Active clinical trials for "Respiratory Distress Syndrome, Newborn"

The aim of this study is to investigate two different strategies for the withdrawal of CPAP in preterm infants born before 32 weeks of gestation.

Respiratory distress syndrome (RDS) is the most common respiratory disorder in preterm infants. Despite improved survival of extremely premature infants with RDS, complications related to mechanical ventilation still occur. This trial will attempt to maintain adequate gas exchange at a rapid rate, short inspiratory time, low tidal volume, and low peak inspiratory pressure in infants with respiratory distress requiring mechanical ventilation. A cross over design will be used to test the hypothesis whether mid-frequency ventilation in preterm infants with RDS requiring mechanical ventilation will reduce the peak inspiratory pressure requirement when compared to conventional mechanical ventilation.

The primary objective of this research is to compare the need for intubation and mechanical ventilation in the first seven days of life for infants with respiratory distress syndrome (RDS) on nasal continuous positive airway pressure (nCPAP) who receive surfactant via a Laryngeal Mask Airway (LMA) with those who are maintained on nCPAP and do not receive surfactant.

The present study will test the use of very early nasal continuous airway pressure(NCPAP)with and without surfactant in premature infants with clinical evidence or respiratory distress syndrome. We hypothesize that premature infants exposed to very early NCPAP and surfactant will require less mechanical ventilation compared to those premature infants exposed to NCPAP alone.

Acute respiratory distress syndrome (ARDS) is a common and catastrophic complication of critical illness related to burns, motor vehicle accidents, or overwhelming infection. ARDS kills 40-70% of affected patients. Patients with ARDS require life support in the form of a ventilator to breathe for them while their lungs heal. Ironically, ventilators can cause further damage to the lungs. We are conducting a study comparing 2 methods to protect the lungs from further damage. One method uses standard mechanical ventilators and the other uses a new type of ventilator, called a high frequency oscillator. We propose to test whether this high frequency oscillation will reduce the relative risk of dying from ARDS. 72 patients from 12 intensive care units in Canada and Saudi Arabia will participate in this preliminary study to test the feasibility of our study methods. If feasible, we plan to move on and conduct a large multinational study to definitively answer this question.

The purpose of this study is to determine whether the 2mg/kg administration of corticosteroids, in the form of methylprednisolone sodium succinate, in early phase acute respiratory distress syndrome after thoracic surgery, will reduce the postoperative mortality.

The objective of our study is to carry out an evaluation of the safety and the effectiveness of the use of the MakAir respirator as useful supplement in situation of shortage of technical devices of assistance to the mechanical invasive ventilation, related to COVID-19 through a protocol in 3 successive sequences.

The objective is determine the strain measured at the bedside could be a dynamic prognostic marker of during Acute respiratory Distress Syndrome (ARDS).

Pulmonary recruitment maneuvers open these lung areas and appropriate adjustment of positive expiratory pressure (PEP) helps to stabilize recruitment and reduce the stress associated with alveolar opening and closing. Its beneficial effects in the lung affected by Acute Respiratory Distress Syndrome (ARDS) remain unclear. The hypothesis is that there is a heterogeneous effect of the recruitment maneuver according to the phenotype of ARDS. It is important to be able to define responder patients from non-responders to this recruiting maneuver.

Acute Respiratory Distress Syndrome (ARDS) still remains associated with a mortality rate of 30 - 45 % despite improvement in mechanical ventilation. Driving pressure, defined as the difference between the end-inspiratory and the end-expiratory airway pressure, appears as an important factor contributing to mortality in patients with the ARDS. In patients already receiving a conventional tidal volume of 6 ml/kg predicted body weight (PBW), a driving pressure ≥ 14 cmH2O increases the risk of death in the hospital. One mean to lower the driving pressure is to decrease the tidal volume such that from 6 to 4 ml/kg predicted body weight. However, this strategy promotes hypercarbia by reducing the alveolar ventilation, providing the respiratory rate is constant. In this setting, implementing an extracorporeal CO2 removal (ECCO2R) therapy may offset the associated hypercarbia. The investigators have previously demonstrated that combining a membrane oxygenator within an hemofiltration circuit provides efficacious low flow ECCO2R on a renal replacement therapy monitor. In this study, we thought to investigate the efficacy of the PrismaLung stand-alone therapy. Using a PrismaFlex monitor and a HP-X circuit, a neonatal membrane oxygenator (PrismaLung) is used to provide decarboxylation without renal replacement therapy. The study will consist in three periods: The first period will address the efficacy of the PrismaLung device at tidal volume of 6 and 4 ml/kg PBW using an off-on-off design. The second part of the study will investigate the effect of varying the sweep gas flow and the mixture of the sweep gas on the CO2 removal rate (random order). The third part will compare three ventilatory strategies applied in a cross-over design : Minimal distension: Tidal volume 4 ml/kg PBW and positive end-expiratory pressure (PEEP) based on the ARDSNet PEEP/FiO2 table (ARMA). Maximal recruitment: 4 ml/kg PBW and PEEP adjusted to maintain a plateau pressure between 23 - 25 cmH2O. Standard: Tidal volume 6 ml/kg and PEEP based on the ARDSNet PEEP/FiO2 table (ARMA). Each strategies will be apply in a random order for a duration of 22 hours. Pulmonary inflammatory and fibrosis pathway will be assess before and after each period using bronchoalveolar lavage (BAL) samples. Systemic inflammatory cytokines will also be investigate. Main measurements will include respiratory mechanics, transpulmonary pressure, work of breathing, end-expiratory lung volume and tidal ventilation using electrical impedance tomography.
