Abstract
Objective: To study the efficacy of 1st trimester ultrasound parameters for prediction of early miscarriage. Method: A prospective observational study was undertaken to study the efficacy of early ultrasound parameters for prediction of early miscarriage in Tata Main Hospital, Jamshedpur, India. Result: Of the 800 pregnancies studied, 140 had early miscarriage. Crown Rump length (CRL), Gestation Sac Diameter (GSD), Fetal Heart Rate (FHR) values less than 5th percentile (OR: 26.48, 26.94, 100.63, respectively) and Yolk Sac Diameter (YSD) more than 95th percentile (OR: 1.04) were significant predictors of early miscarriage. When these abnormal parameters coexisted in any pregnancy, the miscarriage risk was significantly high (OR: 35.27). A normal YSD could not significantly reduce the risk of miscarriage, if the other three parameters were below the 5th percentile (OR: 35.27). Every 10 beats per minute (bpm) decrease in FHR below 130, there was a 26.73% increase in risk of miscarriage. GSD-CRL difference <5 mm was associated with significantly increased miscarriage risk (OR: 4.88). Conclusion: Early ultrasound measurements of CRL, GSD, FHR and YSD are good predictors of early miscarriage and tables using various combinations of abnormal parameters may improve the prediction rates.
