摘    要:目的探讨三胎妊娠的胎儿发育规律及适宜分娩孕周。方法回顾性分析中国医科大学第二临床学院1998年11月至2007年3月收治的29例三胎妊娠的胎儿超声测量结果、妊娠期限等。结果三胎妊娠自28孕周以后发育平均双顶径值较单胎小2.42mm(t=6.43,P〈0.01),平均股骨长较单胎小3.1mm(t=8.710,P〈0.01),平均出生体重明显低于单胎同孕周平均值(t=7.25,P〈0.01),平均分娩周数为(34.0±1.5)周。结论三胎妊娠与单胎妊娠的发育规律不同,其新生儿出生体重明显低于单胎,平均分娩孕周较单胎明显缩短。

Abstract:Objective to investigate the patterns of the fetal development and the best gestational weeks for delivery in triplets.Methods We retrospectively analyzed the gestational weeks and fetal developments measured by ultrasound in 29 triplet pregnancies in Shengjing Hospital of China Medical University from the November,1998 to the March,2007.Results The speed of the fetal development slowed down at the beginning of the 28th gestational week.The mean BPD was 2.42mm shorter and the mean FLwas 3.1mm shorter than those in singleton pregnancy.The birth weight of newborns was lower than that in singleton infants.The average delivery gestational week was significantly shorter than that of singleton ones.Conclusion The patterns of the fetal development of the triplets are different from those of singleton pregnancies.Compared to singleton pregnancies,the fetus of the triplet pregnancies is obviously lightweight,and the deliveries are brought forward.
