Brief summary

A randomized clinical study in NAS infants managed via the Eat, Sleep, Console (ESC) approach comparing early weight loss on a standard-caloric density versus high-caloric density feeding regimen.

Detailed description

The aims of the study is to systematically evaluate the benefit of high-caloric diet regimens given to NAS infants in the first three weeks of life. Breastfeeding is the preferred feeding method for NAS infants as it has shown to reduce NAS severity and infant weight loss, though women who are not adherent to drug treatment programs or have the potential to use illicit drugs are not able to breastfeed due to the risks posed to the infant. Several studies have demonstrated the potential for caloric enhancement of formula and breast milk to support weight gain in NAS infants. Through a randomized control trial analyzing infant weight gain on standard-calorie vs. high-calorie diet regimens, we aim to quantify weight patterns in NAS infants and show that increasing caloric intake can improve weight gain.

Design outcomes

Primary

MeasureTime frameDescription
Maximal Percent Weight Loss Compared to Birth Weight2 weeksthis will be measured by twice daily weights while in the hospital and once daily weights at home for two weeks after birth compared with birth weight

Secondary

MeasureTime frameDescription
Median Days to Weight Nadir2 weeksMeasured by determining the days of life that the maximal percent weight loss was obtained for each patient, assessed within the first two weeks after birth
Number of Participants That Return to Birthweight1 monthNumber of participants that regained birthweight, assessed within the first month after birth
Percent Weight Change Per Dayfirst 7 days after birthMeasured by comparing the weight from the weight obtained the day prior, assessed daily for the first 7 days after birth
Length of Hospital Stayup to 6.5 daysMeasured by comparing admission time to discharge time, assessed at hospital discharge
