To develop a research database for mother-and-child clinical and laboratory data and digital foetal heart rate (FHR) recordings.
The Base Bien Naître (BBN) database was derived from a single-centre health data warehouse. It contains exhaustive data on all parturients with a singleton pregnancy, a vaginal or caesarean delivery in labour with a cephalic presentation after at least 37 weeks of amenorrhea, and a live birth between February 1st, 2011, and December 31st, 2018. On arrival in the delivery room, the FHR was recorded digitally for at least 30 min. A cord blood sample was always taken in order to obtain arterial pH (pHa). More than 6,000 recordings were analyzed visually for the risk of foetal acidosis and classified into five groups (according to the French College of Gynaecologists and Obstetricians (CNGOF) classification) or three groups (according to the International Federation of Gynaecology and Obstetrics (FIGO) classification).
Of the 16,089 files in the health data warehouse, 11,026 were complete and met the BBN's inclusion criteria. The FHR digital recordings were of good quality, with low signal loss (median [interquartile range]: 7.0% [4.3;10.9]) and a median recording time of 304 min [190;438]). In 3.7% of the children, the pHa was below 7.10. We selected a subset of 6115 records with good-quality FHR recordings over 120 min and reliable cord blood gas data: 692 (11.3%) had at least a significant risk of acidosis (according to the CNGOF classification), and 1638 (26.8%) were at least suspicious (according to the FIGO classification).
The BBN database has been designed as a searchable tool with data reuse. It currently contains over 11,000 records with comprehensive data.
开发一个用于母婴临床和实验室数据以及数字化胎儿心率 (FHR) 记录的研究数据库。
Base Bien Naître (BBN) 数据库源自一个单一中心的健康数据仓库。它包含了所有单胎妊娠、阴道或剖宫产分娩、头位、至少 37 周以上闭经、活产的产妇的详尽数据，时间范围为 2011 年 2 月 1 日至 2018 年 12 月 31 日。产妇进入产房后，FHR 至少记录 30 分钟。为了获得动脉 pH 值 (pHa)，总是会采集脐带血样本。对超过 6000 次的 FHR 记录进行了视觉分析，以评估胎儿酸中毒的风险，并将其分为五个组（根据法国妇产科医师学院 (CNGOF) 分类）或三个组（根据国际妇产科联合会 (FIGO) 分类）。
在健康数据仓库的 16089 个文件中，有 11026 个文件是完整的，符合 BBN 的纳入标准。FHR 数字记录质量良好，信号丢失率低（中位数 [四分位间距]：7.0% [4.3;10.9]），中位数记录时间为 304 分钟 [190;438]）。在 3.7%的儿童中，pHa 低于 7.10。我们选择了一组 6115 次具有良好 FHR 记录和可靠脐带血气数据的记录子集：692 次（11.3%）至少存在酸中毒的显著风险（根据 CNGOF 分类），1638 次（26.8%）至少存在可疑情况（根据 FIGO 分类）。
BBN 数据库被设计为一个具有数据可搜索功能的工具，可以重复使用数据。目前，它包含了超过 11000 次的记录，具有全面的数据。
