Purpose: The primary aim of this secondary analysis is to assess the clinical utility of intrapartum ultrasound measurements of the fetal head-to-perineum distance (HPD) as a predictor for successful vaginal delivery.Methods: This secondary analysis was conducted on a cross-sectional study involving 33 pregnant women admitted for labor. HPD was measured using intrapartum ultrasound by certified sonographers. Additional variables such as age, BMI, and gestational age were also considered. Results: Our findings reveal a significant relationship between HPD and the occurrence of vaginal delivery. The odds ratio was calculated as 0.60 (95% Confidence Interval: 0.42-0.88), remaining significant after adjusting for other variables.Conclusion: In this secondary analysis, HPD measurements via intrapartum ultrasound were found to effectively predict the likelihood of vaginal delivery. This method offers a streamlined approach for labor management without sacrificing predictive accuracy.
