Patients should not be pregnant for 5 months and are recommended to be induced immediately. Before the induction procedure, the patient needs to go to the local family planning office to obtain a certificate and then the patient is recommended to be hospitalized for the induction procedure. Because this is the middle of the pregnancy, the fetus is larger and the risk of the induction procedure is higher. Before the induction of labor, it is important to complete the relevant tests, such as routine blood, coagulation, biochemistry, immunology, electrocardiogram and full chest X-ray, as well as routine white belt examination. After the procedure, patients are advised not to have intercourse for one month. In terms of diet, patients are expected to have a nutritious, high-protein diet and to abstain from cold, stimulating and spicy foods. It is normal to have a small amount of bleeding after surgery, and treatment should be symptomatic such as anti-infection and hemostasis.
