Design outcomes

Primary

MeasureTime frame
Birth by caesarean section collected on the case report form (CRF) at the birth of baby

Secondary

MeasureTime frame
Maternal outcomes: 1. Epidural use during labour and birth collected on the CRF at the birth of baby 2. Duration of the second stage of labour (between full dilation to the birth of the baby) collected on the CRF at the birth of baby 3. Duration of the third stage of labour (between the birth of the baby to the expulsion of the placenta and membranes) collected on the CRF at the expulsion of the placenta and membranes 4. Time from randomisation to birth (mins) collected on the CRF at the birth of baby 5. Time from induction of labour (induction of labour is defined as the process by which labour is started prior to its spontaneous onset by progressive cervical effacement and dilatation and/or artificial stimulation of uterine contractions, leading to active labour and birth) to birth (mins) collected on the CRF at the birth of baby 6. Mode of birth (spontaneous vaginal birth, instrumental or caesarean section) collected on the CRF at the birth of baby 7. Degree of perineal trauma collected on the CRF at the birth of baby. Defined as follows: 7.1. First degree, injury to skin only 7.2. Second degree, injury to the perineal muscles but not the anal sphincter 7.3. Third degree, injury to the perineum involving the anal sphincter complex: 7.3.1. 3a, less than 50% of external anal sphincter thickness torn 7.3.2. 3b, more than 50% of external anal sphincter thickness torn 7.3.3. 3c, internal anal sphincter torn 4. Fourth degree, injury to the perineum involving the anal sphincter complex (external and internal anal sphincter) and anal epithelium. 8. Reason for, and grade of caesarean section (immediate threat to the life of the woman or fetus, maternal or fetal compromise which is not immediately life-threatening, no maternal or fetal compromise but needs early delivery, or delivery timed to suit woman or staff) collected on the CRF at the time of caesarean section 9. Confirmed urinary retention requiring catheterization collected on the CRF at discharge from hospital 10
