[Prediction and prevention of hypertension syndrome of pregnancy].

Analysis of mean artery pressure (MAP-2) according to the differentiation of symptom complex of TCM can predict the occurrence of hypertension syndrome of pregnancy (HSP) at patients' first visit to hospital during their middle gestational period (less than 24 pregnant weeks). 424 pregnant women (MAP-2 greater than or equal to 12kPa) were divided into 4 groups and given preventive treatment as follows: (1) The control group, 122 women, no drugs were given; (2) the Theragan group, 102 women; (3) the TCM (A) group, 100 women, those with Liver-Kidney deficiency of Yin or no apparent signs were given Qiju Dihuang Wan, and those with Spleen-Kidney deficiency of Yang were given Shenqiwan; (4) the TCM(B) group, 100 women, were given Salvia miltiorrhiza plus (A) group's drugs. The results of prediction: (1) The occurrence rate of HSP in the MAP-2 less than 12kPa group was 10. 5%; in the MAP-2 greater than or equal to 12kPa group, 49.2%. The difference was significant. (2) The rate of deficiency of Yin in the MAP-2 greater than or equal to 12kPa was significantly higher than in the MAP-2 less than 12kPa. The rate of HSP in the deficiency of Yin was higher than in the nondeficiency of Yin. The rate of HSP increased to 70. 7% in the MAP-2 greater than or equal to 12kPa with deficiency of Yin. The results of prevention: (1) The occurrence rates of HSP in 4 groups were 49.2%, 30.4%, 15% and 14% respectively. (2) There was no side effect for mother and infant after preventive treatment. No eclampsia occurred.
