Home oxygen promotes weight gain in infants with bronchopulmonary dysplasia
Insights
Home oxygen therapy is crucial for promoting weight gain in infants with bronchopulmonary dysplasia (BPD). Discontinuing oxygen led to growth deceleration, while its resumption improved weight gain, underscoring its importance.
Area of Science:
- Neonatology
- Pediatric Pulmonology
Background:
- Bronchopulmonary dysplasia (BPD) is a chronic lung disease in premature infants.
- Adequate nutrition and oxygenation are vital for growth in infants with BPD.
Purpose of the Study:
- To investigate the impact of home oxygen therapy on weight gain in infants diagnosed with BPD.
- To assess the relationship between oxygen saturation levels and infant growth trajectories.
Main Methods:
- Retrospective analysis of 22 infants with BPD in a home oxygen program.
- Monitoring of transcutaneous oxygen tension (over 55 mm Hg) and/or pulse oximeter oxygen saturation (over 92%).
- Comparison of growth percentiles before and after oxygen therapy adjustments.
Main Results:
- Infants receiving appropriate home oxygen therapy maintained growth percentiles comparable to healthy full-term infants.
- Seven infants who inappropriately discontinued oxygen therapy experienced significant weight gain deceleration.
- Resumption of oxygen therapy improved weight gain, but original growth percentiles were not regained.
Conclusions:
- Home nasal cannula oxygen therapy plays a significant role in promoting weight gain for infants with BPD.
- Consistent adherence to prescribed oxygen therapy is essential for optimal growth outcomes.
- Maintaining adequate oxygenation is critical for preventing growth faltering in this vulnerable population.
Abstract:
To study the effect of oxygen therapy on weight gain in bronchopulmonary dysplasia (BPD), the growth of 22 infants with BPD enrolled in a premature follow-up clinic and home oxygen program was examined retrospectively. Mean gestational age was 28 weeks (range, 26 to 33 weeks) and mean birth weight was 1110 g (range, 680 to 2000 g). After discharge, infants were monitored monthly to maintain transcutaneous oxygen tension over 55 mm Hg and/or pulse oximeter oxygen saturation over 92%. With appropriate home oxygen, all 22 infants grew as well as healthy, full-term infants (mean, 40th percentile; range, tenth to 80th percentile) when ages were corrected for prematurity. Parents discontinued oxygen therapy inappropriately in seven infants, and all seven experienced significant deceleration in weight gain. When home oxygen therapy was resumed, their weight gain improved, but the infants never regained their original percentiles during the study period. The 15 infants who continued home oxygen therapy maintained their original weight percentiles throughout the study period. These data support an important role for home nasal cannula oxygen in promoting weight gain in selected infants with BPD.
