NIPPV and nBiPAP Methods in Preterm Infants With Respiratory Distress Syndrome
PrematurityRespiratory Distress SyndromePurpose is to compare introduction of NIPPV (Nasal Intermittent Positive-Pressure Ventilation) and nBiPAP (Nasal Bi-level Positive Airway Pressure) in terms of mechanical ventilation (MV) need (non-invasive respiratory support failure) and surfactant need within the first 72 hours of life in preterm infants with Respiratory Distress Syndrome (RDS) at 26-30 weeks of gestation.
Diaphragm Electrical Activity of Preterm Infants on nCPAP With Binasal Prongs Versus RAM Cannula...
Preterm InfantsRespiratory Distress Syndrome3 morePreterm babies have immature lungs and frequent pauses in their breathing which often necessitates breathing support. Nasal Continuous Positive Airway Pressure (nCPAP) is one of the most commonly used tools, but the standard interfaces (prongs or mask) may cause nasal-septal injury and discomfort. The RAM cannula is another interface that consists in soft and curved prongs to avoid this nasal injury, but as the seal is not 100%, suboptimal delivery of airway distending pressure could result if they are used to deliver CPAP, as compared to standard interfaces. The investigators plan to study very low birth weight preterm babies who are generally well but require some support with their breathing. By inserting a special feeding tube with sensors into the stomach, the investigators can measure the electrical activity of the diaphragm (EAdi), which is an important muscle for breathing. By analyzing EAdi in babies receiving nCPAP either with prongs or ram cannula, the investigators will be able to measure and compare how each method of support affects a baby's breathing. This important study will help us determine the most appropriate breathing support for preterm babies.
Amniotic Fluid Optical Density Determination as a Test for Assessment of Fetal Lung Maturity.

Esophageal Pressure-Guided Optimal PEEP/mPaw in CMV and HFOV: The EPOCH Study
Respiratory Distress SyndromeAdult1 moreThe use of positive end-expiratory pressure (PEEP) has been shown to prevent the cycling end-expiratory collapse during mechanical ventilation and to maintain alveolar recruitment, keeping lung portions open, increasing the resting end-expiratory volume. On the other hand PEEP may also overdistend the already open lung, increasing stress and strain. Theoretically high frequency oscillatory ventilation (HFOV) could be considered an ideal strategy in patients with ARDS for the small tidal volumes, but the expected benefits have not been shown yet. PEEP and HFOV should be tailored on individual physiology. Assuming that the esophageal pressure is a good estimation of pleural pressure, transpulmonary pressure can be estimated by the difference between airway pressure and esophageal pressure (PL= Paw - Pes). A PL of 0 cmH2O at end-expiration should keep the airways open (even if distal zones are not certainly recruited) and a PL of 15 cmH2O should produce an overall increase of lung recruitment. The investigators want to determine whether the prevention of atelectrauma by setting PEEP and mPaw to obtain 0 cmH2O of transpulmonary pressure at end expiratory volume is less injurious than lung recruitment limiting tidal overdistension by setting PEEP and mPaw at a threshold of 15 cmH2O of transpulmonary pressure. The comparison between conventional ventilation with tidal volume of 6 ml/Kg and HFOV enables us to understand the role of different tidal volumes on preventing atelectrauma and inducing lung recruitment. The use of non-invasive bedside techniques such as lung ultrasound, electrical impedance tomography, and transthoracic echocardiography are becoming necessary in ICU and may allow us to distinguish between lung recruitment and tidal overdistension at different PEEP/mPaw settings, in order to limit pulmonary and hemodynamic complications during CMV and HFOV.
Identifying PARDS Endotypes
Respiratory Distress SyndromeRespiratory Distress Syndrome1 morePediatric acute respiratory distress syndrome (PARDS) is a severe and diffuse lung injury that is a common cause of admission and mortality in the pediatric intensive care unit (PICU). PARDS can be secondary to many different causes, and there are few therapies that have been shown beneficial in PARDS. This study seeks to identify important PARDS subtypes using gene expression profiling of bronchial epithelial cells from control and PARDS subjects.
Efficacy of Combining Prophylactic Curosurf With Early Nasal CPAP in Delivery Room: the Curpap Study...
Respiratory Distress SyndromeNewbornThe primary objective of this study is to compare two methods of post-delivery stabilization and subsequent early respiratory care for reducing the need for MV and related secondary complications, such as BPD, in premature babies at high risk of RDS: Early stabilization on nCPAP Intubation, prophylactic surfactant (Curosurf®) administration shortly after delivery, and rapid extubation to nCPAP. The data obtained from this comparison will be applied to test the hypothesis that preterm neonates at risk of RDS who are treated with prophylactic surfactant + nCPAP show less need for MV when compared to infants who receive nCPAP alone.

Acute Lung InjuryAcute Respiratory Distress Syndrome1 moreThe purpose of this study in patients suffering from acute lung injury is to determine whether positive end-expiratory pressure (PEEP) setting guided by electrical impedance tomography (EIT) influences pulmonary gas exchange, lung mechanics, ventilation/perfusion matching and homogeneity of regional ventilation when compared to other PEEP setting strategies such as the open lung concept or the ARDSnet protocol.

Validation of a Semi-automatized Method to Detect Cyclic Hyperinflation on CT-scan in ARDS
Acute Respiratory Distress Syndrome (ARDS)This study aims to validate a semi-automatized method to quantify cyclic hyperinflation on CT-scan of ARDS patients. The gold standard will be cyclic hyperinflation assessed on the same CT scan, using manual segmentation of the lung.
