目的探讨经体外受精-胚胎移植(IVF-ET)治疗分娩的新生儿的情况,以分析IVF-ET技术对新生儿先天畸形的影响。方法对我中心经IVF-ET治疗分娩的1274个新生儿结局进行回顾性分析,探讨新生儿出生孕周、体质量、受精方式、母亲年龄、胎数与先天畸形的关系。结果分娩930例,其中足月产706例(75.91%),早产224例(24.09%)。获新生儿1274个,其中低体质量儿363例(28.49%),新生儿畸形13例(1.02%),围产期死亡15例(1.18%)。结论IVF-ET治疗增加了多胎妊娠、早产、低体质量儿等发生率,但未增加新生儿畸形发生率和围产期死亡率,卵母细胞内单精子注射术新生儿畸形率较IVF高,母亲年龄和胎数与先天畸形无明显关系,IVF-ET是治疗不孕症的安全手段。
Objective To investigate the situation of newborns delivered by IVF-ET in order to analyze the effect of IVF-ET on neonatal congenital malformation. Methods Retrospective analysis of 1,274 newborns treated by IVF-ET in our center was conducted to investigate the relationship between newborns’ birth gestational age, body weight, fertilization methods, maternal age, number of births and congenital malformations. Results 930 cases of childbirth, of which 706 cases of full-term birth (75.91%), premature 224 cases (24.09%). 1274 newborn infants, including 363 cases of low birth weight children (28.49%), neonatal deformity in 13 cases (1.02%), perinatal death in 15 cases (1.18%). Conclusion IVF-ET treatment increased the incidence of multiple pregnancies, premature birth and low birth weight, but did not increase the incidence of neonatal malformations and perinatal mortality. The incidence of deformity in IVF-ET neonates was higher than that of IVF , Mother’s age and number of fetuses and congenital malformations no significant relationship, IVF-ET is a safe method of treatment of infertility.
