Abstract
The stress of treatments in the neonatal intensive care unit (NICU) has been considered to affect autonomic nerve activity and motions in premature infants. In order to improve the treatments in NICU, we surveyed the actual environment in NICU, quantitatively. In this paper, we measured heart rate (HR) and motions of 8 premature infants at 4 types of stimuli according to the care in NICU. As the results, we clarified that physiological response was different depending on the kind of stimulation. We found that the motion by stimuli was different depending on the premature infants, from the analysis of motions. Therefore, motions by stimulation were different in each premature infant. Importance of treatment according to individual premature infants was suggested.
