The purpose of modern obstetrics is to obtain tracers of the fetal cerebral risk during labor, enabling to deliver the child before cerebral ischemia occurs. Recording of the fetal heart and measurement of acid-base balance are remarkable tracers; however, a much better precision is desired to avoid unnecessary or too late caesarean sections. Blood velocity measurement by Döppler at the level of the vessels at the base of the fetal skull is technically possible during labor; this has been demonstrated in 8 fetuses. The major cerebral index D/S during labor is 0.40 +/- 0.04, i.e. slightly lower than the mean index measured at the cord (0.50 +/- 0.07). In case of decelerations, it decreases to a mean value of 0.22 +/- 0.02. These preliminary results permit to hope that long-term measurements with continuous Döppler, of the arterial fetal cerebral flow, provide a direct and accurate tracer of the risk of cerebral ischemia during labor.
现代产科学的目的是在分娩期间获取胎儿脑部风险的追踪指标，以便在脑缺血发生前娩出胎儿。胎儿心率记录和酸碱平衡测量是显著的追踪指标；然而，为避免不必要的或过晚的剖宫产，需要更高的精确度。分娩期间通过多普勒测量胎儿颅骨底部血管水平的血流速度在技术上是可行的；这已在8例胎儿中得到证实。分娩期间主要脑指数D/S为0.40±0.04，即略低于在脐带处测得的平均指数（0.50±0.07）。在出现减速的情况下，该指数降至平均值0.22±0.02。这些初步结果让人希望，通过连续多普勒对胎儿脑动脉血流进行长期测量，能提供分娩期间脑缺血风险的直接且准确的追踪指标。
