1274例体外受精-胚胎移植治疗分娩新生儿结局分析

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.

Neonatal outcomes of pregnancy resulting from in vitro fertilization and embryo transfer: analysis of 1274 cases

Objective To evaluate the neonatal outcomes of pregnancies resulting from in vitro fertilization and embryo transfer (IVF-ET) in relation to the occurrence of congenital malformations of the neonates. Methods A total of 1274 infants born after IVF-ET were reviewed. The neonatal outcome was evaluated based on gestational weeks, body weight, congenital malformations, manner of spermatization, maternal age and multiple gestation. Results IVF-ET resulted in 930 deliveries, giving birth to a total of 1274 newborns. Spontaneous delivery occurred in 115 cases (12.37%), with preterm birth in 224 cases (24.09%). Among these newborns, 363 (28.49%) had very low born weight (VLBW), 13 (1.02%) had congenital malformations, and neonatal mortality occurred in 15 cases (1.18%). Conclusion IVF increases the risks of twin pregnancies, preterm birth and VLBW, but does not increase the rate of congenital malformations and neonatal mortality. Intracytoplasmic sperm injection (ICSI) is at higher risk of congenital malformations. Maternal age and twin pregnancies are not associated with congenital malformations. IVF can be safe for treatment of infertility.
