Abstract：Objective：To observe the clinical effect of the combination use of modified Danggui Shaoyao Powder， Oxytocin and Antibiotics on postpartum lochiorrhea with syndrome of qi deficiency and blood stasis. Methods：A total of 86 patients with postpartum lochiorrhea admitted to the People's Hospital of Yucheng County from April 2021 to April 2024 were selected and divided into the observation group and the control group according to the random number table method， with 43 cases in each group. With one case being excluded from the control group， finally 42 cases and 43 cases were respectively included in the control group and the observation group for study. Both groups received conventional treatment. The control group was additionally treated with Oxytocin combined with Cefradine Capsules， and the observation group was additionally treated with modified Danggui Shaoyao Powder based on the treatment of the control group. Both groups were treated for seven days. On the 15th day after treatment， the clinical effects were compared between the two groups. Before treatment and after seven days of treatment，the traditional Chinese medicine syndrome scores and uterine hemodynamics indexes [pulsitility index （PI） of uterine artery during systole， resistance index （RI） and peak systolic velocity （PSV）] were compared between the two groups. The duration of bloody lochia was compared between the two groups， and the amount of bloody lochia from the first day of treatment to the seventh day after treatment was recorded and calculated. The adverse reactions during treatment were recorded. Results：The total effective rate was 95.34% （41/43） in the observation group， higher than that of 78.57% （33/42） in the control group （P＜0.05）. After seven days of treatment， the traditional Chinese medicine syndrome scores in the two groups were reduced when compared with those before treatment，and the above scores in the observation group were lower than those in the control group （P＜0.05）；the RI and PI in the two groups were dwindled when compared with those before treatment，and RI and PI in the observation group were lower than those in the control group （P＜0.05）. The PSV in the two groups was fastened when compared with that before treatment，and the PSV in the observation group was faster than that in the control group （P＜0.05）. The duration of bloody lochia in the observation group was shorter than that in the control group， and the amount of bloody lochia from the first day of treatment to the seventh day after the end of treatment was less than that in the control group （P＜0.05）. There was no significant difference being found in the comparison of the incidence of adverse reactions during treatment between the two groups （P＞0.05）. Conclusion：The combination use of modified Danggui Shaoyao Powder， Oxytocin and Antibiotics can effectively improve the curative effect on postpartum lochiorrhea with syndrome of qi deficiency and blood stasis， relieve the symptoms， promote the recovery of the uterus，and enhance the uterine blood flow perfusion with great safety.
