Abstract
BACKGROUND
Numerous variables are linked to the success of vaginal delivery, including the subpubic arch angle (SPAA) during labor, the importance of which has not yet been fully elucidated.
AIM
To examine the SPAA distributional characteristics and to ascertain SPAA’s ability to predict the type and duration of labor.
METHODS
We determined the SPAA and analyzed the corresponding data. We also evaluated the relationship between the SPAA and the mode of delivery and the duration of labor by regression. The present study comprised a total of 301 pregnant women who had given birth at Beijing Tiantan Hospital of the Capital Medical University between January and December of 2021.
RESULTS
Our analysis of 301 pregnant women revealed that the SPAA measured using three-dimensional trans-perineal ultrasound had a minimum angle of 81° and a maximum angle of 122.2°. The angle in the normal vaginal delivery group was greater than that in the labor cesarean group (P = 0.000). The SPAA was a highly significant positive predictor of normal vaginal delivery (P = 0.000) with an area under the curve of 0.782 (P = 0.000; 95%CI: 0.717–0.848). We found the length of the second stage of labor to be positively influenced by the SPAA using linear regression analysis (P = 0.045).
CONCLUSION
The SPAA was a highly significant positive predictor of normal vaginal delivery. The length of the second stage of labor and normal vaginal birth were predicted by SPAA.
Core Tip: We adopted three-dimensional trans-perineal ultrasound to examine the subpubic arch angle (SPAA) distributional characteristics, and to ascertain the SPAA’s ability to predict the length of the second stage of labor and normal vaginal birth. We herein provided a noninvasive, low-cost tool to reduce the number of emergency cesarean deliveries conducted during labor.
