AI Article Synopsis

Article Abstract

Background: Bronchopulmonary dysplasia (BPD) is a common complication in very preterm infants. Despite advances in perinatal medicine, the number of BPD patients is increasing in Japan. The aim of this study was to conduct a nationwide survey of the strategies used for the prevention or treatment of BPD.

Methods: Questionnaires assessing the current strategies used to prevent or treat BPD, including neonatal resuscitation, drug therapy, and respiratory supportive care, were sent to secondary or tertiary perinatal units in 2015; responses were compared with those obtained from similar surveys in 2005 and 2010. The annual trend in incidence of BPD among the very low birth weight infants (VLBWIs) was determined using the Neonatal Research Network of Japan database.

Results: The response rates in 2005, 2010, and 2015 were 86.8% (230/265), 64.5% (185/287), and 82.8% (236/285) of units, respectively. The use of patient-triggered ventilation for initial management significantly increased from 50% of units in 2005 to 91% in 2015. By contrast, decreased use of high-frequency oscillatory ventilation (HFOV) from 72% to 65% and that of nasal continuous positive airway pressure from 79% to 68% were reported. The proportion of units where the upper limit of targeted blood oxygen saturation before a diagnosis of BPD was set to ≥95% decreased substantially from 92% to 56% over the 10-year period. Despite these changes in management of BPD, the incidence of BPD among VLBWIs in Japan was increasing over a decade.

Conclusion: This survey demonstrated that there were various changes in practice regarding the prevention or treatment of BPD in Japan. Continuous surveys are required to understand the current clinical situation, and research is needed to develop and evaluate a novel treatment for BPD in premature infants.
