摘要
目的评估在新生儿重症监护病房(NICU)中住院的早产儿营养摄入以及体重增加情况,以此对早产儿早期的营养支持决策提供科学指导。方法对从我院NICU出院的93名早产儿,计算其不同阶段的体重增长速度,计算恢复至出生时体重的平均天数,达到推荐摄入标准(RDIs)的平均天数并对出生体重低于1500g组和1500～2000g组进行比较,比较其出生以及出院时体重的百分位数以及积分。结果93名早产儿平均体重增长速度在生后第1周为-4.3g/d,第2周为6.7g/d,整个住院期间为19.1g/d。79名早产儿出现了生理性体重下降,恢复时间为11.1d,达到RDIs的时间为19.0d,低于1500g组所需时间较长。93名早产儿中,出生体重低于第10百分位的占52.3%,而出院时达到79.5%,明显增加;出院时体重百分位数积分(1.81±0.74)分较出生时(2.35±0.78)分有明显的降低。结论早产儿在出生后早期容易出现生长发育落后,出院后有必要坚持治疗,继续强化营养,以实现追赶生长。
Objective To investigate the nutrient intake and the increase of infants＇ body weight in NICU,so as to guide the nutritional support of premature infants. Methods Ninety-three premature infants with body weight between 1 000 - 2 000 g were selected. Average increase of body weight during the first week, the second week and hospitalization period was calculated. We recorded the days needed for regaining their birth weight,and then the days for reaching RDIs. Finally ,we calculated the infants＇ weight percentile and weight percentile scores both on admission and before discharge. Results Average weight gain, 1^st week -4.3 g/d,2^nd week 6.7g/d,hospitalization period 19.1 g/d ;79 cases showed physiological weight losses,mean days needed for regaining initial birth weight was 11.1 d,for all infants to get RDIs was 19.0 d,and 〈 1 500 group needed more days. Percentage of weight lower than 10th percentile at discharge was 79.5% , and it was higher than on admission （52.3%）. Weight percentile score was （ 1.81 ± 0.74） points.it was lower than on admission （2.35±0.78） points. Conclusions Premature infants are prone to develop significant growth retardation before discharge. Special attention should be paid to the nutrition of discharge premature infants to achieve catch -up growth.
