About this study

Official title: The Effect of Amniotic Fluid Odor on Postnatal Adaptation and Stress in Healthy Newborns Born by Cesarean Section

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.

Being tested
Amniotic Fluid Odor Sterile Distilled Water Odor

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Amniotic Fluid Odor Sterile Distilled Water OdorOther

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: At 30 minutes after birth

  2. 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.

    Measured: At 30 minutes after birth

  3. 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.

    Measured: At 30 minutes after birth

  4. 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.

    Measured: At 30 minutes after birth

Secondary outcomes (1)
  1. 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.

    Measured: 30 minutes after birth

Questions about this trial

What is this clinical trial studying?

A study testing Amniotic Fluid Odor Sterile Distilled Water Odor in people with Postnatal Adaptation and Stress in Healthy Newborns Born by Cesarean Section, run by Aydin Adnan Menderes University at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 27 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Heart Rate:beats per minute (time frame: At 30 minutes after birth). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Oct 2026; AzTrials last refreshed its copy on 7 Nov 2026.
