Usually, induction of labor usually requires a hospital stay of about 5 days. Induction of labor is the termination of pregnancy after 14 weeks of pregnancy, because the fetus is already formed and hemorrhage and obstructed labor may occur during delivery, and cannot be induced in an outpatient setting. For inpatient induction of labor, first of all, you need to have a comprehensive physical health, including blood routine, coagulation function, urine routine, white belt routine, liver and kidney function, hepatitis B, hepatitis C, syphilis, AIDS, electrocardiogram, chest X-ray, etc. If the test results are normal, intra-amniotic injection of Ravnol drug can be given, and abdominal pain will usually occur in 24 hours, and then the fetus placenta will be delivered. A follow-up ultrasound is required 24-48 hours after delivery to check the recovery of the uterus and the presence of placenta and membranes, and a total hospital stay of about 5 days is required. If there is heavy bleeding or other abnormalities during the induction of labor, the hospital stay may be extended. After the induction of labor, it is necessary to pay attention to rest and nutrition, and not to have sexual intercourse for 1 month.
