“…Epidural increased the median of the second stage by approximately 80 min, and the 95th percentile by approximately 35 min. This is in contrast to a previous report that noted a 4‐h increase both in the median and in the 95th percentile in the second‐stage length 13 . Another report also demonstrated doubling of the 95th percentile of second‐stage duration with epidural from 1.7 h to 3.3 h 22 and only a 1‐h increase in the median of second‐stage duration.…”

“…It seems reasonable to consider women undergoing VBAC as nulliparous with regard to second‐stage duration, despite the 20‐min difference found in our study between VBACs and nulliparous deliveries. This finding is in line with previous reports that VBAC with no prior vaginal delivery resembles nulliparous deliveries more than secundiparous deliveries 12,13,22 …”

“…Our primary finding that second‐stage duration does not vary by primary CD timing is in contrast to the only publication regarding the mode of prior CD and duration of second stage, which concluded that the duration of a VBAC's second stage of labor was significantly longer in women with a previous second‐stage CD, compared with a planned or a first‐stage CD 13 . It is difficult to explain the difference between both studies and this difference is probably not the result of sample size limitations, as our study cohort was larger.…”

“…A recent study concluded that CD at the second stage of labor is associated with a longer second stage in subsequent VBAC 13 . However, that study was performed at two medical centers, which might have introduced different practice bias, used incomplete data of maternal anthropometric measurements, and or did not account for other factors associated with VBAC or reported maternal or neonatal outcomes.…”

Objective To characterize the length of the second stage of labor among women completing a first vaginal birth after a cesarean (VBAC), according to the stage of labor during primary cesarean delivery (CD). Methods A retrospective cohort study of VBACs between 2011 and 2020. Study groups were divided as follows: CD not in labor, CD in the first stage of labor, and CD in the second stage of labor. The primary outcome was the length of the second stage. Results A total of 1310 VBACs were included. The timing of the primary CD was not associated with the duration of the second stage. The median second stage of duration of VBACs with previous first stage CD versus previous CD not in labor was 81 versus 106 min, respectively (P = 0.050). In multivariable linear regression, maternal age, birth weight, and epidural were independently associated with second‐stage length. Maternal and neonatal outcomes did not differ between study groups and were not affected by the second‐stage length. Conclusion When stratified according to the labor stage of the primary CD, second‐stage duration among women completing VBACs was not associated with labor stage at the primary CD. Extremes of the second‐stage duration were not associated with increased morbidity.
