بررسی اثرات 1 نوبت سقط خودبه‌خودی بر سرانجام بارداری بعدی

The objective of the present study was to determine the pregnancy outcome following one previous spontaneous abortion. A randomized prospective historical cohort study was done on 300 patients. 200 patients were gravida 2 and their previous pregnancy was spontaneous abortion and 100 patients(control group) were gravida 2 but their previous pregnancy was term pregnancy with a live fetus. Then, pregnancy outcomes including maternal complications such as(placenta praevia, placenta abruptio, PROM, preeclampsia and eclampsia, abortion, breech presentation, preterm labor, intra uterine fetal death and neonatal complications(low birth weight, visible congenital malformations, low Apgar Score minute 1) and delivery route such as cesarean section or instrumental delivery(forceps or vacuume) were determined. Statistical analysis showed that pregnancy complications following one previous spontaneous abortion were not different from that of control group except for abortion and intrauterine fetal death, which was more than control group. Also, the rate of cesarean section and curetage had been increased. Neonatal complications did not have significant statistical difference in comparison with control group. In conclusion, one prior spontaneous abortion is not a very significant risk for next pregnancy, but the risk of abortion and IUFD will increase. Therefore, careful prenatal care is mandatory.
