Importance and Significance of Knee-Chest Decubitus Position of the Pregnant Women, in the Delineation of Fetal Facial Imaging with Four-Dimensional Color Doppler Ultrasound

Abstract

Objective: To investigate and validate the role of the Knee-chest Decubitus position in fetal facial feature delineation by 4D Ultrasonography. Methods: Pregnant women were randomly divided into two groups: One group underwent knee-chest decubitus position prior to re-examination, and the second group underwent free activities like walking for 5, 15 or 30 minutes followed by a re-examination of the fetus. The acceptability of the fetal facial images following the two above mentioned activities was compared. Results: The Knee-chest Decubitus position was identified to be a more successful procedure for obtaining acceptable images. Additionally, it improved the fetal position and the resulting images were achieved significantly rapidly by this maneuver compared to free movement. Conclusion: The knee-chest decubitus position is simple, easy, safe and fast and thus of great convenience and promising for pregnant women.
