Reduction of sleep apnea and bradycardia in preterm infants on oscillating water beds: a controlled polygraphic study
Insights
Gently oscillating water beds significantly reduce apnea in preterm infants. This intervention was most effective in reducing prolonged apneic episodes and those linked to bradycardia during specific sleep states.
Area of Science:
- Neonatology
- Pediatric Sleep Medicine
- Respiratory Physiology
Background:
- Apnea of prematurity is a common concern in preterm infants.
- Previous research suggests oscillating water beds may mitigate apneic events.
Purpose of the Study:
- To polygraphically assess the efficacy of oscillating water beds in reducing apnea in preterm infants.
- To extend previous findings on the benefits of oscillating water beds for premature infants.
Main Methods:
- Polygraphic recordings of sleep and respiratory patterns for 24 hours in eight apneic preterm infants.
- Infants served as their own controls, alternating between standard and oscillating water beds in 6-hour blocks.
- Analysis focused on apnea reduction, duration, and association with bradycardia across different sleep states.
Main Results:
- Significant reduction in apnea was observed when infants were on oscillating water beds.
- The longest apneic periods and those with severe bradycardia showed the greatest reduction.
- Apnea reduction was most consistent during indeterminate sleep and most pronounced during quiet sleep.
- Central, obstructive, and mixed apneas were reduced approximately equally.
Conclusions:
- Gently oscillating water beds are effective in reducing apnea of prematurity.
- The intervention demonstrates particular benefit in mitigating prolonged and severe apneic events.
- Oscillating water beds represent a promising non-pharmacological approach for managing apnea in preterm infants.
Abstract:
The sleep and respiratory patterns of eight apneic preterm infants were polygraphically recorded for 24 hours. This polygraphic study was designed to test and extend our previous finding that gently oscillating water beds reduce apnea in premature infants. The infants who ranged in gestational age from 27 to 32 weeks and in birth weight from 1,077 to 1,650 gm served as their own controls, off and on the water bed. The 24-hour recordings were divided into four time blocks with the infant being placed on the water bed during alternate six-hour periods. Apnea was significantly reduced while the infants were on the oscillating water beds, with the longest apneic periods and those associated with severe bradycardia being reduced the most. Reduction of apnea was most consistent during indeterminate sleep and most pronounced during quiet sleep. Short respiratory pauses and periodic breathing were not significantly reduced. Reductions of central, obstructive, and mixed apneas were approximately equal.
