Placental adhesions can be dangerous as they may increase the risk of hemorrhage and other risks when clearing the uterus. Placental adhesion is the adhesion of placental villi to the surface of the myometrium and can be caused by high risk factors such as a history of multiple miscarriages and cesarean sections. Because of the tight adhesion between the placenta and the myometrium, there is a risk of hemorrhage and shock when removing the placenta during uterine evacuation, which needs to be done under the establishment of venous access and blood preparation, and operated by a professional doctor. The operation should be performed gently to avoid perforation of the uterus, and if necessary, it can be performed under ultrasound guidance. After the operation, uterine contractions should be applied in time to promote uterine contraction and reduce uterine bleeding. After the operation, the cleared tissues should be sent for pathological examination, and antibiotics such as tinidazole should be given as prescribed by the doctor to prevent infection, prohibit pelvic bathing and sexual intercourse for one month, and observe the vaginal bleeding situation, and repeat the examination on time.
