Objectives: To evaluate the clinical significance of the head progression distance (HPD), measured by trans- perineal ultrasound, during prolonged second stage of labor. Methods: This is a prospective study of women, at 37 or more weeks of gestation, with failure to progress in the second stage of labor. Trans-perineal ultrasound examination was performed during pushing, with an empty urinary bladder, by a single operator, who was blinded to the results of the digital examination. The HPD measurement was defined as a vertical line that connects the infrapubic line to the lowest part of the bony skull. Associations were examined between HPD and digital examination of the fetal head station, feto- maternal characteristics, modes of delivery, and perinatal outcomes. Results: Sixty-six patients in prolonged second stage of labor participated in the study. Seventeen (25.7%) delivered by spontaneous vaginal delivery, 38 (57.5%) by instrumental vaginal delivery, and eleven (16.8%) by CS. The overall mean HPD was 6.50 cm ( ± 1.35, CI 95% 6.16-6.83). HPD did not associate with head positions or mode of delivery, but correlated positively with fetal head station and neonatal head circumference measured after delivery. Logistic regression and receiver-operating curve analysis demonstrated a non significant value of HPD, during prolonged 2(nd) stage, in predicting mode of delivery. Conclusion: Although HPD in prolonged second stage labor could not predict mode of delivery, it may be used as an ancillary tool for fetal head station assessment. Copyright © 2013 ISUOG.
