Objective:To studyMgSO4 effecton fetal
MCA and UA blood flow changesusing
Doppler ultrasoundin cases of severe PET and eclampsia. Materials and Methods: A
total of 40 patients with severe PET admitted to El-Shatby Maternity University
Hospital, Alexandria (Egypt) were examined before and after administration of
MgSO4 using Doppler study to measure fetal MCAand UA
blood flow changes. Results: After administrationof MgSO4,
the meanRI of UA, PI of UA showed a statistically significant decrease (P <
0.001) also the systolic-diastolic ratio (p = 0.001). Mean resistivity index (RI)
cerebral showed a statistically significant increasing (P = 0.001),
