Cesarean section is currently the main method for termination of pregnancy with central placenta praevia. However, because the attachment site of placenta praevia is in the lower part of uterus, even covering the cervical opening, which is adjacent to the vertical branches of uterine artery and vaginal artery, the blood vessels and blood sinuses are very rich, and there are relatively few smooth muscles in the lower part of uterus, mainly composed of connective tissue, so the contraction force of smooth muscle fibers is poor and the contraction effect is weak, which makes the hemostatic function of blood sinuses on the meconium surface relatively insufficient, so hemorrhage on the abruptive surface of placenta can occur and is difficult to Therefore, hemorrhage at the placental abruption surface can occur and is difficult to control. In the past, the common treatment was to strengthen uterine contraction, ligate the open blood sinus of the lower uterine detachment surface with figure-of-eight sutures, caulking the uterine cavity, etc. If necessary, bilateral superior uterine artery branches, bilateral internal iliac artery ligation and uterine compression suturing were feasible. However, the lower uterus receives blood supply from the cervical artery (lower branch of the uterine artery) and the vaginal artery, so conventional ligation of the superior branch of the uterine artery has no significant effect. Only ligation of the internal iliac artery is possible to achieve control of bleeding from the abruptive surface of the placenta, but ligation of the internal iliac artery is difficult and prolonged, eventually forcing a hysterectomy. Uterine tamponade is a more traditional method of hemostasis and has been advocated in recent times for patients with intractable bleeding during cesarean section. However, some scholars believe that the bleeding mainly comes from the lower uterine segment which lacks the ability to contract on its own and is flaccid, so gauze stuffing is not easy to stop the bleeding, and if the gauze stuffing is not tight, it will hide the truth of uterine bleeding, but if it is too tight, it will affect the contraction of the uterus itself and intensify the bleeding, and in addition, it is easy to develop postoperative infection. There are other methods to stop bleeding by filling the uterine cavity with Foley catheter and three-lumen balloon tube, but they are less used in China. Uterine compression sutures are a series of new methods used to treat postpartum hemorrhage, including B-Lynch sutures and Cho sutures, etc. The principle is to stop hemorrhage by mechanically compressing the arch vessels of the uterine wall so that the blood flow is significantly reduced and slowed down, and local thrombosis is formed, and also stimulate the uterus to contract to further compress the blood sinuses and stop hemorrhage. However, uterine compression suturing is more effective for bleeding caused by simple lack of contraction. Selective arteriographic embolization has a 97% success rate for postpartum hemorrhage, but it is only indicated for patients whose vital signs are stable and can be moved, and it requires personal skills and special equipment and is expensive. Its complications mainly include post-embolization ischemia and pelvic infection. This study summarizes the following experiences in preventing hemorrhage during cesarean section for central placenta previa: (1) If the placenta is attached to the anterior and lateral walls of the lower uterine segment, making a transverse incision is likely to cause hemorrhage, especially if the hole is made in the placenta is more likely to cause artificial hemorrhage. We advocate a longitudinal incision in the body of the uterus. In other words, a small incision of 3cm should be made in the body of the uterus first, and then it should be extended upward and downward respectively to reach the place which is favorable for the delivery of the fetus, and to avoid damaging the placenta when extending downward, and sometimes even if the placenta is touched, it should be controlled at its edge, so that the bleeding will not be too much. (2) Uterine artery ligation should be performed immediately after routine treatment such as promoting uterine contraction and local suturing. The standard for postpartum hemorrhage after cesarean delivery is 500 ml of bleeding after delivery, but it is usually too late to treat the bleeding when it has reached 500 ml. We believe that when the bleeding amount reaches 200ml, we should be alert to the possibility of postpartum hemorrhage, and the treatment to prevent hemorrhage should be one step earlier. (3) Because the ureter rises with the right rotation of the uterus and the extension of the lower uterine segment in late pregnancy, and transposes forward, the position of the bladder base is also higher than normal, and the lower uterine segment is congested and edematous during pregnancy, so routine uterine artery ligation can easily damage the ureter and bladder. Both uterine arteries have two main branches, upper and lower, which travel along the lateral wall of the uterus and send out vertical branches, i.e., the arcuate artery, to penetrate the uterine wall and travel in the outer and middle 1/3 of the myometrium. We perform multiple intrafascial uterine artery sutures, intermittently suturing the entire muscle layer of the lateral wall of the uterus and the branches of the uterine artery within it, which provides reliable hemostasis, is simple and easy to perform in the uterine cavity, does not penetrate the plasma layer of the uterus, therefore does not damage the ureter or bladder, does not cause hematoma in the broad ligament, and can simultaneously suture the lower branches of the uterine artery below the incision, eliminating the need to separate the bladder for the lower branches of the uterine artery through the vagina. It can effectively stop the bleeding of the lower uterine segment caused by the placental detachment surface during central placenta praevia surgery. In conclusion, multiple intrafascial uterine artery sutures are clinically effective in controlling bleeding during intrauterine delivery of central placenta praevia, and can effectively reduce the hysterectomy rate, which is easy to apply and worthy of clinical promotion.
