ABSTRACT
Objective:
The aim of this study is to assess the impact of maternal supine and left lateral positions using umbilical artery resistance measurements.
Material and Methods:
38 pregnant women between 28-40 weeks were included in the prospective observational study. Umbilical artery resistance index was measured using doppler ultrasound.
Results:
The average resistance index in the supine position was 0.03 units higher than the measurement taken while in left lateral position. This difference is statistically significant (p=0.007).
Conclusion:
There is higher umbilical artery resistance in the maternal supine position compared to the maternal left lateral position.
