We absolutely love when new research confirms what we already knew 🫶🏻
The impact of parity on uterine rupture in patients with and without a previous cesarean delivery: a retrospective analysis of risk variation in women with and without a previous cesarean delivery - Probability of uterine rupture by number of previous VBACs
This graph illustrates the probability of uterine rupture during vaginal delivery attempts in women with 1 previous cesarean delivery, stratified by the number of previous VBACs. The x axis represents the number of previous VBACs (0 to≥5), and the y axis shows the corresponding rupture rate. Women with no previous VBAC had a uterine rupture risk of 0.64%. This risk decreased to 0.28% after 1 previous VBAC and continued to decline with additional VBACs, reaching 0.18% among those with 4 VBACs. Notably, no cases of uterine rupture were observed in women with 5 or more previous VBACs. A logistic regression analysis demonstrated a statistically significant inverse association between the number of previous VBACs and the risk for uterine rupture (P
