Brief Summary

This study was planned to evaluate the effect of "feeding model with chronobiologic approach" on circadian rhythm, growth and physiologic parameters of newborns.

Detailed Description

The newborn period is a period when all babies need their basic needs to be met and all babies are very sensitive physiologically, neuro-biologically and psycho-emotionally, but the newborn period is also a very important period in the development of circadian rhythm. It is important to establish a healthy sleep pattern for the formation of the circadian rhythm and the continuation of the functions of all other systems, especially the central nervous system. Formation of circadian rhythm in newborns; It shows a better development in the first 3 months with the effect of environmental factors such as nutrition, light, mother-baby interaction. Breast milk is a nutrient for the growth and development of babies, in addition, breast milk plays an active role in the formation of the baby's circadian rhythm by transmitting information about the time of day to the babies through components such as hormones and immune elements. In cases where breastfeeding is not possible, it is thought that the delivery of expressed breast milk to the babies simultaneously with the "feeding model with a chronobiological approach" has important effects on the sleep-wake cycle and growth and development. In studies examining circadian rhythm in newborns in the world and in our country, the limited number of studies evaluating the relationship between circadian rhythm and breast milk draws attention and further studies are recommended. However, there is no published study evaluating the effect of simultaneous administration of breast milk to the infant in line with the "feeding model with chronobiologic approach" on circadian rhythm, growth and physiologic parameters of newborns.

Primary Outcome Measures
NameTimeMethod
Newborn Circadian Rhythm Follow-up ChartFirst measurement -up the end of the first day circadian rhythm measurements

At the end of 3 days, the records of the duration of the babies' being in "Wakefulness, REM, N-REM / EVRE I, N-REM / EVRE II, N-REM / EVRE III, N-REM / EVRE III, N-REM / EVRE IV" measured by Bispectral Index (BIS) in 5-minute periods within a 24-hour time cycle will be taken from the BIS monitor records and entered into the "Newborn Circadian Rhythm Follow-up Chart" created by the researcher.

Newborn Introductory Information FormFirst measurement - Before the study (before randomization)

The form prepared by the researcher in line with the literature (Galland et al., 2012; Huang et al., 2021; Caba-Flores et al., 2022) consists of questions including the obstetric characteristics of the infant such as gender, gestational-postnatal age, type of delivery, APGAR scores, birth weight, height, head circumference, and the current clinical status of the infant such as diet, comorbidity, and total number of hospitalization days. The questionnaire form was sent to 5 academicians specialized in Pediatric Nursing, their expert opinions were obtained, and the questionnaire form was finalized by making the necessary changes in line with their suggestions. Information about the newborns in the control and experimental groups was collected by the researcher through the "Newborn Introductory Information Form" before the study, hospital records of the newborn and the primary nurse through face-to-face interview method will be collected in about 5 minutes.

Newborn Growth and Physiologic Parameters Follow-up ChartFirst measurement - up the end of the first day night and day measurements

"Temperature (°C), Pulse Rate (min), Blood Pressure (mmHg), Respiratory Rate (min), O2 Saturation (mmHg) will be recorded for 3 days during the day-night cycle of the infants followed in both groups. Physiologic parameters will be measured 1 hour after the 2nd daytime feeding and 1 hour after the 2nd nighttime feeding (i.e. after the baby's 6th feeding). The amount of breast milk received by the infant (ml)" will be monitored for three days separately in the daytime (06:00-17:59) and nighttime (18:00-05:59) cycle. In addition, the infants will be followed up in terms of "Body Weight (g), Height (cm), Head circumference (cm), Persentile" values until the infants are discharged from the hospital and all these parameters will be recorded through the "Newborn Growth and Physiological Parameters Follow-up Chart" created by the researcher.
