摘要目的：比较不同方式喂养后早产儿体质量、身高、头围的变化，分析其优劣性。方法选取早产儿260例作为研究对象，按照随机数字表法分为四组，A 组：早产儿配方奶喂养80例；B 组：纯母乳喂养组60例；C 组：普通足月儿配方奶喂养60例；D 组：早产儿配方奶混合母乳喂养60例。所有患儿均在出生后12～24 h 开始喂养。将患儿的体质量、身高、头围以及追赶上足月儿的时间作为评价指标。结果患儿纠正40周胎龄后，B 组体质量、身高、头围均高于其他组，C 组最低，差异有统计学意义（F ＝3．563，P ＜0．05）。纠正胎龄1、3、6个月后，A 组体质量、身高以及头围指标高于其他喂养组，D 组水平次之，C 组水平最低，差异有统计学意义（F ＝3．011、2．853、2．779，均 P ＜0．05）。到6个月时，A 组追赶最快，达到38．8％（31／80），差异有统计学意义（χ2＝29．149，P ＜0．05），其他时段，A 组追赶例数较多，但差异无统计学意义。结论对于早产儿，采用早产儿专用配方奶粉或者早产儿配方奶与母乳的交替喂养的方式优于纯母乳喂养和普通足月儿奶粉喂养，可以在保证患儿的营养需求的同时，缩短追赶足月儿时间，促进婴儿的健康。

abstractsObjective To compare the body weight,height,head circumference of premature babies fed by different ways,and to analyze the advantages and disadvantages.Methods 260 premature infants were selected as the research subjects,according to random number table,they were divided into four groups.Group A:premature infant formula feeding,80 cases;Group B:pure breast feeding group,60 cases;Group C:normal full term formula feeding,60 cases;Group D:premature infant formula mixed breast feeding,60 cases.All children were fed at the first 12 to 24h after birth.The body weight,height,head circumference and catch up full term time were evaluation index. Results After correct gestational age 40 weeks,group B children'weight,height,head circumference were higher than other groups,group C was the lowest levels,the difference was statistically significant (F =3.563,P <0.05).Correct gestational age 1,3,6 months later,group A children'weight,height and head circumference index were higher than other feeding group,the level of group D was the second,the lowest level was group C,the differences were statistically significant (F =3.011,2.853,2.779,all P <0.05).In 6 months,group A,38.8% (31 /80),was the fastest one to reach the full term infant,the difference was statistically significant (χ2 =29.149,P <0.05).At other time,the pur-suing number of group A was bigger,but there was no statistically significant difference.Conclusion For premature babies,preterm infant formula milk powder or premature infant formula and milk feeding way is better than that of pure breast feeding and normal full term milk powder,which can guarantee the children's nutrition demand,shorten the time of pursuing full term infant,promote baby's health.
