Infant apnea: findings on the barium esophagram

Area of Science:

• Pediatric Gastroenterology
• Neonatology
• Pulmonology

Background:

• Apneic episodes and sudden infant death syndrome (SIDS) are critical concerns in infant health.
• Gastroesophageal reflux (GER) is a potential contributing factor to these conditions.

Purpose of the Study:

• To investigate the prevalence of gastroesophageal reflux and other abnormalities in infants presenting with apneic episodes.
• To evaluate esophageal function, anatomy, and gastroduodenal regions in this cohort.

Main Methods:

• Standardized barium esophagrams were performed on 160 infants.
• Assessment focused on swallowing, esophageal and gastroduodenal function, and the level/frequency of gastroesophageal reflux.

Main Results:

• Gastroesophageal reflux was the most frequent abnormality, identified in 54% of infants.
• Nasopharyngeal reflux occurred in 27%, while aberrant right subclavian artery and aspiration were seen in 3% each.
• Swallowing dysfunction, esophageal dysmotility, antral dysmotility, chalasia, and tracheoesophageal fistula were rare (<1%).

Conclusions:

• Gastroesophageal reflux is a highly prevalent finding in infants evaluated for apneic episodes.
• Barium esophagrams are valuable for identifying reflux and other potential causes of apneic episodes in infants.
