Light Reduction Capabilities of Homemade and Commercial Incubator Covers in NICU

Abstract

Reduction of high-risk neonates' exposure to aversive light stimulation is an important component of developmentally supportive care. In neonatal intensive care unit (NICU), usually light is reduced by reducing the room's light level or by using incubator covers. Many types of incubator covers are in use, including homemade and commercial covers. A comparative study was used to determine the light reducing capabilities of 19 homemade incubator covers, 2 commercial covers, and 1 receiving blanket. The covers were tested by covering and uncovering an incubator and an oxygen hood in the NICU during daytime and nighttime lightings. The light reducing capabilities value was determined for each cover using an Extech light dosimeter when the cover was placed over and removed from an oxyhood, and an incubator. The study showed that the light reducing capability of the commercial covers was 91.2%, the homemade covers capability was 72.1%, and the receiving blankets capability was 55.1%. A significant difference between the commercial and homemade covers was found (F = 452.50, P < 0.00). Commercial incubator covers are the most effective covers to achieve light reduction; homemade covers can be effective if made large enough so that they completely cover all sides of the incubator.

Nursing Interventions That Promote Sleep in Preterm Newborns in the Neonatal Intensive Care Units: An Integrative Review

“…Concerning incubator covers, this is already a method instituted by many neonatal intensive care units to minimize the intensity of light affecting newborns [ 42 ].…”

Sensory exposure of neonates in single-room environments (SENSE): an observational study of light

“…The covers used in NICU and SCN are similar to the commercial made incubator covers described by Ludington-Hoe and Abouelfettoh,19 which found an 82%–83% light reduction capability inside the incubator during the day and 75%–93% light reduction overnight. In NICU, the median and IQR for external incubator light were much higher than SCN overall.…”

Breastfeeding Challenges and the Preterm Mother-Infant Dyad: A Conceptual Model

“…2 Although safe and competent oral feeding require mature skills, it is important to remember that oral feeding difficulties can also be of nonoral origins, for example, infant's clinical status at feeding time and during the feeding (e.g., cardiorespiratory status and fatigue), the NICU environment (e.g., light and noise level), infant's own behavioral states (e.g., sleepy, quiet alert, or crying), and/or organization (e.g., calm or agitated).
