To assess feasibility and physiological variation of fetal ductus venosus Doppler velocimetry during the first stage of labor between uterine contractions.
A prospective cross-sectional study including 23 healthy women with low-risk pregnancies. Maximum velocities during ventricular systole (S) and atrial contraction (A) were recorded in the ductus venosus between contractions. Pulsatility index for veins (DV PIV) and the ductus venosus index (DVI) were also calculated.

Acceptable ductus venosus waveforms were acquired in 19 fetuses (83%). The mean +/- SD values of the ductus venosus index and the pulsatility index were 0.46 +/- 0.07 (95% CI: 0.42-0.49) and 0.57 +/- 0.12 (95% CI: 0.51-0.63), respectively. The mean +/- SD values of maximum velocities during ventricular systole (S) and atrial contraction (A) were 65 +/- 8 cm/s and 35 +/- 5 cm/s, respectively.
Ductus venosus blood flow velocities can be assessed during labor. This calls for an extension of the detection possibilities of intrauterine fetal status and gives an idea to establish reference ranges for these circulation parameters during labor in the future.
评估宫缩间歇期第一产程胎儿静脉导管多普勒测速的可行性及生理变化。
一项前瞻性横断面研究，纳入23例低风险妊娠的健康女性。记录宫缩间歇期静脉导管心室收缩期（S）和心房收缩期（A）的最大流速。还计算了静脉搏动指数（DV PIV）和静脉导管指数（DVI）。

19例胎儿（83%）获得了可接受的静脉导管波形。静脉导管指数和搏动指数的平均值±标准差分别为0.46±0.07（95%可信区间：0.42 - 0.49）和0.57±0.12（95%可信区间：0.51 - 0.63）。心室收缩期（S）和心房收缩期（A）最大流速的平均值±标准差分别为65±8 cm/s和35±5 cm/s。
产程中可评估静脉导管血流速度。这需要扩展宫内胎儿状况的检测可能性，并为将来建立产程中这些循环参数的参考范围提供思路。
