Relationship Between Duration of Tube Feeding and Success of Oral Feeding in Preterm Infants

Abstract Objective Primary: to identify the potential relationship between duration of tube feeding and success of oral feeding in preterm infants; secondary: to identify the potential relationships among duration of tube feeding and alert behavioral states, orally directed behaviors, and nutritive sucking. Design A descriptive correlational study. Setting A Level III NICU at an inner-city hospital. Participants Twenty-eight preterm infants who were born between 28 and 32 weeks gestational age, were clinically stable, and were expected to have at least 1 week of tube feeding during their initial hospitalizations. Methods Data were collected daily from participants' electronic medical records and at one-time oral feeding evaluations within 48 hours after the removal of the feeding tube. Results We found a significant negative correlation between duration of tube feeding and oral feeding success (p = .000). We found no correlations between duration of tube feeding and alert behavioral states, orally directed behaviors, or nutritive sucking. Conclusion Although the duration of tube feeding is a nonmodifiable factor, preterm infants who are anticipated to have extended durations of tube feeding may be at risk for delayed oral feeding success.
