Effect of self-made traditional Chinese medicine decoction on pregnancy outcome in patients with hypertensive disorder complicating pregnancy / 中国中西医结合急救杂志

ABSTRACT

Objective To investigate the effect of self-made traditional Chinese medicine(TCM) decoction on pregnancy outcome in patients with hypertensive disorder complicating pregnancy. Methods A total of 124 pregnant hypertensive patients admitted to the Department of Critical Care of Guizhou Provincial People's Hospital from October 2016 to October 2018 were enrolled. The 62 patients who were treated with western medicine conventional method;62 patients who were treated with self-made TCM decoction on the basis of western medicine conventional method. The western medicine conventional treatment group was given magnesium sulfate combined with nicardipine; the self-made TCM treatment group was supplemented with TCM decoction on the basis of conventional western medicine treatment (composition uncaria, raw oyster 20 g, gastrodia elata, eucommia, salvia miltiorrhiza, medlar rehmannia glutinosa each 15 g, rhizoma, mulberry parasitic, astragalus, ophiopogonis each 10 g. Severe headache and dizziness plus tortoise shell, gentian grass 15 g, anemarrhenae 10 g; severe edema plus cassia twig, aristolochiae 15 g, astragali, ginger skin 10 g), be decocted in water for oral dose, morning and evening oral, one dose a day, 1 week for a course of treatment, the two groups were continued for 4 weeks after the evaluation of clinical efficacy. The changes of blood pressure and blood coagulation parameters, placental bed arterial hemodynamics, pregnancy outcome index were observed before and after treatment; antihypertensive effects and adverse reactions after treatment were recorded. Results After treatment, the systolic blood pressure (SBP), diastolic blood pressure (DBP), Fibrinogen (Fib), placental bed arterial pulsation index (PI), end-systolic blood flow velocity and end-diastolic blood flow velocity ratio (S/D) and resistance index (RI) in both groups were lower than those before treatment, the prothrombin time (PT) and activated partial thromboplastin time (APTT) were significantly longer than before treatment, and the time-averaged flow rate (TAV) increased than that before treatment; SBP, DBP, Fib, PI, S/D and RI were significantly lower in self-made TCM treatment group than those in western medicine conventional treatment group [SBP (mmHg, 1 mmHg = 0.133 kPa) 114.26±17.07 vs. 132.72±17.64, DBP (mmHg) 82.98±6.24 vs. 90.09±6.48, Fib (g/L) 3.21±0.45 vs. 3.64±0.31, PI 0.59±0.14 vs. 0.75±0.15, S/D 1.70±0.21 vs. 1.93±0.25, RI 0.43±0.08 vs. 0.54±0.12, all P < 0.05], PT, APTT, TAV in self-made TCM treatment group were significantly higher than western medicine conventional treatment group [PT (s) 12.26±0.57 vs. 11.72±0.44, APTT (s) 27.11±1.34 vs. 25.69±1.48, TAV (cm/s) 15.64±2.88 vs. 12.49±2.76, all P < 0.05]. The rate of cesarean section, postpartum hemorrhage, fetal heart abnormality and neonatal asphyxia in self-made TCM treatment group were significantly lower than those in western medicine conventional treatment group [cesarean section rate 9.84% (6/61) vs. 27.78% (15/54), postpartum hemorrhage rate 1.64% (1/61) to 14.81% (8/54), fetal heart abnormal rate 3.28% (2/61) vs. 16.67% (9/54), the incidence of neonatal asphyxia 1.64% (1/61) vs. 12.96% (7/54), all P < 0.05]. The total effective rate of the self-made TCM treatment group was significantly higher than that of western medicine conventional treatment group [98.39% (61/62) vs. 87.10% (54/62), P < 0.05]. However, there was no significant difference in the incidence of adverse reactions between the self-made TCM treatment group and western medicine conventional treatment group [16.39% (10/61) vs. 16.67% (9/54), P > 0.05]. Conclusion Self-made TCM decoction can improve the maternal and infant outcomes by improving the hypercoagulable state and placental hemodynamics in hypertensive patients with hyperthyroidism, the antihypertensive effect is remarkable and the safety is good.
