羊水过少胎儿电子监护仪图像的探讨

Exploration on Monitoring Pattern of Fetal Heart Rate with Oligohydramnios

本文通过对86例羊水过少胎儿电子监护仪图像分析,发现羊水过少的胎儿电子监护仪的图像有如下特点:1.胎心基线变异静止型明显增多(P<0.01)。2.胎动及胎动时胎心率增速反应为无反应型明显增多(P<0.01)。3.异常的胎监图像以延长减速(简称PD)多见。4.胎心率基线异常增多(心动过速或心动过缓)。结合分娩所见及围产儿预后,认为胎心率基线变异静止型和胎动及胎动时胎心率增速反应为无反应型是羊水过少者胎儿宫内缺氧早期信号;PD是胎儿宫内危险的征象,应不失时机地给予积极处理。

This article analysed the monitoring patterns of Fetal Heart Rate (FHR) in 86 patients with oligohydramnios. We found the following characteristics. The static type and mutation type and tachycardia or bradycardia in base line of FHR,No reaction type in non —stresstest (NST) and the prolonged deceleration (PD) of FHR are all in majority. @Thus,we consider the static type in base line of FHR and no reaction type in NST to be the early signals in oligohydramnios complicated fetal distress, PD may signify fetal distress which reouires Prompt attention.
