Forty-two women with pregnancies complicated by pre-eclampsia and heavy proteinuria greater than or equal to 5 g/24 h were referred for conservative management to the high-risk obstetric unit in the John Radcliffe Hospital, Oxford, over a period of 5 years. Hyperuricaemia preceded the onset of heavy proteinuria in all 42 women. Most of the women had severe hypertension, but none developed eclampsia and there were no major maternal complications. Delivery was necessary within 2 weeks of onset of severe proteinuria in 88.1% of cases, although in some very preterm pregnancies delivery could be deferred for 3 or more weeks. Thirty-five women (83%) were delivered by caesarean section, 91% of whom were delivered urgently before the onset of labour. The high rate of urgent preterm operative delivery underlines the uncertainty of advanced pre-eclampsia and the need for close monitoring if delivery is to be deferred. Perinatal mortality was high; all the perinatal deaths occurred in babies of less than 29 weeks gestation. Despite heavy proteinuria, postpartum recovery was good. Three months after delivery, all but one patient had no significant proteinuria. There was no evidence of residual renal dysfunction. Although the outlook for pre-eclampsia with heavy proteinuria is limited, in a few cases pregnancy can be prolonged for significant periods of time without apparently prejudicing maternal safety and permitting enhancement of maturity at birth. The observations justify cautious conservative management even when heavy proteinuria is present.
