, 2005 目的探讨B超测量胎儿双顶径、腹围、股骨长度综合预测胎儿体重的准确性。分析羊水量及不同B超操作者对预测体重的影响。方法回顾性总结2001年在我院分娩的产科病例484例,分娩以前一周内行B超检查并报告有预测体重者,比较预测体重与出生体重间的直接相关关系;应用u检验比较不同羊水量及不同操作者的诊断符合率间的区别。结果预测体重与出生体重的相关系数r分别为:巨大儿组0.904,正常体重组0.859,低体重组0.878,P0.05。结论B超测量胎儿双顶径、腹围、股骨长度综合预测胎儿体重的准确性高 ...

, 1995 在胚胎发育早期，江豚上颌生有短须：左侧１－３根，右侧２－３根。具有半月形外耳廓。雄性胎儿阴茎露于体外。脐带较短。胎儿运动器官（胸鳍、尾鳍和尾柄）发育较快。随着胚胎的发育，外耳廓消失，阴茎藏于体腔。江豚胚胎发育过程中的这些形态学变化，再现了鲸类祖先在陆上生活的历史，同时也反映了鲸类在二次入水过程中所形成的对水环境的适应。此外。通过对收集的１７头江豚胎儿资料进行统计，结果表明长江江豚胎儿的生长速度约为９．０８ｃｍ／月（Ｏ．３０３ｃｍ／ｄ），妊娠期为９．４个月，交配季节为６－８月份，分娩为３ ...

, 1997 摘 要 将胎儿窘迫60 例随机分为甲、乙两组, 每组30 例。甲组给予氨茶碱0. 25 g 加入葡萄糖液缓慢 静脉推注, 乙组用维生素C、维生素K1 加入葡萄糖液静脉推注。用药前后观察胎心情况、羊水情况,新生儿出生 后行脐血血气分析及新生儿Apgar评分。结果显示: 用药后甲组胎心改善率为79% ,乙组为48% (P < 0. 05) ; 血 pH< 7. 2者,甲组为25% ,乙组为42% ; 平均PCO2 甲组为5. 98% k Pa,乙组为7. 57k Pa( P < 0.

Zhongguo shiyan zhenduanxue, 2018 胎儿宫内生长受限(FGR)在临床工作中屡见不鲜,对孕妇心理及胎儿预后有一定的影响,我国发病率平均为6.39%[1-4]。胎儿生长受限时围生儿的患病率和死亡率均高于正常体重胎儿,对远期体格和智力发育也有一定影响[5]。近年来随产前检查的系统化和正规化,早期胎儿宫内生长受限的诊断率逐渐升高,早期发现、早期诊断、早期干预具有重要意义。

Impact of race‐based customization on detection of fetal growth restriction
Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 4, Page 480-485, October 2025.ABSTRACT Objective Fetal growth standards determine which fetuses are diagnosed with fetal growth restriction (FGR) and become candidates for enhanced fetal monitoring. Given the existence of race‐based differences in fetal and neonatal weights, we sought to determine the impact of race‐based customization of fetal growth curves on the antenatal ...

母血甲胎蛋白联合彩色多普勒超声在孕10-22周胎儿神经管畸形筛查的应用研究
Zhongguo shiyan zhenduanxue, 2016 我国每年出生的畸形儿童约占每年出生人口总数的1%-4%[1,2],其中胎儿神经管畸形（neural tube defects,NTD）在中枢神经系统缺陷畸形胎儿中的发生率最高,包括无脑儿、脊柱裂、脑膜膨出等,占先天性畸形中的第2位[3,4],随着环境污染的日益加剧,发病率呈明显升高趋势,是死胎、死产及新生儿死亡的主要原因,存活的胎儿也多存在严重的功能障碍,无法正常生活 ...
