oropharyngeal colostrum administration in premature infants

Conditions: Oral Colostrum Administration; Early Feeding Skills; Transition to Oral Feeding

Summary: this study aimed to determine the effect of oropharyngeal colostrum administration on premature newborns on early feeding cues and transition time to full oral feeding.

breastfeeding has immunologic, nutritional, and neurodevelopmental benefits for premature infants. follow-up of premature infants in the neonatal intensive care unit (nicu) for observation and treatment due to immature gestational age, organ or system diseases, and inadequate oral sucking power cause physical and psychological separation of mother and infant, and this is an essential factor leading to breastfeeding failure. despite the abundant evidence in the literature for the benefits of breast milk and especially colostrum for premature infants, breastfeeding and lactation rates are still very low in this vulnerable population due to poor sucking/swallowing/respiratory coordination. although the development of oral feeding skills in premature infants is a challenge for health professionals and parents, oral feeding skills are one of the critical indicators for the discharge of premature infants. although motor activities such as sucking, swallowing, and breathing are known to be present in the prenatal period, it is not known precisely when this coordination is achieved at the earliest after birth. approximately 40% of premature infants have difficulty transitioning from enteral to oral feeding. a systematic review showed that premature infants experience problems with oral feeding in the first four years of life, with a prevalence of 42%. physiological intervention methods that support the transition of premature infants to oral feeding include non-nutritive sucking, oral-motor stimulation, and oral care with colostrum or breast milk. oropharyngeal colostrum administration is an intervention method reported to activate the digestive hormones of minimal enteral feeding, encourage feeding, accelerate the maturation of the gastrointestinal system, and shorten the transition to full oral feeding with positive stimulation. when the literature is examined, it is reported that premature infants fed with colostrum from the nicu also have increased breastfeeding continuity after discharge. the most crucial difference between our study and the studies available in the literature is related to how oropharyngeal administered colostrum affects the infant's early feeding cues (coordination of sucking-swallowing and respiration during feeding) and how much it accelerates/shortens the transition to oral feeding. in the literature, no study is similar to our study examining how oropharyngeal colostrum administration affects this process in the transition to full oral feeding using a measurement tool on the subject.
