Value of partogram in vaginal birth after caesarean section.

A prospective partographic study of labour in 102 women with one previous lower uterine segment caesarean section in the Aminu Kano Teaching Hospital, Kano, Nigeria, was carried out to assess the predictive value of partogram on the outcome of labour in vaginal birth after caesarean section (VBACS). The outcomes measured were the duration of labour, cervical dilatation rate (CDR), and average cervical dilatation rate (ACDR). The data obtained were analysed using Z-test and tests of validity. A successful vaginal delivery rate of 72.5% was achieved. The cervical dilatation rate, average cervical dilatation rate and the alert line were found to be significant predictors of the outcome of labour in VBACS. These findings have important implications in establishing policies for monitoring labour in VBACS.
