Inducing labor medically at 16 weeks does not necessarily necessitate evacuation of the uterus, it depends on the individual. After induction of labor, the uterus is relatively clean and does not need to be cleared. After induced labor, when there is excessive residue, removal of the uterus is required. At 16 weeks of pregnancy, induction of labor is usually necessary due to the large size of the fetus. After inducing labor by drugs, if there is no residue in the uterine cavity or the residue is small, usually there is no need to clear the uterus, and you can promote uterine contraction by taking motherwort granules, etc., so that the residue in the uterine cavity can be discharged. After drug induced abortion, more residues in the uterine cavity, or when the use of medication does not have much effect, should consider purging the uterus, because a long time without purging the uterus, the residual tissue may cause poor uterine contraction vaginal bleeding, infection or coagulation dysfunction, serious cases cause hemorrhage. Therefore, whether to clear the uterus or not after 16 weeks of pregnancy drug induced abortion should be decided according to their own situation. Pregnant women must follow the doctor’s instructions, safe and reasonable use of medication, and after the removal of the uterus, to do a good job of care, to prevent the emergence of abnormalities.
