本研究は実態調査であり，東京都内地域周産期母子医療センターで出生した早産児14名を対象とした．出生時平均在胎週数は31週1日（25週3日～35週0日），出生時平均体重は1,550g（703g～2,420g），測定時の平均修正週数は36週4日（35週6日～38週5日）であった．調査方法は，散瞳点眼剤ミドリン®Pを点眼した後，点眼する前の瞳孔径に戻るまで，1時間ごとMMI瞳孔計を用いて測定し，散瞳剤の副作用の有無を観察した．その結果，点眼する前の瞳孔径に戻るまでの所要時間は，6時間（中央値）であったが，最長で10時間を要する子どももいた．散瞳剤の副作用は認めなかったが，散瞳中の早産児は光の影響を受けやすく，眩しい状況にさらされる．看護者は，散瞳剤を使用した子どもの瞳孔が元の状態に戻っているか観察すると共に，眩しさやストレスを軽減するような対策が必要である．, The objective of this study was to clarify the time needed for the pupillary diameter to return after the application of a mydriatic agent to the pre-mydriatic level and the presence or absence of adverse effects in premature infants.
A field survey was carried out concerning 14 premature infants born at perinatal medical centers in Tokyo. Their mean gestational age at birth was 31 weeks and 1 day (range, 25 weeks and 3 days-35 weeks and 0 days), mean birth weight was 1,550g (range, 703g-2,420g), and corrected gestational age at measurement was 36 weeks and 4 days (range, 35 weeks and 5 days-38 weeks and 5 days). The mydriatic eye solution Mydrin®-P was applied to the eyes, the time until the pupillary size returned to the pre-mydriatic level was measured at 1-hour intervals using an MMI pupillary diameter meter, and the presence or absence of adverse effects of the mydriatic agent was examined. While the median time needed for the pupillary diameter to return to the pre-mydriatic level was 6 hours, a maximum of 10 hours was needed in some infants. Although no adverse effect of the mydriatic agent was noted, premature infants during mydriasis were susceptible to the effects of light and are exposed to glare. In infants after the application of a mydriatic agent, nurses must examine whether the pupil has returned to the normal size and take measures to alleviate the glare and stress.},
