The role of cord blood viscosity in determining the umbilical artery Doppler flow velocity waveform (FVW) was investigated in 22 normal pregnancies and 29 complicated pregnancies. FVWs were quantified by calculating the pulsatility index (PI). There was a significant correlation between an abnormal PI (more than 2 SD from the mean) and fetal growth retardation (less than 5th birthweight centile), cesarean section for fetal distress, and raised cord blood hematocrit. However, there was no relationship between whole blood or plasma viscosity measurements and the umbilical artery PI.
在22例正常妊娠和29例复杂妊娠中，研究了脐血粘度在确定脐动脉多普勒血流速度波形（FVW）中的作用。通过计算搏动指数（PI）对FVW进行量化。异常PI（超过均值2个标准差）与胎儿生长受限（低于出生体重第5百分位数）、因胎儿窘迫行剖宫产以及脐血血细胞比容升高之间存在显著相关性。然而，全血或血浆粘度测量值与脐动脉PI之间没有关系。
