To explore the application effect of Anleike combined with modified B-lynch suture for treating hemorrhage of women with placenta previa during cesarean section, and to analyze the related pregnancy outcomes of these women. Methods: A total of 120 women with placenta previa and hemorrhage during cesarean section were prospectively selected and were divided into two groups (60 cases in each group) according to the random number table method from June 2019 to June 2022. The women in the control group were given routine treatment, and the women in the study group were given treatment of Anlex combined with modified B-lynch suture. The surgical indicators, curative effects, ovarian function indicators, complications rate, and the pregnancy outcomes of the women were compared between the two groups. Results: The intraoperative bleeding loss (367.4±94.4 ml), the postoperative 2h bleeding loss (256.4±72.4 ml), and the postoperative 4h bleeding loss (312.3±89.7 ml) of the women in the study group were significantly less than those (498.5±102.7 ml, 448.1±82.3 ml, and 529.2±2.9 ml) of the women in the control group. The time of hospitalization (8.4±2.3d) of the women in the study group was significantly shorter than that (13.9±3.6d) of the women in the control group. The total effective rate (93.3%) of the women in the study group was significantly higher than that (70.0%) of the women in the control group. The levels of estradiol (E2) and antimullerian hormone (AMH) of the women in both groups had decreased significantly, while the levels of luteinizing hormone (LH) and follicle stimulating hormone (FSH) of the women in both groups had increased significantly, and the change ranges of which of the women in the study group were significantly higher than those of the women in the control group. The incidences of hysterectomy (1.7%), blood transfusion (51.7%), postoperative abdominal pain (8.3%), and total complications (13.3%) of the women in the study group were significantly lower than those (11.7%, 70.0%, 21.7%, and 35.0%) of the women in the control group (P＜0.05). Conclusion: Anlek combined with modified B-lynch suture for treating hemorrhage of the women with placenta previa during cesarean section has significant effect, which can effectively decrese their volume of the postoperative bleeding, improve their ovarian function and pregnancy outcomes, reduce the incidence of their postoperative complications, and promote their recovery.
