Titration of PEEP During Mechanical Ventilation in Patients With ARDS Using Electrical Impedance...
Acute Respiratory Distress SyndromeLung units that participate in gas exchange are known as 'recruited' lung. Patients with lung injury suffer from a proportion of units that do not participate in gas exchange (i.e. the derecruited lung), which results in impaired gas exchange and induces an inflammatory cascade. The level of PEEP is often coupled to indices of oxygenation such as PaO2, PaO2 to FIO2 ratio, or oxygen index. Currently, two strategies are widely accepted and considered equivocal, one strategy using a lower PEEP level coupled to a certain oxygen requirement, the other using a higher PEEP level. The primary purpose of this study is to demonstrate the safety and efficacy of an electrical impedance tomography (EIT) PEEP titration protocol designed to recruit collapsed lung in children with ARDS and properly maintain lung volumes by setting an optimal PEEP level. A safety system has been developed using the ARDSnet FIO2/PEEP High (upper threshold limit) and Low (lower threshold limit) algorithm. Efficacy will be defined as an improvement in lung volume as assessed by electrical impedance tomography, lung compliance and by an improvement in markers of gas exchange. Safety will be defined as the incidence of barotrauma and hemodynamic consequences that occur during the protocol. Those results will be compared to incidences of barotrauma and hemodynamic compromise within the ARDS literature. Knowledge gained from this pilot will be instrumental in developing an EIT imagine guided protocol which will allow us to conduct future RCTs utilizing EIT technology

The Possible Effect Of Amniotic Fluid pH On Neonatal Morbidities In Maternal Inflammation/Infection...
Respiratory Distress SyndromeTransient Tachypnea of Newborn1 moreAmniotic fluid (AF) pH can be affected by the maternal and/or fetal conditions such as PPROM, prematurity or fetal distress. It is known that fetal urine is the major content of AF since 20th gestational week. Besides fetal alveolar fluid (FAF), gastrointestinal tract, umbilical cord and fetal side of placenta are important sources for AF. Bombesin-like peptides, 8-hydroxydeoxyguanosine in fetal urine and leukotriene E(4), lecithin, sphingomyelin, lamellar body in FAF are molecules acting on fetal lung maturation. Varying levels of these molecules relevant to the stage of lung maturation may constitute an association to AF pHTo detect the possible effect of AF pH on neonatal respiratory morbidities 1 milliliters of AF is aspirated during C-section before incision of membranes. pH value of AFs were analyzed by the blood gas machine (Siemens RAPIDLab®1200 Systems) of NICU. Maternal and neonatal demographic features and clinical outcomes, incidences of morbidities such as respiratory distress syndrome (RDS), transient tachypnea of the newborn (TTN) are all recorded.
Characterization of the Cord Blood Stem Cell in Situation of Neonatal Asphyxia
Respiratory Distress SyndromeNeonatal anoxic-ischaemic enkephalopathy is a dramatic perinatal complication due to brain asphyxia. Neurological and neurosensory sequelae are frequent in survivors, due to neuronal damage and loss. For the moment, only total or partial body hypothermia can partially prevent cell loss. However, no treatment exists to restore neuronal functions. Cord blood stem cells are a promising treatment for the near future. However, before conducting a clinical trial to evaluate the safety and feasibility of autologous cell therapy in neonatal asphyxia, in vitro characterization of the cord blood stem cell in situation of neonatal asphyxia, compared to normal situation, is needed. The primary objective of this study is to characterize cord blood stem cells of neonates with neonatal asphyxia and to compare them with those from healthy newborn. The quantitative and qualitative, functional characterization will insist on cell populations which could potentially participate to neuronal regeneration. Secondary objectives are to assess such characteristics in conditions of cryo-preservation, compared to fresh cell preparation
Effects of Volume Guarantee With Pressure Supported vs. Synchronized Intermittent Mandatory Ventilation...
Respiratory Distress SyndromeStudies in preterm infants have shown that adding volume guarantee (VG) to synchronized modes of ventilation is not only feasible but also advantageous for providing more constant and desirable mechanical breath size. This ideally minimizes ventilator-induced lung injury due to barotrauma and volutrauma. To date, only one recent study has investigated the relative advantages of combining VG with different modes of synchronized mechanical ventilation in clinically stable, preterm infants that were mechanically ventilated at an average age of one month. We aim to further evaluate the effects of PSV+VG versus SIMV+VG ventilation in very low birth weight infants within the first three to five days of life. Our hypothesis is that in very low birth weight infants requiring mechanical ventilation in the first three to five days of life, PSV+VG will allow for more stable physiologic and ventilatory parameters compared to SIMV+VG. The primary endpoints are a reduction in respiratory rate and average mean airway pressure in the PSV+VG group compared to the SIMV+VG group.
