Effects of waterbed flotation on indicators of energy expenditure in preterm infants
1School of Nursing, West Virginia University, Morgantown.
Insights
Nonoscillating waterbeds reduce energy expenditure in preterm infants. These specialized beds promote longer quiet sleep and fewer state changes, offering a cost-effective intervention for neonatal intensive care units.
Area of Science:
- Neonatal care
- Infant physiology
- Developmental pediatrics
Background:
- Preterm infants in neonatal intensive care units (NICUs) face challenges in regulating energy expenditure.
- Activity level, heart rate, and behavioral state are key indicators of energy expenditure in infants.
- Optimizing the NICU environment is crucial for infant development and well-being.
Purpose of the Study:
- To investigate the impact of nonoscillating waterbeds on energy expenditure in preterm infants.
- To assess changes in activity level, heart rate, and behavioral state associated with waterbed use.
- To determine if waterbed flotation is a viable intervention for reducing energy expenditure in NICU settings.
Main Methods:
- A randomized, counterbalanced crossover study design was employed.
- Twenty-two healthy preterm infants (31-35 weeks postconceptional age) were observed.
- Infants were monitored on a waterbed for 3 days and a standard mattress for 3 days, serving as their own controls.
Main Results:
- Infants spent more time in quiet sleep on the waterbed.
- Reduced active awake and fuss states were observed with waterbed use.
- Fewer state changes and awakenings occurred when infants were on the waterbed, with higher heart rates noted after removal.
Conclusions:
- Nonoscillating waterbed flotation is a simple and cost-effective intervention.
- Waterbeds appear to reduce overall energy expenditure in preterm infants.
- This intervention may contribute to improved physiological stability in the NICU.
Abstract:
The purpose of this investigation was to study the effects of nonoscillating waterbeds on three indices of energy expenditure: activity level, heart rate, and behavioral state. Subjects were 22 healthy preterm infants in a neonatal intensive care unit who had reached 31-35 weeks postconceptional age, and whose average weight was 1,482 grams at the onset of the study. Infants were placed on a waterbed for 3 consecutive days and on a standard incubator mattress for 3 consecutive days. Infants served as their own controls on and off the waterbed. Treatment order was randomly counterbalanced. One-hour observations of activity and state occurring in conjunction with heartbeat counts were the repeated measures on each day over both treatment and control conditions. Infants experienced longer durations of quiet sleep, less active awake and fuss states, and fewer state changes and awakenings while on the waterbed. Heart rates were higher after infants were taken off the waterbed. The findings suggest that nonoscillating waterbed flotation is a simple, cost-effective intervention that reduces energy expenditure.
