Dose-Response Study on Surfactant Nebulization Therapy During Nasal Continuous Positive Airway Pressure Ventilation in Spontaneously Breathing Surfactant-Deficient Newborn Piglets.
The current clinical treatment of neonates with respiratory distress syndrome includes endotracheal intubation and intratracheal instillation of exogenous surfactant. Nebulization of surfactant offers an attractive alternative. The aims of this study were to test nebulization as a noninvasive method of administering surfactant and determine the optimal dose for the treatment of respiratory distress syndrome-associated pathophysiology of the neonatal lungs. ⋯ In newborn piglets with severe bronchoalveolar lavage-induced respiratory distress syndrome, our results demonstrate that the administration of nebulized poractant alfa using an investigational customized eFlow-Neos nebulizer is an effective and safe noninvasive surfactant administration technique.

Early Left Ventricular Dysfunction and Severe Pulmonary Hypertension Predict Adverse Outcomes in "Low-Risk" Congenital Diaphragmatic Hernia.
Given significant focus on improving survival for "high-risk" congenital diaphragmatic hernia, there is the potential to overlook the need to identify risk factors for suboptimal outcomes in "low-risk" congenital diaphragmatic hernia cases. We hypothesized that early cardiac dysfunction or severe pulmonary hypertension were predictors of adverse outcomes in this "low-risk" congenital diaphragmatic hernia population. ⋯ Early left ventricular dysfunction and severe pulmonary hypertension are independent predictors of adverse outcomes among "low-risk" congenital diaphragmatic hernia infants. Early recognition may lead to interventions that can improve outcome in this at-risk cohort.
