Effect of Amniotic Fluid Odor on Newborn Adaptation and Stress (AFO-NAS)

Aydin Adnan Menderes University70 enrolled

Overview

This study aims to determine whether exposure to the odor of a newborn's own amniotic fluid affects postnatal adaptation and stress in healthy newborns born by cesarean section. Newborns will be randomly assigned to either an intervention group or a control group. Newborns in the intervention group will be exposed to a sterile material moistened with their own amniotic fluid, while newborns in the control group will be exposed to a sterile material moistened with distilled water. Postnatal adaptation, physiological responses, and stress levels will be evaluated at predetermined time points.

Postnatal Adaptation and Stress in Healthy Newborns Born by Cesarean Section

Interventions

In the intervention group, healthy newborns born by cesarean section will be exposed to the odor of their own amniotic fluid shortly after birth. Amniotic fluid collected during delivery will be applied to a sterile material and positioned near the newborn's nose without direct contact with the skin or airway. The intervention will be administered according to a standardized study protocol. The newborns' postnatal adaptation, physiological parameters, and stress responses will be assessed at predetermined time points.

Inclusion Criteria: * Newborns delivered by cesarean section at 38-42 weeks of gestation * Absence of a maternal history of high-risk pregnancy, including eclampsia, preeclampsia, or gestational diabetes Exclusion Criteria: * Birth weight below 2,500 g * Birth weight of 4,000 g or above * Apgar score below 7 at either 1 or 5 minutes after birth * Presence of a congenital anomaly * Admission to the neonatal intensive care unit during the early postnatal period

Outcomes

Primary Outcomes

Heart Rate:beats per minute

The newborn's heart rate will be measured using a pulse oximeter and recorded as beats per minute. Heart rate values will be compared between the amniotic fluid odor group and the sterile distilled water odor group.

Time frame: At 30 minutes after birth

Respiratory Rate: breaths per minute

The newborn's respiratory rate will be assessed by counting respiratory movements for one minute and recorded as breaths per minute. Respiratory rate values will be compared between the study groups.

Time frame: At 30 minutes after birth

Peripheral Oxygen Saturation:percentage

The newborn's peripheral oxygen saturation will be measured using a pulse oximeter and recorded as a percentage. Oxygen saturation values will be compared between the study groups.

Time frame: At 30 minutes after birth

Body Temperature: degrees Celsius

The newborn's body temperature will be measured using a digital thermometer and recorded in degrees Celsius. Body temperature values will be compared between the study groups.

Time frame: At 30 minutes after birth

Secondary Outcomes

Neonatal Stress Level

Neonatal stress will be assessed using the Neonatal Stress Scale developed by Ceylan and Bolışık. The scale consists of eight subgroups: facial expression, body color, respiration, activity level, consolability, muscle tone, extremities, and posture. Each subgroup is scored from 0 to 2, resulting in a total score ranging from 0 to 16. A score of 0 indicates no stress, and higher scores indicate a higher level of neonatal stress and therefore a worse outcome.
