COMPARISON BETWEEN DOPPLER AND NON-STRESS TEST IN PREGNANT WOMEN WITH OLIGOHYDRAMNIOS FOR ASSESSMENT OF PERINATAL OUTCOME AT POST-DATE PREGNANCY

High-risk pregnancies, especially with oligohydramnios, significantly increase infant mortality and morbidity. Obstetrics focuses on preventing complications, with Doppler and Non-Stress Test (NST) being key in assessing fetal health. Oligohydramnios, varying in incidence and severity, can lead to diverse perinatal outcomes, including increased cesarean sections rate and fetal pulmonary complications. The study aims to compare the value of fetal doppler ultrasound and fetal non-stress test in prediction of perinatal outcome in oligohydramnios at post-date pregnancy. This cohort study was conducted at Al-Elwiya Maternity Teaching Hospital from 1st January to 1st December 2023, including 100 post-date pregnant women with oligohydramnios. Exclusions include active labor, contraindications to vaginal delivery, and refusal to participate. Data collection covered demographics, medical history, surgical history, physical exams, Doppler ultrasound findings, and non-stress tests. Outcomes for both mother and neonate, including delivery type, complications, and neonatal health, were recorded, ensuring ethical considerations and confidentiality. This study classified post-date pregnant women with oligohydramnios into four groups based on NST and Doppler results. Group 1 (reactive NST, normal Doppler) comprised 32%, Group 2 (normal NST, abnormal Doppler) 26%, Group 3 (abnormal NST, normal Doppler) 30%, and Group 4 (both abnormal) 12%. It found significant differences in delivery modes, with more cesarean sections in Groups 2 and 4. Neonatal Intensive Care Unit (NICU) admissions and Intrauterine Growth Restriction (IUGR) incidence varied notably across groups, highlighting the importance of these tests in predicting adverse perinatal outcomes. NST and Doppler effectively assess perinatal outcomes in oligohydramnios, guiding delivery methods and NICU admissions, and highlighting variable risks.

高危妊娠，尤其是合并羊水过少（oligohydramnios）者，可显著升高婴儿死亡率与发病率。妇产科学以并发症防控为核心目标，多普勒超声与非应激试验（Non-Stress Test, NST）是评估胎儿健康状态的关键手段。羊水过少的发病率与严重程度存在异质性，可引发多种围产期不良结局，包括剖宫产率上升及胎儿肺部并发症。本研究旨在对比胎儿多普勒超声与非应激试验在过期妊娠合并羊水过少患者围产期结局预测中的应用价值。本队列研究于2023年1月1日至12月1日在Al-Elwiya妇产教学医院开展，共纳入100例过期妊娠合并羊水过少的孕妇。排除标准包括临产状态、阴道分娩禁忌证及拒绝参与研究者。研究收集的资料涵盖人口统计学特征、既往病史、手术史、体格检查结果、多普勒超声检查结果及非应激试验结果。研究记录了产妇与新生儿的各项结局指标，包括分娩方式、并发症发生情况及新生儿健康状态，并严格遵循伦理审查与保密要求。本研究根据非应激试验与多普勒超声检查结果，将过期妊娠合并羊水过少的孕妇分为四组：第1组（非应激试验反应型、多普勒超声结果正常）占比32%，第2组（非应激试验正常、多普勒超声结果异常）占比26%，第3组（非应激试验异常、多普勒超声结果正常）占比30%，第4组（两项检查均异常）占比12%。研究发现各组分娩方式存在显著差异，第2组与第4组的剖宫产率更高。各组新生儿重症监护病房（Neonatal Intensive Care Unit, NICU）收治率与宫内生长受限（Intrauterine Growth Restriction, IUGR）发生率存在显著差异，凸显了上述两项检查在预测不良围产期结局中的重要价值。非应激试验与多普勒超声可有效评估羊水过少患者的围产期结局，为分娩方式选择及新生儿重症监护病房收治决策提供依据，并可区分不同层级的妊娠风险。
