早产儿液态配方奶对生长指标的影响

目的探讨新生儿重症监护病房(NICU)使用早产儿液态配方奶对生长指标的影响。方法选取2012年1月～2013年12月在芜湖市第一人民医院NICU住院且胎龄<34周的112例早产儿,随机分为对组组和观察组(n=56),对照组使用早产儿配方奶粉喂养患儿;观察组使用早产儿液态配方奶喂养患儿,比较2组喂养后恢复至出生体质量时间,监测2组纠正胎龄40周时身长、体质量、头围等指标的变化。结果观察组恢复至出生体质量时间(8.16±2.14)d,短于对照组(9.66±3.51)d(P<0.05);观察组体质量为(3.8±1.9)kg、身长为(61.0±6.5)cm、头围为(38.5±2.5)cm,均大于对照组体质量为(3.6±1.6)kg、身长为(59.0±8.2)cm、头围为(37.5±3.5)cm(F=5.81,P<0.05)。观察组56例中有10例发生宫外发育迟缓,和对照组相比差异不显著。结论早产儿液态配方奶能加快患儿恢复至出生时体质量,纠正胎龄40周时早产儿液态奶喂养患儿生长占优势。

Objective To explore the inlfuence of feeding liquid formula on growth index of premature infants in my NICU（Neonatal intensive care center）.Methods 112 premature infants（gestational age 〈34 weeks） in my NICU from Jan. 2012 to Dec. 2013 were randomly divided into two groups.The control group were fed preterm formula powder and the observe group were fed liquid formula. The comparison was made of the time of regaining birth weight and the changes of height,weight and head circumference were monitored at 40 weeks of correction age.Results The observation group recovered to body mass was （8.16 ± 2.14） time D, shorter than the control group （9.66±3.51） d （P〈0.05）; observation group were （3.8 ± 1.9kg）, body length （61.0±6.5） cm, head circumference was （38.5±2.5） cm, werehigher than those in the control group weight as （3.6±1.6） kg, body length （59.0±8.2） cm, head circumference was （37.5±3.5）cm （F=5.81,P〈0.05）. The observation group of 56 cases occurred in 10 cases of extrauterine growth retardation, and compared with the control group, the difference was not signiifcant.Conclusions Liquid formula for premature infants can accelerate the time of regaining birth weight. At 40 weeks of correction age,the growth in feeding liquid formula group predominates.
