[Comparative study on application of Duo positive airway pressure and continuous positive airway pressure in preterm neonates with respiratory distress syndrome].

Objective: To determine whether early application of Duo positive airway pressure (DuoPAP), in comparison with nasal continuous positive airway pressure (NCPAP), can reduce the need for endotracheal intubation and mechanical ventilation and decrease the incidence of bronchopulmonary dysplasia (BPD) in preterm neonates with respiratory distress syndrome (RDS).

Methods: In a single-center, randomized controlled trial, preterm neonates (gestational ages 30-35 weeks) with RDS were randomly assigned to receive DuoPAP (n=34) or NCPAP (n=33) within 6 hours of birth. If the two noninvasive ventilations were not effective, endotracheal intubation and mechanical ventilation were used, and pulmonary surfactant was administered as rescue therapy.

Clinical characteristics, diagnosis and management of respiratory distress syndrome in full-term neonates.

Background: Respiratory distress syndrome (RDS) is one of the most common causes of neonatal respiratory failure and neonatal death, however, its clinical characteristics are very different from premature RDS, and these characteristics have not been well documented as yet. This study was to investigate the pathogenesis, clinical characteristics and management strategies of RDS in full-term neonates, with the aim of developing a working protocol for improving the outcome in full-term neonates with RDS.

Methods: A total of 125 full-term infants with RDS were enrolled in this study.

[Screening and risk factors analysis of retinopathy of prematurity].

Objective: To analyze the risk factors of retinopathy of prematurity (ROP) and provide evidence for the rational establishment of screening standard.

Methods: The clinical data of 1675 preterm infants at gestational age < or = 36 weeks or birth weight < or = 2500 g who were admitted to the neonatal intensive care unit and had been screened in our hospital from July 2006 to May 2008 were analyzed retrospectively by univariate analysis and Logistic regression analysis. Gender, birth count, gestational age, birth weight, oxygen therapy, and mother's conditions were recorded.
