Abstract
Introduction: The infants may alter their motor and sleep-wake profile, during a hospitalization due to an acute disease.
Objective: To describe the motor activity profile and sleep-wake cycle of infants hospitalized due to a respiratory disease.
Subjects and Methods: We prospectively evaluated 17 infants, 6-12 months of age, with normal nutritional status, both gender, admitted to a Pediatric Public Hospital, because a low respiratory tract infection and respiratory failure. Starting on the first morning after admission, an actigraph was placed at an ankle for 24 h.; they also were directly watched by one observer, registering hourly: motor spontaneous activity, procedures and sleep. The actigraphic information saved was voided to a computer program and analyzed.
Results: Duration of nocturnal sleep (20-06 h) was 362 min (210-550) and of diurnal sleep (06-20 h) was 213 min (59-268). Range of diurnal activity was 266-779 min and nocturnal activity was 45-300 min.
Conclusions: The actigraphic information is sensible to detect motor activity and evaluation of sleep-wake cycle in hospitalized infants. There is a wide variability between infants in the duration of motor activity and sleep. There is concordance between the actigraphic registration and the direct observation of activity.
