Abstract

The maximum cervical dilatation achieved by parturients who went through labour prior to their primary caesarean births were related to the mode of delivery in the subsequent birth to ascertain if there is a link between the two. The success rates of vaginal births after primary Caesarean sections (VBAC) for arrest and non-arrest disorders were also compared using information derived from the birth records of the hospital. The success rate for VBAC was significantly high in subjects whose primary caesarean sections were for non-arrest disorders compared to those who had arrest disorders (73.3% versus 55.6%; x2 = 5.25, p = 0.02). The maximum cervical dilatation reached before primary caesarean section did not significantly affect the success rate of VBAC in the subsequent delivery (x2 [trend] = 0.78, p = 0.68). Patients who had primary caesarean section for arrest disorder require full evaluation before being allowed to attempt vaginal birth in a subsequent pregnancy but the maximum cervical dilatation reached before primary caesarean section need not be factored into a decision for VBAC.
