Abstract

OBJECTIVES

It was the aim of this study to examine intrapartum fetal heart rate (FHR) patterns in oligohydramnios.

METHODS

Subjects comprised 24 singleton pregnant women diagnosed with oligohydramnios and 470 controls. FHR patterns were analyzed at the end of the first stage and throughout the whole second stage of labor. Numbers of variable deceleration (VD), early deceleration (ED), late deceleration (LD) and prolonged deceleration (PD) per contraction were counted.

RESULTS

Frequencies of decelerations in oligohydramnios and controls were 5.4 +/- 14.5 and 2.0 +/- 6.6% for ED, 0.0 and 0.4 +/- 2.5% for LD, 17.6 +/- 20.6 and 12.2 +/- 13.3% for VD, and 1.8 +/- 3.7 and 0.8 +/- 3.0% for PD in the first stage of labor. In the second stage, frequencies were as follows: 5.1 +/- 10.5 and 1.5 +/- 6.1% for ED, 0.5 +/- 1.7 and 1.0 +/- 4.4% for LD, 30.1 +/- 22.0 and 43.9 +/- 29.3% for VD, and 29.3 +/- 33.2 and 12.6 +/- 22.5% for PD.

CONCLUSIONS

In cases of oligohydramnios, ED occurred frequently from the first stage of labor. In the second stage of labor, the frequency of PD was extremely high and the frequency of VD was low.

摘要

目的

本研究旨在探讨羊水过少时的产时胎儿心率（FHR）模式。

方法

研究对象包括24名单胎妊娠诊断为羊水过少的孕妇及470名对照组孕妇。在第一产程结束时及整个第二产程中分析FHR模式。计算每次宫缩时可变减速（VD）、早期减速（ED）、晚期减速（LD）及延长减速（PD）的次数。

结果

在第一产程中，羊水过少组和对照组的减速频率分别为：ED为5.4±14.%,5和2.0±6.6%；LD为0.0和0.4±2.5%；VD为17.6±20.6和12.2±13.3%；PD为1.8±3.7和0.8±3.0%。在第二产程中，减速频率如下：ED为5.1±10.5和1.5±6.1%；LD为0.5±1.7和1.0±4.4%；VD为30.1±22.0和43.9±29.3%；PD为29.3±33.2和12.6±22.5%。
