What this trial studies

This observational cohort study evaluates the safety and outcomes of two delivery options for women with one previous caesarean: trial of labour after caesarean (TOLAC) and elective repeat caesarean delivery (ERCD). The study aims to determine if TOLAC is non-inferior to ERCD in terms of perinatal morbidity and mortality rates. Additionally, it will assess various maternal and infant health outcomes, including satisfaction, quality of life, and the risk of postnatal depression. Data will be collected through questionnaires and follow-ups at multiple time points postpartum.

Who should consider this trial

Good fit: Ideal candidates are pregnant women aged 18 or older, with a singleton pregnancy and one previous caesarean delivery, who are admitted to the labour ward at 34 weeks gestation or later.

Not a fit: Patients who have multiple pregnancies, more than one previous caesarean, or those who do not understand French may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide evidence to support safer delivery options for women with a history of caesarean, potentially reducing risks associated with repeat surgeries.

How similar studies have performed: Previous studies have shown mixed results regarding TOLAC safety, but this study aims to address limitations in existing literature, making it a novel approach.
