[Research Presentation] Purpose: Purpose of this study were to investigate the development of sleep-awake rhythms in premature infants and to examine the effect of cycled light on circadian organization and sleep. Methods: A quasi-experimental design was conducted in sick baby room of a medical center of southern Taiwan. Participators were premature infants (>32wks PCA) and without severe medical disease. They were assigned to one of two groups: a control (dimly lighted) group, or an experimental (cycled lighted) group. Continuous sleep-awake states were recorded at before intervention and post-intervention. Background lighting in the nursery rooms was monitored using TES-1332 light meter. Actiwatch-L was placed on the wrist to assess activity. T tests were used for homogeneous analysis of variance. Mixed model was conducted the repeated measures analysis of variance among all groups. Results: Results indicate that the sleep time and the wake time accounts for 70.61% and 29.39% respectively of one day in premature infants of near 37 wks PCA. There no significance of day-nigh differences in sleep-awake patterns. Cycled lighted lasted for longer than one week increased in wake time and decreased in sleep time of day time (8Am-8Pm) for experimental group, but not in the night time (8Am-8Pm).Conclusion: Results of this study indicate the beneficial effects of cycled light on sleep-awake rhythms in premature infant, and provide a basis for sensitive nursing care that incorporates the infant's biological clock.
