Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this observational study is to assess the effect of early labour analgesia on obstetric and neonatal outcomes in induced labour in primiparous women with a full-term pregnancy whose labour was induced with a Cook balloon or prostaglandins.

It aims to answer whether early labour analgesia (\< 4 centimetres of cervical dilation) prolongs the duration of labour. Secondary outcomes will be Incidence of caesarean section, use of oxytocin, onset of fetal heart rate abnormalities within 30 minutes of augmentation, incidence of episiotomy, amount of blood loss, need for epidural catheter repositioning due to inadequate analgesia, onset of breakthrough pain defined as need for "rescue" top-ups within 60 minutes of previous top-ups, Apgar score (at 1 and 5 minutes), neonatal umbilical pH and neonatal intensive care unit admission. Patients who received early partoanalgesia were compared for the proposed outcomes with patients who received partoanalgesia in active labour (cervical dilation \> 4 centimetres).
