Hypertensive disorders in pregnancy: analysis of 110 cases.
One hundred and ten cases of hypertensive disorders in pregnancy were analyzed retrospectively. There were 16 cases of gestational hypertension, 36 cases of mild preeclampsia, 43 cases of severe preeclampsia, 6 cases of eclampsia, and 9 cases of chronic hypertension with superimposed severe preeclampsia. The principle of management was conservative in order to prolong pregnancy for patients remote from term. Corticosteroids were used to accelerate fetal lung maturity for patients with gestations of less than 36 weeks and magnesium sulfate was administered to prevent seizures. Fetal heart rate monitoring was done routinely and doppler blood flow velocity time wave form study of uterine and umbilical arteries was also performed in the latter part of the study. The cesarean section rate in gestational hypertension and mild preeclampsia was comparable to the general obstetric population in our institute (26.9% vs. 21.2%), but the rate of severe forms of the disease including severe preeclampsia, eclampsia, and chronic hypertension with superimposed severe preeclampsia was as high as 77.6%. Fetal distress was the main indication of section. There were 2 cases (6.9%) of mild respiratory distress syndrome, and all recovered uneventfully. The patients with severe forms of the disease had a higher incidence of small infants for gestational age (72%) and delivery at less than 36 weeks' gestation (48.2%). The corrected perinatal mortality rate was 5.4%. No maternal death was encountered. It was concluded that pregnancy could be prolonged in the interest of fetal lung maturity under meticulous maternal-fetal monitoring without endangering the mother.
