swiftness of carrying and release, low surface tension, high proportion, almost non-absorbing and non-metabolic characteristics in the body. On the basis of the strong animal data suggesting the efficacy of PFC vapor inhalation in models of lung injury, we performed a randomized clinical trial comparing PFC vapor inhalation with conventional mechanical ventilation(CMV)in patients with Acute Lung Injury/Acute Respiratory Distress Syndrome(ALI/ARDS). The investigators will apply the Invasive Mechanical Ventilation (IMV) to the vaporized perfluorocarbon inhalation, objectively evaluate its curative effect on the acute respiratory distress syndrome, and meanwhile assess the safety of PFC.
The Safety and Dose Response Relationship of Ulinastatin for Acute Respiratory Distress Syndrome(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.
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.
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.
