Brief Summary

Lumbar epidural analgesia is the most used method for reducing labour pain, but its impact on the duration of the second stage of labour and on neonatal and maternal outcomes remains debated. The aim was of the study is to examine whether epidural analgesia affects the course and the outcomes of labour among patients divided according to the Robson-10 group classification system. Patients of Robson's classes 1, 2a, 3, and 4a were divided into either the epidural analgesia group or the non-epidural analgesia group. A propensity score matching analysis was performed to balance intergroup differences. The primary goal was to analyse the duration of the second stage of labour. The secondary goals were to evaluate neonatal and maternal outcomes.

Outcome Measures

Primary Outcomes (1)

  • Lenght of 2nd stage

    Evaluate the length of the second stage of labour

    From the time of the first documented full cervical dilatation to delivery

Secondary Outcomes (2)

  • Foetal Outcome

    At 1 and 5 minutes after birth

  • maternal outcome

    2 hours after the delivery.

Study Arms (2)

Epidural Analgesia

Procedure: Epidural Analgesia

No analgesia

Interventions

Using an aseptic technique while the patient is in sitting position, an epidural catheter was placed at the L2-L3 or L3-L4 interspace. Analgesia was established with the epidural administration of a low dose of local anaesthetic, plus a lipid-soluble opioid (ropivacaine 0.1% and sufentanyl 0.5%, 20 mL). Analgesia was maintained with a top-up regimen, using intermittent manual epidural boluses of increasing concentrations of ropivacaine, with up to 0.15% at full dilation, according to specific needs of individual participants.

Gender Eligibility DetailsPregnant women
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

A retrospective cohort analysis was performed of all live, at term (37-42 weeks) vaginal deliveries at a tertiary university hospital over an 11-year period (October 2008 to October 2019). This population was divided according to the RTGCS. Pregnant patients were enrolled according to the following RTGCS groups: R1 (nulliparous, single cephalic full-term pregnancy with spontaneous labour); R2a (nulliparous, single cephalic full-term pregnancy with induced labour); R3 (multiparous, single cephalic full-term pregnancy with spontaneous labour); and R4a (multiparous, single cephalic full-term pregnancy with induced labour).

You may qualify if:

  • pregnant women,
  • at term (37-42 weeks),
  • admitted to a tertiary university hospital over an 11-year period (October 2008 to October 2019)

You may not qualify if:

  • multiple pregnancies,
  • known major fetal or chromosomal abnormalities,
  • pre-labour Caesarean deliveries,
  • elective Caesarean deliveries.
