Miscarriage does not necessarily require hospitalization. If the abortion is said to be in a small month and the ultrasound indicates that the size of the gestational sac is 1.5 cm, the abortion can be performed on an outpatient basis and does not require hospitalization. However, before miscarriage, blood cell analysis, coagulation analysis and electrocardiogram should be performed and these tests should be normal before miscarriage can be performed. If the gestational sac is large and the month of pregnancy is already large, hospitalization is needed in this case because during the abortion process, if the month is large it is easy to have hemorrhage and hospitalization allows for timely blood transfusion, blood preparation, etc. and it will take longer. Generally speaking, most abortions also require blood cell analysis, coagulation analysis, liver function, kidney function, virus eight, blood type, electrocardiogram, and gynecological ultrasound after hospitalization, and the results of these tests are not abnormal, and contraindications to abortion are ruled out. In the process of miscarriage, if heavy bleeding occurs, timely curettage should be performed. If there is no heavy bleeding, the embryo will be expelled after 24-48 hours of intra-amniotic injection of epsha acridine.
