ABSTRACT

Background: Spontaneous abortion is a common complication during the initial periods of pregnancy, which has an impact on the subsequent pregnancies also. Hence this study was conducted to assess the obstetric outcome of mothers who had previous spontaneous abortion, with respect to their gravid and also to compare with those who has no history of spontaneous abortion. Methods: This cohort study was carried out in the Institute of Obstetrics and Gynecology at Madras Medical College, Chennai during October 2016 to October 2017. A total of 1000 cases with 500 patients with history of spontaneous abortion and 500 controls without history of spontaneous abortion were included in the study. The study was conducted using a proforma and data analysis was done using Statistical Package for Social Sciences. Results: Number of patients who reached full term among control group was 93.4% and cases were 64.6% (p≤0.001). The number of patients who had previous abortions had a significantly lesser chance of continuing the pregnancy to full term. Number of patients who delivered preterm among control group was 6.2% and among cases were 17.2% (p≤0.001). Conclusion: There was significant association between previous spontaneous abortion and preterm delivery, recurrence of abortion and PROM, in the subsequent pregnancies. There was no statistically significant increase in the rate of IUGR, still birth, IUD in the subsequent pregnancies. Thus careful surveillance is required in pregnancies following recurrent abortions, for early detection of complications.
