Abstract

Background: Placental insufficiency and decreased placental nutrition transfer from the mother to the fetus are the underlying causes of intra-uterine growth restriction (IUGR), a serious and very frequent issue in the perinatal period. Due to a lack of recent research in the area, the current study aims to compare the outcomes of two different feeding strategies for preterm infants with abnormal Doppler readings: early vs. delayed initiation of enteral feeds. Then we implement the better of the two feedings regimens into our standard clinical practice. Objective: The objective of the study was to compare early and late enteral feeding in preterm intrauterine growth restricted neonate to evaluate time to reach full feed, risk of feed Intolerance, weight gain at 10th day of life and length of hospital stays. Study Design: The Randomized Control Trial. Settings: This study was conducted in the neonatology department Tertiary Care Hospital (Nursery MCH Centre, Pakistan Institute of Medical Sciences, Islamabad Pakistan. Duration: 1st June 2022 to 1st December 2022. Methods: The sample was collected from the by non-probability consecutive sampling technique. Babies of any sex who meet the requirements during the first 72 hours of life. A total of 80 newborns were recruited out of them n=40 infants were found as early feeding and n=40 was assigned to late feeding. Demographic and baseline information (admission date, age, gender, gestational age, birth weight) of enrolled neonates recorded in the prescribed proforma. Effects of early or late feeding were monitored daily for 10 days. The outcomes in terms of time to reach full feed, weight gain at 10th day of life and feed intolerance were recorded and compared in both groups. All the information entered on the predesigned proforma by the researcher himself to comply with the study protocol attached. Results: A total of 80 newborns were recruited out of them n=40 infants were found as early feeding and n=40 was assigned to late feeding. The base line characteristics including birth weight, gestational age, respiratory support etc. were not statistically significant. Also, there is no difference of NEC (0.267) and FI (0.312) in early and late feeding groups.  The Cox regression HR: 1.21 (95% CI: 0.829-3.72); p = 0.326). In both groups, the early feeding arm had a shorter median duration by 7 days. Further, the data was compared between early and late feeding group to determined which group is quicker for discontinuation of PN. Conclusion: Our study finds that using the feeding initiation and advancement method and AREDF on Doppler with exclusive breast milk results in faster PN cessation and does not increase the incidence of NEC or FI in preterm IUGR infants between 27 and 33 weeks of age.
