Abstract
Nulliparous women [346] with pregnancy-induced hypertension prior to term were monitored in a high-risk pregnancy unit while awaiting fetal maturity. Management included ambulation as desired, regular hospital diet without salt restriction, blood pressure measured 4 times daily, weight and urine protein determined 3 times each week, creatinine clearance determined weekly and serial sonography to monitor fetal growth. Sedation and antihypertensive agents were not prescribed. Delivery was delayed until term unless hypertension persisted or recurred following an initial salutary response. Factors other than hypertension that contributed to the decision to effect delivery were rapid weight gain, decreasing creatinine clearance, appearance of significant proteinuria, suspected fetal growth retardation and the development of severe headache or scotomata. With this method of management the perinatal mortality rate was 9/1000. Only 5 infants developed the respiratory distress syndrome and all survived. There were 26 women who left the unit against medical advice. Severe hypertension subsequently developed in 7 of these women and 4 of their fetuses were stillborn. The perinatal mortality rate among this group of patients was 154/1000. The nulliparous patient with pregnancy-induced hypertension prior to term can be safely managed by hospitalization and close observation as a viable alternative to prompt delivery.
