摘要
目的了解世界范围内晚期早产儿的出生情况和流行病学特点。方法计算机检索中国知网全文数据库、万方数据库、维普中文数据库、中国生物医学文献数据库、Medline、Embase英文数据库关于晚期早产儿的研究报道,按照纳入标准筛选出符合要求的文献进行文献分析。结果共有29篇文献纳入研究,现有研究表明,晚期早产儿出生率较高,出生人数逐年增长,主要早产原因有孕妇胎膜早破、各种妊娠并发症、多胎妊娠等。晚期早产儿易发生神经系统、呼吸系统、消化系统并发症和高胆红素血症、感染、低血糖、贫血、体温不稳定等并发症,其中呼吸系统并发症发病率最高。与足月儿相比,晚期早产儿住院时间长、治疗花费高且临床转归情况不理想,甚至有生长发育迟缓的可能性。结论晚期早产儿占早产儿比例大,各系统发育不成熟,较足月儿存在更多的临床问题,是应该得到高度重视的高危人群。
Objective To analyze the worldwide birth rate and clinical characteristics of late preterm infants. Methods Literatures related to epidemiology of late preterm infants were searched electronically from the databases of CNKI, WanFang, Chinese VIP, SinoMed, Medline and Embase, and were selected according to the inclusion criteria. Results A total of 29 literatures met the inclusion criteria. The results showed that the birth rate was higher, the number of births was increasing year by year and premature rupture of membranes, various pregnancy complications and multiple pregnancy were the most common causes of late preterm infants. Clinical problems of late preterm infants included complications of nervous system, respiratory system and digestive system, as well as hyperbilirubinemia, infections,hypoglycemia, anemia and temperature instability. The highest rate of complications was oeeufing in the respiratory system. Compared to term newborns,late preterm infants had longer hospital stay,more treatment cost,poorer clinical outcomes and higher risk for developmental delay. Conclusion Late preterm infants, who are physiologically immature and have more clinical problems than term infants,is in a large proportion of premature infants and should get highly attention.
