Insights
Gastroesophageal reflux in infants may lead to increased functional residual capacity (FRC), suggesting reduced small airway patency. Airway resistance (Raw) remained normal in this study.
Area of Science:
- Pediatric Pulmonology
- Gastroenterology
- Respiratory Physiology
Context:
- Gastroesophageal reflux (GER) is common in infants and can affect respiratory function.
- Assessing airway mechanics in infants with GER is crucial for understanding potential complications.
Purpose:
- To investigate the relationship between gastroesophageal reflux and airway resistance (Raw) and functional residual capacity (FRC) in infants.
- To determine if GER impacts small airway patency in young children.
Summary:
- Airway resistance (Raw) and functional residual capacity (FRC) were measured using plethysmography in 17 infants (3-12 months) diagnosed with GER.
- No significant elevation in Raw was observed.
- However, 41% of infants exhibited increased FRC per kilogram of body weight, indirectly suggesting diminished small airway patency.
Impact:
- Findings suggest that GER may contribute to subtle changes in lung function, specifically reduced small airway patency, even without overt airway obstruction.
- Highlights the importance of considering respiratory implications in infants with GER.
- Provides data for further research into the mechanisms linking GER and infant respiratory health.
Abstract:
Airway resistance (Raw) and functional residual capacity (FRC pl) were determined by plethysmography in 17 children aged 3 to 12 months. Gastroesophageal reflux was diagnosed on the ground of longterm monitoring of esophageal pH or the X-ray examination of the stomach. No elevated airway resistance was found. In 41% of the cases FRC (per kg of body weight) was increased. This indirectly indicates the diminished small airways patency.
