Eye Covering and White Noise During Nasogastric Tube Insertion in Preterm Infants

November 3, 2026 updated by: Ayşegül Şimşek, Marmara University

The Effect of Eye Covering and White Noise During Nasogastric Tube Insertion on Comfort, Pain, Stress, and Physiological Parameters in Preterm Infants

This study aims to evaluate the effects of eye covering and white noise during nasogastric tube insertion on comfort, pain, stress, and physiological parameters in preterm infants. A total of 90 preterm infants will be randomly assigned to one of three groups: eye covering, white noise, or combined eye covering and white noise. Comfort, pain, stress, heart rate, respiratory rate, and oxygen saturation will be assessed before, during, and after nasogastric tube insertion.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

3 days and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Eye Covering

Preterm infants will receive eye covering beginning 15 minutes before nasogastric tube insertion. The eye covering will remain in place during the procedure and for 15 minutes after the procedure.
Other: Eye Covering

Eye covering will be applied 15 minutes before nasogastric tube insertion and will remain in place during the procedure and for 15 minutes after the procedure.
Experimental: White Noise

Preterm infants will receive white noise at 45 dB beginning 15 minutes before nasogastric tube insertion. White noise will continue during the procedure and for 15 minutes after the procedure.
Other: White Noise

White noise at 45 dB will be started 15 minutes before nasogastric tube insertion and will continue during the procedure and for 15 minutes after the procedure.
Experimental: Eye Covering and White Noise

Preterm infants will receive both eye covering and white noise beginning 15 minutes before nasogastric tube insertion. Both interventions will continue during the procedure and for 15 minutes after the procedure.
Other: Eye Covering and White Noise

Eye covering and white noise at 45 dB will be applied together beginning 15 minutes before nasogastric tube insertion. Both interventions will continue during the procedure and for 15 minutes after the procedure.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Neonatal Comfort Level Assessed Using the COMFORTneo Scale
Time Frame: 5 minutes before, during procedure, and 5 minutes after nasogastric tube insertion

Neonatal comfort will be assessed using the COMFORTneo Scale before, during, and after nasogastric tube insertion. COMFORTneo is used to assess comfort and distress in neonates.
5 minutes before, during procedure, and 5 minutes after nasogastric tube insertion

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Neonatal Pain and Stress Assessed Using the ALPS-Neo Scale
Time Frame: 5 minutes before, during procedure, and 5 minutes after nasogastric tube insertion

Neonatal pain and stress will be assessed using the ALPS-Neo Neonatal Pain and Stress Assessment Scale before, during, and after nasogastric tube insertion.
5 minutes before, during procedure, and 5 minutes after nasogastric tube insertion
Heart Rate
Time Frame: 5 minutes before, during procedure, and 5 minutes after nasogastric tube insertion

Heart rate will be measured using a pulse oximeter and recorded as beats per minute.
5 minutes before, during procedure, and 5 minutes after nasogastric tube insertion
Respiratory Rate
Time Frame: 5 minutes before, during procedure, and 5 minutes after nasogastric tube insertion

Respiratory rate will be measured and recorded as breaths per minute.
5 minutes before, during procedure, and 5 minutes after nasogastric tube insertion
Oxygen Saturation
Time Frame: 5 minutes before, during procedure, and 5 minutes after nasogastric tube insertion

Peripheral oxygen saturation will be measured using a pulse oximeter and recorded as a percentage.
