Oligohydramnios is a predictor of fetal compromise and a useful tool in pregnancy management. It has been assessed using various techniques, including two-diameter pocket (2-DP) and amniotic fluid index (AFI).
To determine which of these two techniques best diagnose oligohydramnios and predicts adverse perinatal outcomes.
This was a comparative cross-sectional study conducted at Delta State University Teaching Hospital, Oghara in southern region of Nigeria over eight months period. One hundred high-risk pregnant women were recruited and ultrasound determination of amniotic fluid was performed using AFI and 2-DP. The women were followed up till delivery to determine adverse perinatal outcomes.
The indices of validity of AFI and the 2-DP were calculated and compared. The 2-DP had a higher sensitivity than AFI for adverse outcomes in high-risk pregnancies complicated by oligohydramnios.
The 2-DP technique should preferably be used for the assessment of oligohydramnios in high-risk pregnancies.
羊水过少是胎儿窘迫的预测指标，也是妊娠管理中有用的工具。它已经通过各种技术进行了评估，包括双径线（2-DP）和羊水指数（AFI）。
确定这两种技术中哪一种最能诊断羊水过少并预测不良围产结局。
这是一项在尼日利亚南部奥加拉地区的德尔塔州立大学教学医院进行的比较性横断面研究。在八个月的时间里，招募了 100 名高危孕妇，并使用 AFI 和 2-DP 进行超声羊水测定。这些妇女一直随访到分娩，以确定不良围产结局。
计算并比较了 AFI 和 2-DP 的有效性指标。对于由羊水过少引起的高危妊娠的不良结局，2-DP 的敏感性高于 AFI。
在高危妊娠中，应优选使用 2-DP 技术评估羊水过少。
