NICU入院児の成育環境を検討するために、照度環境調整前後の低出生体重児のすいみん行動観察を動画撮影と活動計を用いて、BrazeltonのState判定と生理的反応の特徴を分析した。照度の調整による明らかな変化は認めなかったが、授乳前後の入眠は、授乳から約15分頃前よりState1-2が増えてくることや、周産期医療センター4施設すべてで、米国小児科学会(AAP)基準値を10dB超えていた。全アラームを排除したとしても深夜の静かな時間帯で1.5dB程度の騒音低減効果しか得られなかった。目視によるState判定は個人差があり、観察力教科学習支援を目指し睡眠自動判定装置として画像分析手法を開発中である。
In order to examine the growth environment of cacies in neonatal intensive care units, we observed the sleep behavior of loe-birth-weight babies before and after adjusting the illuminance. We recorded videos of the babies and assessed their state using the neonatal behavioral assessment scale. We also analyzed their physiological responses with a motion watch activity meter. Although no significant change was brought about by the adjustment in illumination intensity, state 1-2 increased by about 15 minutes after breastfeeding, and the sound pressure was 10 dB higher than the standard set by the American Academy of Pediatrics for perinatal centers. Stopping all alarms had only a marginal effect on reducing sound pressure by 1.5 dB in the quiet of midnight. Since the individual differences in visual state judgment led to inaccuracy, we are developing an image analysis method for automatic sleep evaluation equipment to enhance nurses' observation skills.
