[Perinatal fetal prognosis of essential hypertension complicating pregnancy].
Pregnancy induced hypertension (PIH) in patient of essential hypertension is a high risk factor for both mother and child. From July 1959 to June 1991 there were 52,898 deliveries after the 28th week of gestation in our hospital, among whom essential hypertension occurred in 2.5% and 337 cases were superimposed by PIH with an incidence of 25.9%. There was a perinatal fetal mortality rate of 117.6/1000 in those 337 cases. A scoring system for perinatal fetal prognosis was worked out. The clinical criteria consist of: preexisting diastolic blood pressure, the highest diastolic pressure during pregnancy, proteinuria and the time of onset of PIH. A perinatal survival rate of 75.0% was obtained in those patients with preexisting diastolic pressure lower than 14.8 kPa (110 mmHg). A perinatal survival rate of more than 98.0% may be expected of those patients developing P I H after the 36th week of gestation. When the score is more than 8, the patient could usually get a living baby. If the score is less than 7, it is important to treat P I H effectively, terminate pregnancy at an appropriate time and keep the baby in the intensive care unit.
