[Hypertensive complications in pregnancy--a special evaluation of the Rhineland-Pfalz perinatal study].

In a special analysis of the perinatal database Rheinl.-Pfalz of the years 1989 and 1990 1,876 pregnancies with the risk-factor "gestosis" (2.4% of all deliveries) were evaluated. In comparison to all deliveries (n = 78,250) significantly different incident-rates could be observed: Sterility, working during pregnancy, nationality, parity, psycho-social stress, multiples, adipositas, diabetes mellitus, pathological increase of body weight, urinary infection, number and duration of antenatal hospitalisation. Prematurity and fetal retardation as well as placental insufficiency, pathological antenatal CTG, green amniotic fluid and intrapartel acidosis was seen much more often in the risk group, resulting in a much higher rate of caesarean section (50.1 versus 13.7%) and an increased maternal and fetal morbidity. Perinatal mortality was twice as high in the risk group compared to the control. Thought data quality is limited in this study covering a very larger area, the results underline the unchanged importance of hypertensive disorders in perinatology.
