目的 分析超早产儿出院至生后1岁体格追赶生长的特点,探讨其追赶生长规律,以指导临床干预工作。方法 选择从2013年8月-2018年4月南方医科大学附属深圳市妇幼保健院成功救治并随访的超早产儿178例(男103例,女75例)进行临床研究。对其出院后至生后 1岁内的体重、身长及头围分别按实际月龄及纠正月龄参照足月儿生长标准进行Z评分评估并分析。结果 超早产儿出院至生后1岁体重、身长和头围均出现追赶性生长,出院至纠正3月龄身长生长速度最慢,纠正4~9月龄头围生长速度最慢。出院后最快的增长阶段在实际月龄4~6月。结论 出院后至生后6月龄内是超早期早产的快速生长期;体重与身长、头围的变化存在不均衡性。
Abstract
Objectives To observe the catch-up growth characteristics of the extremely premature infants from discharge to the age of 1 year after birth,and to explore the growth rhythm of catching up,so as to provide reference for clinical intervention. Methods A total of 178 extremely premature infants (103 males and 75 females) in Shenzhen Maternal and Child Health Hospital were enrolled in this study and were followed up from August,2013 to April,2018. The weight,length and head circumference were evaluated by Z score according to the criterions of actual age and corrected age. Results The extremely premature infants showed catch-up growth in weight,length and head circumference in the first year of life. The growth velocity in length was the lowest within 3 months of correlated age. There was the poorest head circumference growth from 4 to 9 months of correlated age. The best catch-up growth velocity was in the time from 4 to 6 months after birth. Conclusions The fastest catch-up growth period of extremely premature infants is in the time from discharge to 6 months after birth.And there is an imbalance among the growth velocity of weight,tenget and head circumference.
