Diagnosis and Management of Gastroesophageal Reflux in Preterm Infants
Insights
Gastroesophageal reflux (GER) is common in preterm infants. Current treatments, including conservative measures and medications, lack proven efficacy and may cause harm, suggesting cautious use in the NICU.
Area of Science:
- Neonatal Medicine
- Pediatric Gastroenterology
Background:
- Gastroesophageal reflux (GER) is prevalent in preterm infants, frequently diagnosed in Neonatal Intensive Care Units (NICUs).
- Significant variability exists in GER treatment protocols across different NICU settings.
Purpose of the Study:
- To examine the physiology, diagnosis, and symptomatology of GER in preterm infants.
- To review current treatment strategies for GER in the NICU.
Main Methods:
- Clinical report synthesizing existing data and clinical observations.
- Analysis of conservative management techniques and pharmacologic interventions.
Main Results:
- Conservative measures like positioning and feeding adjustments show no significant reduction in GER signs.
- Pharmacologic agents, especially gastric acid blockers, have limited efficacy and potential for harm in preterm infants.
Conclusions:
- Current pharmacologic treatments for GER in preterm infants lack robust evidence of benefit.
- The risks associated with pharmacologic interventions suggest they should be used sparingly, if at all.
Abstract:
Gastroesophageal reflux (GER), generally defined as the passage of gastric contents into the esophagus, is an almost universal phenomenon in preterm infants. It is a common diagnosis in the NICU; however, there is large variation in its treatment across NICU sites. In this clinical report, the physiology, diagnosis, and symptomatology in preterm infants as well as currently used treatment strategies in the NICU are examined. Conservative measures to control reflux, such as left lateral body position, head elevation, and feeding regimen manipulation, have not been shown to reduce clinically assessed signs of GER in the preterm infant. In addition, preterm infants with clinically diagnosed GER are often treated with pharmacologic agents; however, a lack of evidence of efficacy together with emerging evidence of significant harm (particularly with gastric acid blockade) strongly suggest that these agents should be used sparingly, if at all, in preterm infants.
