【摘要】：目的·研究胎兒估計體質(zhì)量(EFW)差異與新生兒出生體質(zhì)量(BW)差異間的關(guān)系,評估超聲預測雙胎妊娠的新生兒出生體質(zhì)量差異(?BW)的準確性。方法·應用超聲檢測不同孕周雙胎的生長參數(shù),對各項參數(shù)進行統(tǒng)計學分析,探討EFW差異(?EFW)與?BW之間的關(guān)系。結(jié)果·在277對雙胎中,44對雙胎(15.9%)存在2個胎兒?BW≥20%。該現(xiàn)象在雙絨毛膜雙羊膜囊雙胎(DCDA)與單絨毛膜雙羊膜囊雙胎(MCDA)的發(fā)生率分別為68.2%和31.8%,兩者差異無統(tǒng)計學意義(P0.01)。與孕期其他孕周評估的?EFW相比,分娩前末次超聲評估的?EFW與?BW一致性最佳。在MCDA中,孕22~24周超聲評估?EFW的陰性預測值最高(94%)。結(jié)論·雙胎妊娠胎兒出生前末次超聲評估的?EFW與?BW的一致性最高。對超聲未發(fā)現(xiàn)?EFW較大即?EFW20%的雙胎,尤其是孕22~24周階段MCDA中?EFW20%者,其未來發(fā)生選擇性宮內(nèi)生長受限(s IUGR)機會較小。
[Abstract]:Objective to study the relationship between fetal estimated body mass (EFW) and neonatal birth weight (BW), and to evaluate the accuracy of ultrasound in predicting neonatal birth weight difference (BW) in twin pregnancy. Methods the growth parameters of twins of different gestational weeks were measured by ultrasound, and the relationship between EFW difference (EFW) and BW was analyzed statistically. Results in 277 pairs of twins, 44 pairs (15.9%) had two fetal BW 鈮，
