The Effect of Lt to Rt Shunt Using Veno-veno-arterial Extracorporeal Membrane Oxygenation (ECMO)...
Interstitial Pulmonary Fibrosis ARDSCOPD (Chronic Obstructive Pulmonary Disease)4 moreECMO(Extracorporeal membrane oxygenation) is being essential for cardiopulmonary failure patients. There are two types of ECMO, which is veno-veno (V-V) that can be used in respiratory failure patients and veno-arterial (V-A) that can be used in cardiac failure patients. V-A ECMO can also be used during lung transplantation, substitution of cardiopulmonary bypass, which can show sufficient performance during operation and better postoperative outcome. However, regarding V-A ECMO circulating from femoral vein to femoral artery, there is a pro blem of differential hypoxia which might influence coronary artery and head vessels. In this prospective study, the investigators are planning to put another ECMO catheter into internal jugular vein which takes a role of left to right shunt, to mitigate the hypoxia of coronary artery.
Fluid Restriction in Respiratory Distress of the Newborn
Respiratory Distress SyndromeNewbornThe object of this study is to determine the best way to care for infants with respiratory distress. The investigators are testing a method of feeding fluids to infants with respiratory distress in amounts similar to what healthy breastfed babies eat when they are feeding on demand, and comparing this method to the current standard of care for feeding fluids to infants with respiratory distress. These methods of feeding fluids to the study infants will continue until the infants are able to feed normally by mouth. The study will include about 400 infants across five sites in the United States, Chile and Argentina.
Trans-pulmonary Pressure in ARDS
Acute Respiratory Distress SyndromeAdequate PEEP selection in ARDS is still a matter of research. The main objectives of using PEEP in ARDS are improvement in oxygenation, lung recruitment at the end of expiration, prevention of opening and closing of terminal respiratory units at minimal hemodynamic compromise. The challenge is to carry out these objectives in a patient-centered approach based on individual characteristic of lung pathophysiology. Recently, it has been proposed to set PEEP from the trans-pulmonary end-expiratory pressure. Trans-pulmonary pressure (Ptp) is obtained from the difference between airway pressure and measured esophageal pressure (Pes). Measured Pes values have been found positive in the supine position in ARDS patients, leading to negative values of Ptp. The strategy proposed by Talmor and coworkers is to adjust PEEP up to get Ptp between 0 and 10 cm H2O. Whether this strategy improves survival is under investigation. Prone position ventilation significantly improves survival in severe ARDS as demonstrated by meta-analyses and a recent multicenter randomized controlled trial. The purpose of present project is to investigate Ptp at end-expiration in the prone position in severe ARDS. The project is centered on the question about what are the values of measured Pes in prone position. The hypothesis is that they are lower than in the supine position due to the relief of the weight of heart, mediastinum and lung and also to recruitment of dorsal lung regions. To investigate this hypothesis, measured Pes, Ptp, end-expiratory lung volume, overall lung recruitment (pressure-volume curve), and regional recruitment by using electrical impedance tomography. will be assessed in supine then in the prone position across two different strategies of PEEP selection, PEEP/FIO2 table and Talmor proposal.
Weaning Preterm Neonates From Nasal Continuous Positive Airway Pressure
Respiratory Distress SyndromeHyaline Membrane Disease2 moreThere is little data published concerning the best approach to nasal continuous positive airway pressure (nCPAP) weaning. Potential complications associated with prolonged nCPAP therapy include gastric distension, nasal trauma,pneumothorax,agitation and nosocomial infection. Moreover, Infants on nCPAP may also require more intensive nursing care and the use of extra equipment. Therefore, minimizing the amount of time that a patient requires CPAP may be beneficial. On the other hand, removing CPAP too early may lead to complications that include: increasing apnea, increased oxygen requirement, increased work of breathing, the need to re-start CPAP, and intubation and mechanical ventilation. Moreover, an experimental study have demonstrated an improvement in lung growth after the prolonged use of CPAP. Nasal cannula (NC) flows at 1-2 L/min may also generate a positive pressure in the airway of preterm infants. The use of NC flow to generate positive airway pressure would minimize many of the application issues of nCPAP. However, NC systems used in neonates routinely employ gas that is inadequately warmed and humidified, limiting the use of such flows due to increased risk of nasal mucosa injury, and possibly increasing the risk for nosocomial infection. The purpose of this randomized controlled trial is to evaluate the clinical impact of two methods for weaning preterm infants from nCPAP.
Intrapulmonary Percussive Ventilation (IPV) Versus Nasal Continuous Positive Airway Pressure Ventilation...
Respiratory Distress SyndromeNewbornDuring caesarean section, transient respiratory distress which occurs frequently (3%) with possible complications are at present managed by non invasive nasal continuous positive airway pressure ventilation (nCPAP) associated with oxygen therapy. Intrapulmonary Percussive Ventilation (IPV) is a non-invasive ventilatory mode used in some intensive care units to treat some respiratory distress syndrome of the newborn with a good tolerance, but without evaluation in prospective studies

Respiratory Distress SyndromePreterm Birth1 moreThis is an unblinded, randomized, controlled, crossover (AB/BA) trial of surfactant treatment with LISA vs. INSURE in a manikin simulating an extremely low birth weight infant. Participants will be level III NICU consultants and residents. Randomization will be performed using a computer-generated random assignment list. The primary outcome measure will be the total time of device positioning. The secondary outcomes will be the success of the first and the participant's satisfaction.
