Abstract:
Objective:To investigate the light exposure in neonatal intensive care unit (NICU), and to explore the effect of light management on the growth and development of premature infants.Methods:This study adopted a quasi-experimental research method. Sixty-three premature infants hospitalized in NICU of Obstetrics and Gynecology Hospital Affiliated to Jiangnan University from January to December 2021 were selected by convenience sampling as the control group, and conventional premature infant care measures were implemented, while 60 hospitalized premature infants from January to December 2022 were selected as the observation group, and NICU light management strategies were implemented. The light intensity, bad light exposure, the growth of body mass, body length, hospitalization days of premature infants during hospitalization, and the feeding of premature infants during hospitalization were compared between the two groups.Results:Sixty-three patients were enrolled in the control group, including 28 males and 35 females with a gestational age of (32. 13 ± 1.94) weeks, while 60 patients were enrolled in the observation group, including 32 males and 28 females with a gestational age of (31. 79 ± 1.83) weeks. The daytime and nighttime illuminations in the observation group were (413.79 ± 181.95) and (18.95 ± 12.43) lux, which were better than those in the control group (145.12 ± 99.56) and (53.25 ± 38.34) lux, respectively. The rate of bad light exposure in the observation group was 18.2% (183/1 008). The difference was statistically significant ( t=-29.08, 11.55, χ2=126.99, all P<0.05). In the observation group, the body mass, weekly length gain, hospitalization days, milk intake and age at full feeding on the 7th and 14th day of birth were (1.74 ± 0.32) kg, (1.88 ± 0.32) kg, (1.63 ± 0.60) cm, (26.92 ± 12.32) d, (125.60 ± 69.43) ml/d, (239.33 ± 92.83) ml/d, (15.07 ± 10.01) d, and (1.58 ± 0.31) kg, (1.73 ± 0.31) kg, (1.39 ± 0.48) cm, (32.00 ± 14.00) d, (100.83 ± 68.54) ml/d, (195.05 ± 111.22) ml/d, (18.95 ± 10.76) d in the control group. There were significant differences between the two groups ( t values were -2.89 to 2.13, all P<0.05). Conclusions:The implementation of light management strategy in NICU can effectively reduce the bad light exposure of premature infants, promote their growth and development and shorten the length of hospital stay, which is worthy of clinical application.
