Respiratory distress syndrome (RDS) due to surfactant deficiency is the most common cause of respiratory failure in preterm infants. Tremendous progress has been made since the original description that surfactant deficiency is the major cause of RDS. Surfactant therapy has been extensively studied in preterm infants and has been shown to significantly decrease air leaks and neonatal and infant mortality. Synthetic and animal-derived surfactants from bovine as well as porcine origin have been evaluated in randomized controlled trials...

Many infants who develop bronchopulmonary dysplasia (BPD) are born with serious respiratory distress syndrome (RDS), which is associated with impaired vascular and alveolar growth. RDS is a breathing disorder that mostly affects preterm infants and occurs in infants whose lungs have not yet been fully developed. The use of surfactant in RDS treatment does not necessarily prevent BPD. Endothelial progenitor cells (EPCs) may contribute to lung angiogenesis for the prevention and treatment of BPD. The aim of this study was to evaluate the therapeutic efficacy of phototherapy for EPC release in preterm infants born with RDS...

Advances in the management of respiratory distress syndrome (RDS) ensure that clinicians must continue to revise current practice. We report the third update of the European Guidelines for the Management of RDS by a European panel of expert neonatologists including input from an expert perinatal obstetrician based on available literature up to the beginning of 2016. Optimizing the outcome for babies with RDS includes consideration of when to use antenatal steroids, and good obstetric practice includes methods of predicting the risk of preterm delivery and also consideration of whether transfer to a perinatal centre is necessary and safe...

In preterm neonates, the use of invasive ventilation may be mandatory because of respiratory distress syndrome (RDS). In this short communication, we demonstrate that invasive ventilation in this susceptible cohort may be associated with episodes of both hypo- and hypercapnia, and that inadequate ventilatory support is associated with the occurrence rate of bronchopulmonary dysplasia (BPD; p < 0.05). Also, inadequate mechanical ventilation is aggravated by a shortage of medical staff.

Importance: Heated, humidified high-flow nasal cannula (HHHFNC) has gained increasing popularity as respiratory support for newborn infants thanks to ease of use and improved patient comfort. However, its role as primary therapy for respiratory distress syndrome (RDS) of prematurity needs to be further elucidated by large, randomized clinical trials. Objective: To determine whether HHHFNC provides respiratory support noninferior to nasal continuous positive airway pressure (nCPAP) or bilevel nCPAP (BiPAP) as a primary approach to RDS in infants older than 28 weeks' gestational age (GA)...

UNLABELLED: Neurally adjusted ventilatory assist (NAVA) improves patient-ventilator synchrony during invasive ventilation and leads to lower peak inspiratory pressures (PIP) and oxygen requirements. The aim of this trial was to compare NAVA with current standard ventilation in preterm infants in terms of the duration of invasive ventilation. Sixty infants born between 28 + 0 and 36 + 6 weeks of gestation and requiring invasive ventilation due to neonatal respiratory distress syndrome (RDS) were randomized to conventional ventilation or NAVA...

OBJECTIVE: To estimate whether antenatal corticosteroids before 34 weeks of gestation are associated with reduced incidence of respiratory distress syndrome (RDS) and composite neonatal morbidity in preterm twins. METHODS: This was a secondary analysis of a multicenter randomized trial for the prevention of preterm birth in multiple gestations. All liveborn, nonanomalous twins delivered between 24 0/7 and 36 6/7 weeks of gestation were included. Neonatal outcomes were compared between women who received antenatal corticosteroids and those who did not...

UNLABELLED: Lung recruitment during high-frequency ventilation (HFV) in preterm infants with respiratory distress syndrome (RDS) has been associated with an increased risk of lung hyperinflation and air leaks. Individualizing the lung recruitment procedure to the severity of lung disease of each patient might reduce these risks. In this prospective cohort study, we evaluated chest X-ray (CXR) characteristics during individualized oxygenation-guided lung recruitment with HFV in preterm infants with RDS, before and after surfactant therapy...

BACKGROUND: Nitric oxide (NO), synthesized from the amino acid L-arginine by the action of NO synthases (NOS), is a pulmonary vasodilator. Asymmetric dimethylarginine (ADMA) is an endogenous inhibitor of NOS. Preterm infants have higher plasma ADMA concentrations than term infants which could cause inhibition of NO synthesis and deterioration in pulmonary functions. We aimed to investigate the relationship between serum ADMA and L-arginine levels of preterm infants and respiratory distress syndrome (RDS), requirement of surfactant treatment, duration of mechanical ventilation, oxygen treatment, and development of bronchopulmonary dysplasia (BPD)...

OBJECTIVE: To examine the outcomes of births among small and appropriate for gestational age (SGA and AGA) infants by gestational age and maternal characteristics. MATERIALS AND METHODS: We used a national perinatal registry to compare the selected maternal and neonatal outcomes between AGA and SGA neonates born at gestational age groups 33-36, 30-32, 28-29, and <28 weeks. We evaluated maternal body mass index (BMI), pre-gestational/gestational diabetes, hypertensive disorders, and cesarean births as well as frequencies of 5-min Apgar score <7, intraventricular hemorrhage (IVH), respiratory distress syndrome (RDS), the need for assisted ventilation, and early neonatal deaths...

BACKGROUND: Respiratory distress syndrome (RDS) is considered one of the major contributors to severe pulmonary dysfunction and consequent death in preterm infants. Despite widespread improvements in care, including increased utilization of antenatal steroids, use of surfactant replacement therapy, and advances in conventional mechanical ventilation (CMV), chronic lung disease (CLD) occurs in 42% of surviving preterm infants born at less than 28 weeks gestational age (GA). High frequency ventilation (HFV) aims to optimize lung expansion while minimizing tidal volume (Vt) to decrease lung injury...

OBJECTIVE: To investigate the neonatal outcomes of twin pregnancies delivered at late-preterm versus term gestation based on chorionicity and indication for delivery. STUDY DESIGN: This is a retrospective cohort study of women with twin pregnancies delivered at ≥34 weeks of gestation from 1995 to 2014. Subjects were categorized into two groups according to gestational age at delivery: late-preterm group (34-36 weeks) and term group (≥37 weeks). Neonatal outcome measures including neonatal intensive care unit (NICU) admission, mechanical ventilator support, and respiratory distress syndrome (RDS) were compared between the late-preterm and term group based on chorionicity (monochorionic or dichorionic) and delivery indication (elective or non-elective)...

Surfactant replacement therapy (SRT) has been shown to reduce mortality and air leaks in preterm neonates from high-income countries (HICs). The safety and efficacy of SRT in low- and middle- income countries (LMICs) have not been systematically evaluated. The major objectives of this review were to assess the (1) efficacy and safety, and (2) feasibility and cost effectiveness of SRT in LMIC settings. We searched the following databases-MEDLINE, CENTRAL, CINAHL, EMBASE and WHOLIS using the search terms 'surfactant' OR 'pulmonary surfactant'...

BACKGROUND: Late preterm delivery (74% of all preterm births) increases the incidence of respiratory pathology, namely respiratory distress syndrome (RDS), transient tachypnea of the newborn (TTN) and the need of ventilator support when compared to term delivery. The aim is to evaluate the respiratory morbimortality in late preterm infants and the risk factors associated with RDS and TTN. METHODS: Descriptive retrospective study of all newborns of 34+0 to 36+6 weeks of gestational age, born at our centre between September 1, 2012 and August 31, 2015...
