PURPOSE: The aim of the study was to compare the advantages of semi-elevated (SEP) with side-lying positioning (SLP) during bottle-feeding of preterm infants.~METHOD: The study included forty two neonates (n=42) born ≤34 weeks of gestational age. Four bottle-feeding sessions were tested in each of the newborns: two in the SEP and two in the SLP. The position for the first study was randomly assigned, then positioning changed after each feeding session. In one day, only two consecutive feeding sessions which were included to the study in order to minimize fatigability as a disrupting factor. The levels of saturation (SpO2) and heart rate (HR) were measured as the parameters indicative of the newborn's physiological stability. The factors determining the qualitative aspect of feeding included the total time of declines of SpO2 ≤85%, level of the newborn's alertness according to the Neonatal Behavioral Assessment Scale (NBAS), and the occurrence of choking episodes. The proportion of milk consumed (volume of milk eaten relative to the expected volume) and the duration of the feeding and feeding session were also recorded.
One of the challenges of modern neonatology is to identify the right and effective method that can improve oral feeding. Optimal feeding position may contribute to improving the quality and safety of bottle-feeding in premature infants.
