目的从营养学角度出发,探讨早产儿奶摄入量与坏死性小肠结肠炎(NEC)发生及体质量增长的关系。方法将223例早产儿随机分为2组,对照组逐日每次奶量递增为0.5～1.0ml,观察组按每日20ml/(kg·d)奶量进行个体化喂养。观察在喂养控制摄入情况下,发生坏死性小肠结肠炎的基本情况,及体质量增长情况。结果对照组发生NEC2例,观察组3例,经统计学分析,两组之间NEC发生率无明显差异(P>0.05);观察组体质量增长快及住院天数也明显缩短,差异有统计学意义(P<0.05)。结论根据体质量变化情况制定每日摄入量,不会增加NEC的发生率,但可维持正常体质量的增长,并可以缩短早产儿的住院天数。
Objective To investigate the relationship between milk intake in preterm infants and the occurrence of necrotizing enterocolitis (NEC) and the growth of body mass in terms of nutrition. Methods A total of 223 premature infants were randomly divided into 2 groups. In the control group, the daily milk volume increased from 0.5 to 1.0ml. The observation group was fed individually with 20ml / (kg · d) milk per day. To observe the basic situation of necrotizing enterocolitis in the case of feeding control, and the growth of body weight. Results There were 2 cases of NEC and 3 cases of observation group in the control group. There was no significant difference in the incidence of NEC between the two groups (P> 0.05) by statistical analysis. The body mass growth and hospitalization days in the observation group were also significantly shortened, with statistically significant differences Significance (P <0.05). Conclusion According to the change of body weight, daily intake can not increase the incidence of NEC, but can maintain the growth of normal body weight and shorten the hospitalization days of premature infants.
