患者教育视频：屈大腿助产法

This video, created by Nucleus Medical Media, shows how clinicians use the McRoberts Maneuver to release a baby's shoulder from impingement on the mothers pubic symphysis during birth. The mother's legs are flexed toward her shoulders as she lays on her back to expand the pelvic outlet. A ghosted view of the mothers pelvis shows the baby's shoulder releasing from the pubic symphysis. Music: Prelude from Bach's Cello Suite No. 1 in G major
