METHODS: Over a 3-year period a group of pregnant women with cardiac disease was followed until 6 weeks postpartum. Twenty women with pulmonary hypertension were compared with 20 controls without pulmonary hypertension with particular reference to maternal and fetal outcome. Analysis of data was carried out using Fisher's exact test and Student's t-test.

RESULTS: Except for Eisenmenger's syndrome, there were no differences in maternal morbidity and mortality between the two groups. There were more low birth weight babies but no significant differences in premature delivery rate, mode of delivery or perinatal mortality.

METHODS: Subjects were 200 consecutive patients admitted to Kuala Tereng-ganu General Hospital, Malaysia with severe hypertension in pregnancy between August 1989 and June 1990. Admission criteria were an ongoing viable pregnancy more than 28 weeks and diastolic blood pressure (DBP) more than 120 mmHg. The patients were randomly divided into 2 groups. In group I, sublingual nifedipine 5 mg was administered and repeated after 15 minutes if DBP > 120 mmHg; and in group II hydrallazine 5 mg was intravenously injected and repeated after 15 minutes if DBP > 120 mmHg. Both groups were put on hydrallazine infusion if DBP > 120 mmHg after 30 minutes. The Chi-square test was used for analysis with significance at p < 0.05.

RESULTS: There was no statistical difference in the efficacy of therapy for decreasing blood pressure between the 2 groups. The groups were comparable by age, parity, gestational age at presentation, birth weight of infants, incidence of postpartum haemorrhage and fetal distress. Caesarian section rates were similar. In the observational studies on nurses administering the drugs, no significant difficulties were observed.
