Swaddling: a traditional care method rediscovered

Abstract

Background: This study was undertaken to compare the sleep profiles of healthy infants in swaddling and sleeping bag conditions.

Methods: Polysomnographs of 85 healthy infants (40 in the study group, 45 in the control group) with a mean age of 7.5 weeks were recorded in the sleeping laboratory. A positive decision from the local Ethics Committee and the written consent of the parents were obtained for the study.

Results: Swaddling significantly reduces the rate of spontaneous waking (events/h: 1.39 [0.85-2.77] vs. 2.81 [1.49-4.53], P=0.020) and the number of sleep stage changes (events/h: 3.82 [2.97-5.16] vs. 5.37 [3.58-6.67], P=0.015). Swaddling promotes quiet sleep (36.37% [29%-40.31%] vs. 30.2% [24.45%-36.78%], P=0.032), the time spent awake was decreased (8.98% [4.62%-14.25%] vs. 14.17% [9.2%-18.94%], P=0.001) and sleep efficiency was increased (91.02% [85.75%-95.38%] vs. 85.83% [81.06%-90.8%], P=0.001).

Conclusion: Swaddling promotes a more quiet sleep in infants.
