Fetal anemia can be adequately tackled only if it is diagnosed on time. Fetal MCA-PSV has the potential to reliably predict fetal anemia. Scientific studies across the globe are a testimony to this fact. As such studies from rural setups are lacking, this study was initiated.
To demonstrate the normal values of fetal MCA-PSV at various gestational ages in an Indian setting by using the standard internationally accepted protocol.
Settings and design
The ultrasound wing of radiodiagnosis department of a rural medical college was the site of this study. Permission from institutional research cell and ethical committee was obtained for study on fetal MCA-PSV. Written informed consent from every pregnant mother who participated in the study was also obtained. A cross-sectional and prospective observational study was conducted over the last 9 months.
Materials and methods
A total of 60 measurements of fetal MCA-PSV were conducted in normal 20 pregnant women referred for routine obstetric scan at 12, 24, and 36 weeks of gestation respectively, by a single radiologist on color Doppler ultrasound machine. In each fetus the proximal MCA, soon after its origin, was evaluated.
The observations were entered in Microsoft Excel sheet and statistical analysis was done by using SPSS statistical software version 12. The relation between fetal MCAPSV and gestational age was studied using the Karl Pearson's correlation coefficient. The significance of difference was studied using the t-test.
MCA-PSV increased with increasing gestational age, suggesting positive correlation between the two. Better waveforms and increasing PSV were visualized with advancing gestational age.
Fetal anemia can be accurately predicted only if the MCA-PSV is scientifically measured and compared with normal values in a given setting. This study demonstrates the normal values at various gestational ages in an Indian setting.
