Abstract | AIMS: MATERIAL AND METHODS: Forty-eight women with gestational age greater than 34 weeks with mild preeclampsia or gestational hypertension were randomly assigned to receive either magnesium sulfate or placebo. Pre- and post- magnesium sulfate pulsatility index of umbilical and fetal middle cerebral artery were compared by Mann-Whitney U-test between the groups. Within-group comparison was conducted using Wilcoxon's signed rank test. RESULTS: There was a significant reduction in the post- magnesium sulfate umbilical artery pulsatility index in the intervention group (median 0.88 [0.82-1.03]) when compared to the placebo group (median 1.00 [0.89-1.10]). Post- magnesium sulfate fetal middle cerebral artery pulsatility index in the intervention group (median 1.78 [1.63-1.98]) did not show a significant change compared to the placebo group (median 1.65 [1.42-1.91]). Within-group comparison showed change in both variables after treatment in the intervention group. CONCLUSION:
Magnesium sulfate produces a significant decrease in fetal umbilical artery and middle cerebral artery pulsatility index.
