Introduction. 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. Methods. 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 . Result. 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 [ (95% CI 1.457, 5.503)], primigravida [ (95% CI 1.377, 5.381)], augmentation of labor [ (95% CI 1.782, 7.534)], and meconium-stained amniotic fluid [ (95% CI 3.198, 13.173)] were significantly associated with NRFHRP. Conclusion. 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.

埃塞俄比亚西北部菲诺特塞拉姆初级医院中令人不安的胎儿心率模式的比例和相关因素

简介。令人不安的胎儿心率模式 (NRFHRP) 表明胎儿的安抚或处理分娩压力的能力正在下降。全世界近一半的死产是由于缺氧造成的，缺氧主要表现为 NRFHRP。因此，本研究评估了埃塞俄比亚西北部菲诺特塞拉姆初级医院 NRFHRP 的比例和相关因素。方法. 2019 年 3 月 1 日至 4 月 1 日，对 2017 年 1 月至 2018 年 1 月在 Finote Selam 初级医院分娩的 364 名母亲进行了基于机构的回顾性横断面研究。使用基于计算机的简单随机抽样技术来选择图表。使用改编自不同文献的结构化问卷收集二次数据。使用 Epi Info 7 版和社会科学统计软件包 (SPSS) 23.0 版输入和分析数据。执行二元逻辑回归，所有解释变量与值 < 0.2 进入多变量逻辑回归。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。计算了具有 95% 置信区间的优势比，并声明了统计显着性，如果. 结果。在 364 次分娩中，55 名 (15.1%) 胎儿检测到 NRFHRP，检测到的最常见的 NRFHRP 是心动过缓 44 (80%)。大多数 NRFHRP (38.18%) 发生在分娩的减速阶段。34.5% 的病例未发现 NRFHRP 的可能原因。从附近的卫生机构转诊[(95% CI 1.457, 5.503)]，初产妇 [(95% CI 1.377, 5.381)]，增加劳动力[(95% CI 1.782, 7.534)]和羊水胎粪染色[(95% CI 3.198, 13.173)] 与 NRFHRP 显着相关。结论。NRFHRP的比例很高。来自附近卫生机构的转诊、初产妇、增加分娩和羊水胎粪染色与 NRFHRP 显着相关。在随访期间实施更好的转诊链接和密切监测可以最大限度地减少 NHFHRP。
