Insights
This study identified key risk factors for bronchopulmonary dysplasia (BPD) in premature infants in Taiwan. Male gender, small for gestational age (SGA), and initial resuscitation methods like endotracheal intubation (ETT) are significant predictors of severe BPD and mortality.
Area of Science:
- Neonatology
- Pediatric Pulmonology
- Perinatal Medicine
Background:
- Bronchopulmonary dysplasia (BPD) is a chronic respiratory condition affecting premature infants.
- Risk factors for BPD can vary geographically, necessitating regional studies.
- Understanding these factors is crucial for developing targeted interventions.
Purpose of the Study:
- To identify risk factors for BPD and BPD/mortality in premature infants in Taiwan.
- To analyze regional variations in BPD risk factors.
- To provide data for focused interventions and future research.
Main Methods:
- Retrospective analysis of 3111 infants with birth weight ≤ 1500 gm or gestational age < 30 weeks.
- Utilized data from the Taiwan Neonatal Network.
- Applied multivariate analysis to identify significant risk indicators for BPD and BPD/mortality.
Main Results:
- Low gestational age (GA) and low birth weight were significant risk factors for BPD.
- For moderate-to-severe BPD, male gender, small for gestational age (SGA), and initial resuscitation (endotracheal intubation or cardiopulmonary cerebral resuscitation) were additional risk factors.
- SGA and initial resuscitation remained key predictors for the moderate-to-severe BPD/death group.
Conclusions:
- Male gender, SGA, and endotracheal intubation or cardiopulmonary cerebral resuscitation are critical risk factors for moderate-to-severe BPD/death in low-birth-weight infants in Taiwan.
- These findings support the need for region-specific BPD prevention and management strategies.
- Further research can build upon these identified risk factors for improved infant outcomes.
Abstract:
Bronchopulmonary dysplasia (BPD) is a major respiratory condition mainly affecting premature infants. Although its occurrence is global, risk factors may differ regionally. This study, involving 3111 infants with birth weight ≤ 1500 gm or gestational age (GA) < 30 weeks, aimed to identify risk factors for BPD and BPD/mortality in Taiwan using data from the Taiwan Neonatal Network. The BPD criteria were based on the National Institute of Child Health and Human Development standards. Average GA was 27.5 weeks, with 23.7% classified as small for GA (SGA). Multivariate analysis highlighted low GA, low birth weight, and other perinatal factors as significant risk indicators for BPD. For moderate-to-severe BPD, additional risk factors included male gender and SGA, endotracheal intubation (ETT) or cardiopulmonary cerebral resuscitation (CPCR) in initial resuscitation. In the moderate-to-severe BPD/death group, SGA and ETT or CPCR in initial resuscitation remained the only additional risk factors. The study pinpoints male gender, SGA and ETT or CPCR as key risk factors for moderate-to-severe BPD/death in low-birth-weight infants in Taiwan, offering a basis for focused interventions and further research.
