昼夜光照节律护理对早产儿的影响

The Effect of Light Circadian Rhythm Nursing on Premature Infants

目的:研究12 h的黑暗-光照循环对早产儿生长发育的影响。方法:选取本院2015年1月-2017年2月收治的61例早期早产儿,采用随机数字表法将早产儿分为试验组30例和对照组31例。试验组采用暖箱上加盖暖箱罩,给早产儿提供一个12 h的黑暗-光照循环;对照组24 h暴露在自然光和灯光下,对两组早产儿体重、头围、身长和住院天数进行测定并比较。结果:试验组达到全量喂养天数和住院天数均少于对照组,差异均有统计学意义(P<0.05);试验组日均体重增长值、周均身长增长值均大于对照组,差异均有统计学意义(P<0.05);两组周均头围增长情况比较,差异无统计学意义(P>0.05)。结论:给予12 h黑暗-光照交替光线刺激,有助于早产儿尽快形成正常的昼夜生物节律,从而促进早产儿的生长发育,缩短疾病过程。

Objective： To study the effects of 12 hours of darkness and photoperiod on the growth and development of premature infants.Method： From January 2015 to February 2017, 61 premature infants, they were divided into the experimental group （ 30 cases ） and the control group （ 31 cases ） according to the random number table method.The experimental group used warm box affixed on the hood, made a 12 hour light dark cycle; the control group 24 hours exposed to natural light and light, body weight, head circumference, body length and length of hospitalization of two groups were compared.Result： The total amount of feeding days and hospitalization length of the experimental group were less than those of the control group, the differences were statistically significant （ P〈0.05 ） .The average daily weight gain and average length growth of the experimental group were higher than those of the control group, the differences were statistically significant （ P〈0.05 ） ; but there was no significant difference in head circumference growth of two groups （P〉0.05） .Conclusion： 12 hours of dark light and light stimulation is helpful to premature infant form normal circadian rhythm as soon as possible, and promote their growth and development, shorten the course Of disease.
