在12例需要肺动脉导管插入术的患者中，使用多普勒和热稀释技术测量心输出量。多普勒技术准确预测了热稀释法的测量值（r = 0.91; P < .001）。18例正常妊娠晚期患者和36例未接受硫酸镁以外药物治疗的先兆子痫患者仅用多普勒进行评估。值得注意的是先兆子痫之间的异质性。虽然他们的平均全身血管阻力升高，但其范围为2256-648达因·秒·厘米-5。心输出量范围为13.2-3.9 L/min。
In 12 patients requiring pulmonary artery catheterization, cardiac output was measured using Doppler and thermodilution techniques. The Doppler technique accurately predicted measurements made by thermodilution (r = 0.91; P < .001). Eighteen normal patients in the third trimester and 36 preeclamptics who had not been treated with medications other than magnesium sulfate were evaluated with Doppler alone. Of note was the heterogeneity among preeclamptics. Although their mean systemic vascular resistance was elevated, it ranged from 2256–648 dyne·sec·cm-5. Cardiac output ranged from 13.2–3.9 L/minute.
