Nonreassuring fetal heart rate patterns (NRFHRP) suggest fetal conciliation or a deteriorating ability to handle the stress of labor. Nearly half of stillbirths occurring worldwide are due to hypoxia which is primarily manifested by NRFHRP. Hence, this study assessed the proportion and associated factors of NRFHRP in the Finote Selam primary hospital, North West Ethiopia.
An institution-based retrospective cross-sectional study was conducted from March 1 to April 1, 2019, on 364 charts of mothers who gave birth from January 2017 to January 2018 at the Finote Selam primary hospital. A computer-based simple random sampling technique was used to select charts. A secondary data was collected using a structured questionnaire adapted from different literatures. The data was entered and analyzed using Epi Info version 7 and Statistical Package for the Social Sciences (SPSS) version 23.0. Binary logistic regression was executed, and all explanatory variables with value < 0.2 were entered into multivariable logistic regressions. Multivariable logistic regression was used to control the effect of confounding variables and to identify factors affecting NRFHRP. Odds ratios with 95% confidence intervals were computed, and statistical significance was declared if < 0.05.
Out of 364 total deliveries, NRFHRP was detected on 55 (15.1%) fetuses, and the commonest NRFHRP detected was bradycardia 44 (80%). Most NRFHRP (38.18%) occurred on the deceleration phase of labor. There was no identified possible cause for NRFHRP on 34.5% of cases. Referral from nearby health institutions [AOR = 2.832 (95% CI 1.457, 5.503)], primigravida [AOR = 2.722 (95% CI 1.377, 5.381)], augmentation of labor [AOR = 3.664 (95% CI 1.782, 7.534)], and meconium-stained amniotic fluid [AOR = 6.491 (95% CI 3.198, 13.173)] were significantly associated with NRFHRP.
The proportion of NRFHRP is high. Referral from nearby health institutions, primigravida mothers, augmentation of labor, and meconium-stained amniotic fluid were significantly associated with NRFHRP. Implementing a better referral link and close monitoring during follow-up could minimize NHFHRP.
非胎儿心率监护仪（NRFHRP）模式表明胎儿处于镇静状态或处理分娩压力的能力正在恶化。全球近一半的死产是由于缺氧引起的，而缺氧主要表现为 NRFHRP。因此，本研究评估了在埃塞俄比亚西北部的 Finote Selam 初级医院，NRFHRP 的比例及其相关因素。
这是一项 2019 年 3 月 1 日至 4 月 1 日在 Finote Selam 初级医院进行的基于机构的回顾性横断面研究，研究对象为 2017 年 1 月至 2018 年 1 月期间分娩的 364 名母亲的病历。采用计算机基简单随机抽样技术选择病历。使用改编自不同文献的结构化问卷收集二次数据。数据通过 Epi Info 版本 7 和社会科学统计软件包（SPSS）版本 23.0 进行录入和分析。执行二元逻辑回归，所有 值 < 0.2 的解释变量均纳入多变量逻辑回归。多变量逻辑回归用于控制混杂变量的影响，并确定影响 NRFHRP 的因素。计算比值比（OR）及其 95%置信区间（CI），如果 < 0.05，则表示有统计学意义。
在 364 例总分娩中，55 例（15.1%）胎儿检测到 NRFHRP，最常见的 NRFHRP 是心动过缓 44 例（80%）。大多数 NRFHRP（38.18%）发生在分娩减速阶段。34.5%的病例无法确定 NRFHRP 的可能原因。附近医疗机构的转介 [比值比（OR）= 2.832（95%置信区间（CI）1.457，5.503）]、初产妇 [OR = 2.722（95% CI 1.377, 5.381）]、引产 [OR = 3.664（95% CI 1.782, 7.534）]和胎粪污染羊水 [OR = 6.491（95% CI 3.198, 13.173）]与 NRFHRP 显著相关。
NRFHRP 的比例很高。附近医疗机构的转介、初产妇、引产和胎粪污染羊水与 NRFHRP 显著相关。实施更好的转诊联系和密切监测随访可以最大限度地减少 NHFHRP。
