摘要 目的:通过二维超声评估妊娠期糖尿病(GDM)胎儿的腹围(AC)、估计胎儿体重(EFW)和脂肪组织与大于孕龄儿(LGA)之间的关系,为临床评估和干预提供理论依据。方法:于妊娠28~30周经口服葡萄糖耐量试验(0G33")诊断为妊娠期糖耐量受损(GIGT)和GDM的单胎妊娠妇女,在妊娠晚期通过二维超声测量胎儿的Ac,EFW,肱骨皮下脂肪面积、股骨皮下脂肪面积,每4周1次,直至分娩前1周内。确定各指标预测GDMLGA的诊断价值并寻找恰当的截断值,计算相应的敏感性、特异性、误诊率和阳性预测值。结果:①对于GDM孕妇,在妊娠32周和36周用AC预测LGA较分娩前准确;②在分娩前用EFW预测LGA较妊娠32周和36周准确;③胎儿AC和EFW在妊娠32周、36周和分娩前对LGA的预测较胎儿脂肪组织准确;④在妊娠32周不能用胎儿肱骨皮下脂肪面积预测LGA,尽管分娩前一周的胎儿肱骨皮下脂肪面积预测价值优于孕36周,但总体预测价值中等;⑤在妊娠32周、36周和分娩前用胎儿股骨皮下脂肪面积预测LGA的预测价值中等,分娩前优于妊娠32周和36周。结论:①妊娠晚期常规测量GDM孕妇胎儿AC和EFW对预测LGA有临床实用价值,有助于加强对GDM患者的管理及分娩方式的选择,利于改善妊娠结局;②胎儿脂肪组织对GDMLGA的预测价值有限,尚不能作为较好的预测指标。
