To explore the effect of dydrogesterone tablets combined with Zishen Yutai pills on threatened abortion in early pregnancy and pregnancy outcomes.


This study retrospectively analyzed the clinical data of 100 patients with threatened abortion in early pregnancy who came to the Linhai Second People's Hospital/Taizhou Municipal Hospital from January 13, 2021, to January 13, 2022. According to different treatment methods, 48 patients treated with progesterone injection were assigned to the control group (CG), while 52 cases with the combined therapy of dydrogesterone tablets and Zishen Yutai pills were assigned to the observation group (OG). The two groups were compared in terms of the following parameters: treatment efficacy, whole blood high shear viscosity, hematocrit (HCT), plasma fibrinogen (FIB) level, spiral artery pulsatility index (PI), uterine spiral artery blood flow resistance index (RI), lumbar and abdominal pain relief time, hemostasis time, estrogen levels, pregnancy outcomes, neonatal adverse outcomes, and incidence of adverse reactions.


Compared with CG, the therapeutic effect in OG was observed to be evidently better, and its pain relief time and hemostasis time in the waist and abdomen were markedly shorter. After treatment, the whole blood high shear viscosity, FIB, RI, PI, and estrogen levels of both groups improved statistically compared with those before treatment, with more significant improvements in OG compared with CG. OG was also superior to CG with markedly lower incidence of preterm birth, miscarriage, neonatal adverse outcomes, and adverse reactions and a drastically higher full-term pregnancy rate.


Zishen Yutai pill combined with dydrogesterone tablets is of remarkable therapeutic effect in treatment of early threatened abortion, which can significantly improve clinical symptoms and pregnancy outcomes of patients, with a high safety profile, which is worthy of clinical application.
