Evaluate The Effectiveness of Cerebroplacental Ratio in Predicting Neonatal Outcome in Low Risk Pregnancies with Reduced Fetal Movement in Third Trimester

Abstract Introduction: Antepartum stillbirth significantly contributes to perinatal mortality, surpassing deaths from prematurity and sudden infant death syndrome. Aim: To evaluate the effectiveness of CPR in predicting neonatal outcomes in low-risk pregnancies with RFM. Methodology: This hospital-based cross-sectional study will be conducted in the Department of Obstetrics and Gynecology at PBM Hospital, Bikaner, over a duration of one year, from September 2023 to August 2024. Result: In our study of 300 cases, the majority were aged 19-25 years (69.67%), with 57.33% being primigravida; mean UAPI and MCAPI were 0.81 ± 0.41 and 1.07 ± 0.60, respectively; CPR was <1.1 in 15% of cases; 93.75% of non-reassuring fetal status cases with CPR ≤1.1 were delivered by LSCS; live birth rates were 97.77% for CPR ≤1.1 and 99.21% for CPR >1.1; 80% of CPR ≤1.1 cases had normal weight, and mean birth weights were 3.14 ± 0.53 kg for CPR ≤1.1 and 3.20 ± 0.61 kg for CPR >1.1; NICU admissions showed APGAR ≤7 in 50% of CPR ≤1.1 and 58.06% of CPR >1.1 cases, with significant findings regarding birth weight differences. Conclusion: This study of 300 low-risk term subjects concluded that low CPR is not significantly linked to increased obstetric interventions or adverse perinatal outcomes, but further large randomised trials are necessary for its clinical application.
