Defining fetal station

This study was undertaken to determine the definitions and beliefs regarding fetal station among pregnancy caregivers. Residents, nurses, and faculty at 5 teaching centers in Denver, Colo, were given surveys to determine what definitions were being used for fetal station and the perceived importance of these definitions. There were 243 responses from the 453 surveys. We found 4 definitions were in use: level of the presenting part in relationship to ischial spines in (1) centimeters or (2) thirds, and level of the biparietal diameter in relationship to the ischial spines in (3) centimeters or (4) thirds. Few caregivers were aware that other caregivers were using different definitions of fetal station. This lack of standardization may lead to errors in the care of laboring patients.
