摘要/Abstract

摘要： 探究一种创新的、无创的、反射式光体积描记术为基础的设备对产妇分娩和分娩期间血流动力学的连续监测情况。选取81例足月低风险产妇参与本研究。给产妇佩戴新型反射式PPG设备,该设备每5 s自动采集心输出量(CO)、血压(BP)、每搏输出量(SV)、全身血管阻力(SVR)、心率(HR),并将所有数据上传到基于智能手机的应用程序和数据云。使用Power BI分析工具(Microsoft)对收集的数据进行大数据分析。比较胎膜破裂、硬膜外麻醉、胎儿分娩和胎盘排出前后的平均测量值。结果显示,硬膜外麻醉与CO轻微升高相关(P＜0.05),原因是HR和SV均无显著增加。在SVR反向下降时,血压保持稳定(P＜0.05)。胎儿分娩与CO峰值相关,之后CO迅速下降(P＜0.05)。平均血压在整个分娩过程中保持稳定,胎儿分娩时略有增加(P＜0.05),反映出CO增加和SVR降低(P＜0.05)。胎盘排出与CO的第二个峰值和SVR的降低相关。因此,一种新型反射式PPG设备可用于对产妇在分娩和分娩期间的血流动力学监测中。并利用这些数据确定正常值和异常值,以便在分娩和分娩期间制定安全方案。

Abstract: Explore an innovative, non-invasive, reflective photoplethysmography based device for continuous monitoring of maternal hemodynamics during and after delivery. 81 full-term low-risk postpartum women were selected to participate in this study. Wear a new reflective PPG device for postpartum women, which automatically collects cardiac output (CO), blood pressure (BP), stroke volume (SV), systemic vascular resistance (SVR), heart rate (HR) every 5 seconds, and uploads all data to smartphone based applications and data clouds. Use the Power BI analysis tool (Microsoft) to analyze the collected data. The mean measurements 41before and after rupture of membranes, epidural anesthesia, fetal delivery and placental excretion were compared. The results show that the epidural anesthesia was associated with a slight increase in CO (P＜0.05), because there was no significant increase in HR and SV. When SVR decreased inversely, the blood pressure remained stable (P＜0.05). Fetal delivery was associated with the peak value of CO, after which CO decreased rapidly (P＜0.05). The average blood pressure remained stable throughout the delivery process, and the fetus increased slightly during delivery (P＜0.05), reflecting an increase in CO and a decrease in SVR (P＜0.05). Placental excretion was associated with the second peak of CO and the reduction of SVR. Therefore, a new type of reflective PPG device can be used to monitor the hemodynamics of postpartum women during and during delivery. And use these data to determine normal and abnormal values, in order to develop safety plans during and during childbirth.
