Overview
Brief Summary
The purpose of this study is to evaluate sustained lung inflation followed by early nCPAP as delivery room ventilatory management for preterm neonates at risk of respiratory distress syndrome in reducing their need for mechanical ventilation and ameliorating lung injury without inducing adverse effects compared with intermittent bag and mask ventilation.
Detailed Description
Neonatal resuscitation provides lifesaving intervention that, if properly conducted, not only can reduce mortality but probably can significantly decrease subsequent morbidity. Premature infants need appropriate respiratory support and a lung-protective strategy, starting from the delivery room where, on the contrary, an inadequate respiratory approach may influence pulmonary outcome. Mechanical ventilation in the form of positive pressure ventilation has remained the mainstay of treatment of respiratory distress syndrome (RDS) in preterm babies. In recent years, a number of new ventilation strategies have been introduced but the problem of bronchopulmonary dysplasia (BPD) has not been solved. Sustained lung inflation (SLI) lead to a large increase in the tidal volume and the functional residual capacity(FCR) as this intervention may influence the clearance of lung fluids and allow a more even distribution of air throughout the lungs, thus facilitating the formation of FRC. Nasal CPAP and early PEEP act through stabilization and subsequent recruitment of collapsed alveoli, increased FRC resulting in increased alveolar surface area for gas exchange and a decrease in intrapulmonary shunt .also it conserves endogenous surfactant. Previous studies with promising results showed that a combination of sustained lung inflation and early nasal CPAP may be the most effective and least injurious way to recruit the lung in preterm neonates at birth. This study will evaluate sustained lung inflation followed by early nCPAP as delivery room ventilatory management for preterm neonates at risk of respiratory distress syndrome in reducing their need for mechanical ventilation and ameliorating lung injury without inducing adverse effects compared with intermittent bag and mask ventilation.
