Abstract：Objective To investigate the effect of Chanfuxin combined with Baogong Zhixue granules on the du-ration of bloody lochia and uterine involution after cesarean section for placenta previa.Methods A total of 80 pregnant women with placenta previa who underwent cesarean section in our hospital from January 2022 to December 2023 were se-lected and divided into the control group(n=40)and the observation group(n=40)by random envelope method.The control group was treated with Baogong Zhixue granules and oxytocin,and the observation group was treated with Chanfuxin granules on the basis of the control group.Both groups were treated for 7 d and followed up for 42 d.The uterine recovery(postpartum hemorrhage,duration of bloody lochia and end time of lochia),height of fundus recovery,the sum of three uterine diameters,effect of uterine involution and adverse reactions were compared between the two groups.Results The amount of postpar-tum hemorrhage in the observation group was less than that in the control group,and the duration of bloodylochia and the end time of bloody lochia in the observation group were shorter than those in the control group(P<0.01).The decrease in the height of fundus recovery in the observation group was greater than that in the control group at 3 d and 5 d after delivery(P<0.01).The sum of the three uterine diameters in the observation group was lower than that in the control group at 42 d after delivery(P<0.05).The effect of uterine involution in the observation group was better than that in the control group[97.50%(39/40)vs.82.50%(33/40)](P<0.05).There was no significant difference in the incidence of adverse reactions between the two groups[12.50%(5/40)vs.7.50%(3/40)](P>0.05).Conclusion Chanfuxin combined with Baogong Zhixue granules can alleviate postpartum hemorrhage in patients with placenta previa after cesarean section,shorten the duration of bloody lochia,promote uterine contraction,and accelerate the process of uterine involution,showing good safety.
