Background. e purpose of this study of preterm infants was to test the effect of four approaches to the time of transition from
gavage to full oral feedings, time to discharge, and weight gain during the transition. Methods. A randomized experimental design
was used with four intervention groups: early start (32 weeks’ postmenstrual age)/slow progressing experience (gradually increasing
oral feedings offered per day); early start/maximum experience (oral feedings offered at every feeding opportunity); late start (34
weeks’ postmenstrual age)/slow progressing experience; and late start/maximum experience. Results. e analysis included 86
preterm infants. Once oral feedings were initiated, infants in the late start/maximum experience group achieved full oral feeding
and were discharged to home significantly sooner than infants in either early start group. Although not significantly different,
these infants also achieved these outcomes sooner than infants in the late start/slow progressing experience group. ere were
no differences in weight gain across groups. Conclusions. Results suggest starting oral feedings later in preterm infants may result
in more rapid transition to full oral feedings and discharge although not at early postnatal ages. Provision of a more consistent
approach to oral feeding may support infant neurodevelopment and reduce length of hospitalization.
1. Introduction
Although the preterm birth rate has been declined over
the last several years, it continues to hover around 11% [1].
Moreover, despite improved survival of preterm infants and
major changes in their care, many common caregiving issues
remain, including when to initiate and when and how to
advance oral feedings to achieve the best outcomes [2]. us,
the transition from gavage to oral feedings remains a clinical
challenge for both infants and their caregivers. Successful
transition to oral feeding is important as competence at oral
feeding is a criterion for hospital discharge [3]. Delay in
achieving competence at oral feeding is one of the major
reasons for delays in hospital discharge for otherwise phys-
iologically stable preterm infants [4–6].
Achieving oral feeding competence takes time, with the
transition from gavage to all oral feedings reportedly taking
from 10 to 14 days [7]. Although breast feeding may present
fewer physiologic challenges than bottle feeding for the
preterm infant, most preterm infants are bottle fed (formula
or expressed breast milk) at least some of the time while being
in the hospital [8]. us, management of oral feedings for
preterm infants is a key aspect of hospital care. Currently,
there are few evidence-based protocols to guide clinicians
as they assist infants in achieving competence at oral feed-
ing and those that exist are oſten not based soundly on
research evidence. Consequently, already vulnerable infants
are subject to a trial-and-error approach to this most complex
and critical life-sustaining activity, with potentially harmful
short- and long-term effects.
Successfully making the transition from gavage to oral
feedings requires the infant to coordinate suck-swallow-
breathe and maintain autonomic nervous system organi-
zation. Competence at oral feeding requires the infant to
