The introduction of the cardiotocogram (CTG) during labor has not been found to improve neonatal outcome. The search for a more reliable, less invasive, and patient-friendly technique is ongoing. The noninvasive fetal electrocardiogram (NI-fECG) has been proposed as one such alternative.
The aim of this study was to review the literature on the performance of NI-fECG for fetal monitoring during labor. Following the PRISMA guidelines, a systematic search in MEDLINE, EMBASE, and Cochrane Library was performed. Studies involving original research investigating the performance of NI-fECG during labor were included. Animal studies and articles in languages other than English, Dutch, or German were excluded. The QUADAS-2 checklist was used for quality assessment. A descriptive analysis of the results is provided.
Eight articles were included. Pooled analysis of the results of the separate studies was not possible due to heterogeneity. All studies demonstrate that it is possible to apply NI-fECG during labor. Compared with Doppler ultrasound, NI-fECG performs equal or better in most studies.
NI-fECG for fetal monitoring is a promising noninvasive and patient-friendly technique that provides accurate information. Future studies should focus on signal quality throughout labor, with the aim to further optimize technical development of NI-fECG.
在分娩过程中引入胎心监护图（CTG）并未发现能改善新生儿结局。因此，人们仍在寻找一种更可靠、侵入性更小且对患者更友好的技术。非侵入性胎儿心电图（NI-fECG）就是这样一种替代方法。
本研究旨在回顾关于在分娩过程中使用 NI-fECG 进行胎儿监测的文献。根据 PRISMA 指南，对 MEDLINE、EMBASE 和 Cochrane Library 进行了系统检索。纳入了研究 NI-fECG 在分娩过程中的性能的原始研究。排除了动物研究和非英语、荷兰语或德语的文章。使用 QUADAS-2 清单进行质量评估。提供了结果的描述性分析。
共纳入 8 篇文章。由于异质性，无法对单独研究的结果进行汇总分析。所有研究均表明，在分娩过程中应用 NI-fECG 是可行的。与多普勒超声相比，在大多数研究中，NI-fECG 的表现相等或更好。
NI-fECG 用于胎儿监测是一种有前途的非侵入性和对患者友好的技术，可提供准确的信息。未来的研究应侧重于整个分娩过程中的信号质量，旨在进一步优化 NI-fECG 的技术发展。
