A Comparison Study of Feeding Prematures in the Side-lying Position on the Right and Left Side - a Pilot Study.

PURPOSE: The aim of the study is to compare the advantages of side-lying positioning on the right (SLP-R) and left side (SLP-L) of infant's body, during bottle-feeding of preterm infants. METHOD: The study will include eight neonates (n=8) born ≤34 weeks of gestational age. Four bottle-feeding sessions will be tested in each of the newborns: two in the SLP-R and two in the SLP-L. The position for the first study will be randomly assign, then positioning will be change after each feeding session. In one day, only two consecutive feeding sessions will be tested which will be included to the study in order to minimize fatigability as a disrupting factor. The levels of saturation (SpO2) and heart rate (HR) will be measured as the parameters indicative of the newborn's physiological stability. The factors determining the qualitative aspect of feeding include 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 will be record. Maximum time of feeding session will be 40 minutes. Also the posseting during/after feeding and regurgitations will be record in each tested positions.
