About this study

Official title: Programmed Intermittent Epidural Bolus Versus Continuous Infusion When Added to Patient-controlled Epidural Analgesia on Bupivacaine Consumption in Labour Analgesia: a Randomized Controlled Trial

This study aims to establish if programmed intermittent epidural bolus combined to patient controlled analgesia in labour analgesia will lower the hourly bupivacaine consumption when compared to continuous infusion combined with patient controlled analgesia. The investigators' hypothesis is that the use of programmed intermittent epidural bolus will lower the hourly bupivacaine consumption.

Read the detailed description

Patients are randomised to receive either a programmed bolus of 6ml each 45 minutes or a continuous infusion of 8ml/h. In each group, they have the possibility to add a PCEA bolus of 6ml every 20min as needed.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Dose of bupivacaine in milligrams per hour

    Total dose of bupivacaine in milligrams divided by the total duration of the epidural in hours

    Measured: 1 day

Secondary outcomes (11)
  1. Evaluation of pain

    Hourly pain measurement by visual analog scale, 0/10 being no pain and 10/10 being the worst pain imaginable

    Measured: 1 day

  2. Anesthesiologist manual bolus

    Total boluses by the anesthesiologist

    Measured: 1 day

  3. PCEA boluses received

    PCEA boluses received

    Measured: 1 day

  4. PCEA boluses requested

    PCEA boluses requested

    Measured: 1 day

  5. Time lapse before the first PCEA request after the epidural connection

    Time lapse before the first PCEA request after the epidural connection

    Measured: 1 day

  6. First stage

    Duration of the first stage of labour

    Measured: 1 day

  7. Second stage

    Duration of the second stage of labour

    Measured: 1 day

  8. Assisted vaginal delivery

    Number of assisted vaginal delivery (vacuum, forceps)

    Measured: 1 day

  9. Cesarean section

    Number of unplanned cesarean section

    Measured: 1 day

  10. Motor blockade

    Number of patients with a Bromage score ≥1

    Measured: 1 day

  11. Patient satisfaction

    Satisfaction of the analgesia provided by the epidural on a visual analog scale of 0-100, 0/100 being no satisfaction at all and 100/100 being entirely satisfied

    Measured: 1 day

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03730753, which also lists 19 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
