Abstract

Aim

This study aimed to evaluate the role of intra-abdominal umbilical vein (FIUV) diameter in predicting fetal distress and the need for emergency cesarean section during labor in fetuses with small-for-gestational-age (SGA) or late-onset fetal growth restriction (late-onset FGR).

Methods

A prospective study was conducted between March 2021 and January 2022, involving 51 pregnant women with SGA or late-onset FGR delivering at or beyond 37 weeks' gestation. FIUV diameter was measured via transabdominal ultrasonography, and labor outcomes were assessed. Fetuses were monitored continuously, with cesarean delivery performed for category 3 fetal heart rate tracings. Statistical analyses compared FIUV diameter and FIUV/head circumference (HC) ratios between fetuses with and without distress.

Results

Of the 51 participants, 8 (15.7%) required cesarean delivery due to fetal distress. FIUV diameter was significantly smaller in the distress group (5.20 vs. 8.68 mm; p = 0.006), as well as the FIUV/HC ratio (1.60 vs. 2.65; p = 0.004). Receiver operating characteristic analysis showed AUC values of 0.803 for FIUV and 0.814 for FIUV/HC, with sensitivities of 56.8% and specificities of 100% at cutoff values of 6.2 mm and 1.95, respectively. One-minute Apgar scores were lower in the distress group (6.88 vs. 8.23; p = 0.01).

Conclusions

FIUV diameter is a potential predictor of fetal distress in SGA and late-onset FGR fetuses. Larger FIUV diameters may indicate better fetal adaptation, which in turn reduces labor-related complications. These findings suggest a role for FIUV assessment in guiding delivery planning to improve maternal and neonatal outcomes.

预测生长受限胎儿的胎儿窘迫：脐静脉直径的作用。

目的：本研究旨在评估腹内脐静脉（FIUV）直径在预测小胎龄（SGA）或迟发性胎儿生长受限（late-onset fetal growth restriction， FGR）胎儿窘迫和产程中是否需要紧急剖宫产中的作用。方法：在2021年3月至2022年1月期间进行了一项前瞻性研究，涉及51名妊娠37周或以上分娩的SGA或晚发性FGR孕妇。通过经腹超声测量FIUV直径，并评估分娩结果。连续监测胎儿，剖宫产进行3类胎儿心率追踪。统计分析比较了有和无窘迫胎儿的FIUV直径和FIUV/头围（HC）比率。结果：51名参与者中，8名（15.7%）因胎儿窘迫需要剖宫产。窘迫组FIUV直径显著小于（5.20比8.68 mm, p = 0.006）， FIUV/HC比值显著小于（1.60比2.65,p = 0.004）。受试者工作特征分析显示，FIUV的AUC值为0.803，FIUV/HC的AUC值为0.814，在截止值为6.2 mm和1.95时，灵敏度为56.8%，特异性为100%。焦虑组1分钟Apgar评分较低（6.88比8.23;p = 0.01）。结论：FIUV直径是SGA和晚发性FGR胎儿胎儿窘迫的潜在预测因子。更大的FIUV直径可能表明更好的胎儿适应，从而减少分娩相关并发症。这些发现表明FIUV评估在指导分娩计划以改善孕产妇和新生儿结局方面的作用。
