Hearing Impairment
Conditions
Brief summary
Before they are born, babies are protected from hearing very loud noises by their mother's bodies. After delivery, they are exposed to many loud noises that are potentially harmful. These noises happen in the neonatal intensive care unit (NICU). The purpose of this research project is to test the fit and the ease-of-use of a new device that may protect infant's hearing in the NICU.
Detailed description
Despite the best efforts of Neonatal Intensive Care Unit (NICU) caregivers, vulnerable and fragile NICU patients are frequently exposed to noxious levels of noise from monitoring and respiratory equipment alarms, as well as from routine NICU care practices. Particularly detrimental to sleep and auditory development are patient exposures to high frequency noises that are specifically designed to alert NICU caregivers to important changes in patient status. This pilot study will help evaluate the fit, ergonomic design and the ease-of-use of a novel hearing protection system (special ear-muffs along with a unique attachment mechanism) specifically designed top diminish the transmission of high frequency noises to patients within the NICU, while allowing some transmission of low frequency sounds, such as a mother's voice.
Interventions
Neonates will be sized and fitted to wear the non-invasive novel hearing protection device over a set period of time in the NICU. Vitals will be monitored.

| Measure | Time frame | Description |
|---|---|---|
| Number of Participants With Skin Erythema After Device Application | Skin erythema was evaluated at the time of device removal after 1 hour of application in phase #1 and after 3 daily 8 hour periods of application in phase #2. | Skin will be assessed for adverse effects such as any device-related adverse events, including evidence of skin redness, rash and/or bruising or discomfort at the site of device application. Skin erythema was described as none, mild, moderate or severe as evaluated by the NICU nursing staff. |

Recruitment details
Patients were recruited from admissions to the neonatal intensive care unit (NICU) in two phases. In phase #1 of the study 25 infants were recruited for participation and 25 infants completed the protocol. In phase #2 of the study 30 additional infants were recruited, with 25 infants completing the protocol. The total number studied was 50.

Outcome results
Number of Participants With Skin Erythema After Device Application
Skin will be assessed for adverse effects such as any device-related adverse events, including evidence of skin redness, rash and/or bruising or discomfort at the site of device application. Skin erythema was described as none, mild, moderate or severe as evaluated by the NICU nursing staff.
Time frame: Skin erythema was evaluated at the time of device removal after 1 hour of application in phase #1 and after 3 daily 8 hour periods of application in phase #2.
Population: Phase #2 data reports the number of participants experiencing erythema at any time after device removal after 3 daily 8 hour periods of device application.
