Pre-eclampsia can be kept in labor until close to the expected date of delivery at most, but the details need to be judged according to the physical condition of the pregnant woman and the severity of the disease. If the patient’s condition is stable and the blood pressure has been controlled through treatment, and there is no persistent elevation of urinary protein or complications, the pregnancy is usually kept alive until the woman is close to her due date. However, if the patient’s condition has progressed to severe preeclampsia with complications that threaten the health of the mother and fetus, a cesarean section is usually needed to end the pregnancy about 48 hours after fetal lung maturation. Pregnant women with preeclampsia are advised to seek timely medical attention, complete the relevant examinations and monitor the progress of the disease.
