A Prospective Study of Cerebroplacental Ratio Assessment in Low-Risk Term Pregnancy and Its Effect on Maternal and Fetal Outcome.

Objective: - To study CP ratio & its correlation with feto -maternal outcome. Methods: - This was a prospective observational study done in Department of Obstetrics and Gynaecology, MGM Medical college, Indore, over a period of one year. Women > 37-week singleton pregnancy with no known risk factor who had Doppler USG done at the time of labor were included. CPR was calculated by dividing the Doppler indices of middle cerebral artery (MCA) by umbilical artery (MCA PI/UA PI). CPR < 1 was taken as abnormal. Results: - Out of 150 low risk term pregnancy who went for USG colour doppler Scan, 14 (9%) patients were having CPR <1 and 136 (90.6%) were having CPR >1. Among 14 patient with CPR <1, 10 (71%) were delivered by caesarean section as compared to only 6 (4.41%) patients with CPR >1. Among 14 patient with CPR <1,13 (92.86%) had adverse outcome as compared to only 11.76% patients with CPR >1. Conclusion: - Our study found CPR measure to be a very promising tool for optimising the identifcation of at-risk foetus in low-risk AGA pregnancies. [ABSTRACT FROM AUTHOR]
