    Notes: Objective To determine whether nifedipine or prazosin is the more appropriate second-line antihypertensive agent in pregnancy.Design Randomised controlled trial.Setting Tygerberg Hospital, a tertiary referral centre.Population Women with early, severe pre-eclampsia or hypertension in pregnancy, whose blood pressure could not be adequately controlled by methyldopa 2 g/day, but were otherwise stable.Methods Nifedipine or prazosin were given and increased as necessary in a stepwise fashion. Once the maximum dose was reached, the other drug was added in a crossover pattern. Failure to control blood pressure, or the onset of maternal/fetal complications were indications for delivery. Patients reaching a minimum gestation of 34 weeks without complications were delivered electively.Main outcome measures Antenatal days gained; major maternal complications and perinatal survival.Results Days gained on the second antihypertensive agent did not differ significantly (P= 0.9), while more days were gained using nifedipine as the crossover ‘third agent’ (P= 0.01). In the nifedipine group better renal function was recorded, but more cases with isolated low platelet counts occurred. More cases of pulmonary oedema as well as more nonviable mid-trimester and third trimester intrauterine deaths occurred in the prazosin group.Conclusion Nifedipine and prazosin as second agents allowed comparable amounts of time to be gained, although this changed when used as crossover third-line agents. The efficacy and safety of nifedipine in this study are consistent with the results of other studies. A greater number of intrauterine deaths occurred in the prazosin group.

    Notes: Objective To evaluate the safety and outcome of women undergoing expectant management of early onset, severe pre-eclampsia.Design Prospective case series extending over a five-year period.Setting Tygerberg Hospital, a tertiary referral centre.Population All women (n= 340) presenting with early onset, severe pre-eclampsia, where both the mother and the fetus were otherwise stable.Methods Frequent clinical and biochemical monitoring of maternal status, together with careful blood pressure control, in a high care obstetric ward.Main outcome measures Major maternal complications and prolongation of gestation.Results Multigravid women constituted 67% of the group. Antenatal biochemistry was reassuring with some expected, but not severe, deteriorations. Twenty-seven percent of women experienced a major complication, but few had poor outcomes. No maternal deaths occurred. Most major complications resolved quickly, necessitating only three admissions (0.8%) to the intensive care unit. One woman required dialysis. Pregnancies were prolonged by a mean (median) number of 11 days (9) before delivery, with more time being gained at earlier gestations. The postpartum inpatient stay (89%≤ 7 days, bearing in mind that 82% of women were delivered by caesarean section) was not extended.Conclusion Careful noninvasive management of early onset, severe pre-eclampsia in a tertiary centre can diminish and limit the impact of serious maternal complications. Valuable time to prolong the pregnancy and improve neonatal outcome is thereby gained.
