Upper GI function in sleeping infants.

W E Berquist, M E Ament

    The American Review of Respiratory Disease
    |May 1, 1985
    PubMed
    Summary
    This summary is machine-generated.

    Gastroesophageal reflux (GER) occurs less frequently during sleep in infants and adults. Intraesophageal pH monitoring helps link pulmonary symptoms to GER, with infant GER mechanisms possibly involving sphincter relaxation or abdominal pressure.

    Area of Science:

    • Pediatric Gastroenterology
    • Sleep Medicine
    • Diagnostic Technology

    Background:

    • Intraesophageal pH monitoring provides insights into infant upper gastrointestinal function during sleep.
    • Variability exists in probe placement and control values across studies.
    • Data on feeding acidification and probe position are inconsistent.

    Purpose of the Study:

    • To summarize current understanding of gastroesophageal reflux (GER) in infants during sleep.
    • To highlight the utility of intraesophageal pH monitoring in correlating GER with symptoms.
    • To explore potential mechanisms of GER in infants and advocate for standardized monitoring.

    Main Methods:

    • Review of existing data from intraesophageal pH probe studies in infants and adults.

    Related Experiment Videos

  • Analysis of reflux frequency, duration, and temporal relationships with symptoms.
  • Discussion of potential mechanisms underlying infant GER.

    • Main Results:

    • Asymptomatic GER occurs throughout the 24-hour period but is less frequent and shorter during sleep for both infants and adults.
    • Sleep reflux scores are slightly higher in infants than adults.
    • Intraesophageal pH monitoring can establish a temporal link between pulmonary symptoms and GER episodes.

    Conclusions:

    • Infant GER mechanisms may involve inappropriate lower esophageal sphincter relaxation or increased intra-abdominal pressure, rather than solely low sphincter pressure.
    • Further research into GER mechanisms and standardization of pH monitoring techniques are crucial.
    • Standardization should encompass probe position, meals, scoring, patient position, and monitoring intervals.
