RESUMO

The purpose of this study was to identify medical and non-medical factors associated with the trial of labourand with vaginal delivery among primipara women with one previous Cesarean section and to compare them with the attitudes and practices reported by obstetricians from the city. The study was divided into two parts: the first corresponded to a nested case control study, on wich a secondary data analysis, of an original retrospective cohort study was carried out on a population of women who delivered their first child during the year of 1985 in the city of Campinas. The second part was a mail survey carried out on ali obstetricians of . the city with regards their attitudes and practices concerning the trial of labour in pregnant women with one previous Cesarean section. The factors identified as statistically associated to the trial of labour and to a vaginal delivery in these conditions were: monthly family income lower than 5 minimum wages, medical health care through the Brazilian NHS, low maternal age and first Cesarean section indicated by either breech presentation, twins or transverse situation of the fetus. Among those women who also had a Cesarean section in the second delivery, only 11% had undergone a trial of labour. Bas(i)d on the survey, around 80% of obstetricians stated they not only agree with but also practice the trial of labour reporting, for their last case similar to this, vaginal delivery in 50% of the cases. It can be concluded that the main determinants for performing a trial of labour and a vaginal gelivery among women with one previous Cesarean section were social and economic factors. According to the obstetricians questioned the trial of labour would be a safe alternative of conduct for these women, and the success to a vaginal delivery occurs in around 50% of the cases, which is nonetheless completely different from what is observed in practice
