Abstract：
OBJECTIVE:The purpose of this study was to investigate the effect of plasma volume expansion on the pulsatility indices of the fetal umbilical and middle cerebral arteries. STUDY DESIGN:Two hundred sixteen patients with severe preeclampsia, HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome, eclampsia, hypertension-related fetal growth restriction, and gestational ages between 24 and 34 completed weeks of gestation were assigned randomly for temporizing treatment with plasma volume expansion (n = 111 patients; 250 mL hydroxyethyl starch 6% twice daily in 4 hours, and NaCl 0.9% between doses of hydroxyethyl starch and with intravenous medication) or without plasma volume expansion (n = 105; only NaCl 0.9% when necessary with medication). Measurements of the pulsatility index of the umbilical and middle cerebral arteries were performed at admission, after 16 to 48 hours, 60 to 120 hours, and 7 to 11 days. RESULTS:Median gestational age was 30 weeks in both groups. Infused volumes of plasma volume expansion in the treatment group (total median, 813 mL/d) were associated with a significant decrease of hemoglobin concentration. Changes from baseline measurements of the umbilical and middle cerebral arteries were not different between the groups nor within subgroups during the first 7 to 11 days. CONCLUSION:Plasma volume expansion did not influence the pulsatility indices of the umbilical and middle cerebral arteries.
