Several studies have previously assessed the value of changes in the fetal adrenal gland to predict preterm labor. The aim of this study is to evaluate the correlation between fetal adrenal gland measurements after 36 weeks and obstetrical outcomes.
Abdominal two-dimensional (2D) ultrasound is used to measure in the transversal plane the length of fetal zone (D1), the width (D2), and the length (D3) of fetal adrenal gland, and, subsequently, the fetal zone enlargement (FZE), in 98 primigravida women after 36 weeks. Labor and delivery outcomes were assessed and compared with these measurements.
FZE changes had no association with spontaneous onset of labor. No association was found between all adrenal gland measurements and delivery onset. There was a significant relationship between D1, D2, and D3 and the delivery method. Patients delivered by cesarean section had smaller fetal adrenal gland dimensions, defining D1= 0.16 cm, D2 = 0.7 cm, and D3 = 2.37 cm as cutoff levels based on receiver operator characteristics curves.
The 2D measurement of the fetal adrenal gland after 36 weeks seems to predict the delivery method in low-risk primigravida women.

先前已有几项研究评估了胎儿肾上腺变化预测早产的价值。本研究旨在评估 36 周后胎儿肾上腺测量值与产科结局之间的相关性。
98 例初产妇在 36 周后使用腹部二维（2D）超声在横切面测量胎儿带区（D1）的长度、宽度（D2）和长度（D3），随后测量胎儿带区增大（FZE）。评估并比较了这些测量值与分娩和分娩结局的关系。
FZE 变化与自发性临产无关。所有肾上腺测量值与分娩开始均无关联。D1、D2 和 D3 与分娩方式有显著关系。行剖宫产分娩的患者胎儿肾上腺尺寸较小，基于受试者工作特征曲线，将 D1=0.16cm、D2=0.7cm 和 D3=2.37cm 定义为截断值。
36 周后胎儿肾上腺的 2D 测量似乎可预测低危初产妇的分娩方式。
· 我们评估了 36 周后胎儿肾上腺的测量值与产科结局的关系。
· 所有肾上腺测量值与分娩开始均无关联。
· 行剖宫产分娩的患者胎儿肾上腺尺寸较小。
