Infant physiologic and behavioral organization during swaddled versus unswaddled weighing
1Children's Hospital, Denver, Colo, USA.
Insights
Blanket swaddling during weighing significantly reduced physiologic distress and improved behavioral organization in preterm infants. This simple intervention enhances self-regulation and motor skills in vulnerable newborns.
Area of Science:
- Neonatal care
- Infant development
- Pediatric nursing
Background:
- Preterm infants experience significant physiological and behavioral distress during routine care procedures like weighing.
- Effective interventions are needed to minimize stress and support the development of preterm infants in the NICU.
Purpose of the Study:
- To evaluate the impact of blanket swaddling during weighing on the physiological and behavioral responses of preterm infants.
Main Methods:
- A repeated-measures crossover design was employed with 14 preterm infants (mean gestational age 32 weeks).
- Infants were weighed on consecutive nights, either swaddled or unswaddled, in a randomized order.
- Physiological and behavioral responses were assessed using the Assessment of Behavioral Systems Organization scales.
Main Results:
- Swaddled weighing was associated with significantly less physiological distress (p < 0.002).
- Infants demonstrated improved motor organization (p < 0.001) when swaddled.
- Enhanced self-regulatory ability was observed in swaddled infants (p < 0.037).
Conclusions:
- Blanket swaddling during weighing is a potentially effective method to decrease physiological and behavioral distress in preterm infants.
- This practice may support better organization and self-regulation in vulnerable newborns.
Objective:
The objective of this study was to evaluate the use of blanket swaddling during weighing on the physiologic and behavioral responses of preterm infants.
Study Design:
A repeated-measures crossover design was used in a children's hospital intensive care nursery setting. Fourteen preterm infants with a mean gestational age of 32 weeks and mean weight of 1427 gm were weighed on two consecutive nights. A random start approach was used to determine initial order of swaddled or unswaddled weights. Effects of swaddled and unswaddled weighing were examined with use of the Assessment of Behavioral Systems Organization scales. Repeated-measures analysis of variance was used for analysis.
Results:
Contrasts done on significant treatment-period interactions indicated that when swaddled, infants showed less physiologic distress (p < 0.002), better motor organization (p < 0.001), and more effective self-regulatory ability (p < 0.037) than when unswaddled during weighing.
Conclusions:
Swaddled weighing may decrease physiologic and behavioral distress in preterm infants.
