NICU (新生児集中治療室) の光環境における早産児のストレス評価

The purpose of this study is to evaluate the stress of premature infant, who is hospitalized in the various lightingenvironment of neonatal intensive care unit, by measurement of physiological responses. We measured the electrocardiogram (ECG) and motion of when the lighting environment changes from 31.5±18.1 to 761.8±219.9 [lux]. The subjects were 8 premature infantsthat were the mean corrected gestational age at the time of evaluation was from 32 weeks to 39 weeks. As the results, we confirmedthat premature infants were influenced by lighting environment in each week and obtained the suggestion of possibility that prematureinfant's inhibitory control system for lighting stimuli after the mean corrected gestational age at the time of evaluation was from 36 to37 weeks.
