Effect of standard rest periods on convalescent preterm infants.

Journal Article

To examine the effects of standardized rest periods on the sleep-wake states of preterm infants who were convalescing.A randomized experimental study conducted from time of infants' entry into intermediate care until their discharge from the hospital. Because subjects' time in this study varied, data were analyzed cross-sectionally using the observation made between 5-11 days of the study and longitudinally over 3 weeks using a subset of subjects.The intermediate care nursery of a tertiary care hospital.Forty-six preterm infants (23 matched pairs). A subset of 12 pairs, in which infants in the experimental and the control groups were in the study for 3 weeks, was analyzed longitudinally.Four standardized rest periods each day.Infants were observed once a week between noon and 8 p.m. Three sleep-wake states--quiet awake, active, and sleep--were measured as percentages of the naps and total observation.Within 5 days, infants in the experimental group exhibited more sleep (F[1,44] = 2.37, p < 0.05) and less active states (F[1,44] = 3.06, p < 0.01) during nap time. Infants receiving the intervention for 3 weeks had more sleep (F[1,22] = 4.63, p < 0.05) and less quiet waking states (F[1,22] = 13.85, p < 0.01) during naps. State patterns over the entire observation did not differ between the groups at 5 days, but by 3 weeks, infants in the experimental group had less quiet waking (F[1,22] = 17.44, p < 0.001) and longer uninterrupted sleep bouts (F[1,22] = 5.19, p < 0.05).A simple modification of nursing care had an impact on the sleeping and waking states of preterm infants.
