Trial summary

Labor pain is complex to understand and challenging to define because of the interaction of multiple maternal and fetal factors. Poorly controlled acute post-procedural pain may result in harmful physiological and psychological consequences for both mother and baby. Read more about this study

About this study

Official title: A Prospective Observational Study to Evaluate Efficacy of Simple Questions to Predict Labor Pain and Epidural Analgesia Use in Parturients

Labor pain is complex to understand and challenging to define because of the interaction of multiple maternal and fetal factors. Poorly controlled acute post-procedural pain may result in harmful physiological and psychological consequences for both mother and baby. It is therefore important to understand the prelabor factors that may affect the labour pain to facilitate the intrapartum pain management. The goal of this prospective observational study is to verify if expectations regarding pain experience translate to actual pain outcomes for women who are undergoing induction of labor.

Read the detailed description

A prospective observational cohort study. 100 parturients having induction of labor that match inclusion criteria will be asked to participate. After written informed consent, vital signs and patient demographics will be obtained and recorded. A 3 question survey will be given. Patients will be asked to rate, using a 0-10 cm visual analog scale (VAS), their anxiety level ("On a scale of 0-10 cm, with 0 being not anxious at all through 10 being extremely anxious, how anxious are you about your upcoming labor and delivery?"), their anticipated pain ("On a scale of 0-10, with 0 being no pain at all and 10 being pain as bad as you can imagine, how much pain do you anticipate experiencing during your upcoming labor and delivery?"), and using a categorical scale, to rate their anticipated epidural analgesic need ("On a scale of 0-5, with 0 being none at all, 1 being much less than average, 2 being less than average, 3 being average, 4 being more than average, and 5 being much more than average, how much epidural pain medication do you anticipate needing during your upcoming labor and delivery?"). Then 24 hours after delivery, patient VAS scores will be recorded, number of boluses, total number of hours of labor, patient comfort level and satisfaction

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • SurveyOther

    Patients coming for induction of labor will be handed a survey regarding their expectation of their coming labor pain. And then will be followed up after 24 hours of their delivery.

What is being measured

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

  1. Area Under the Curve (AUC)

    this outcome will be measured at day 1 of delivery

    Measured: this outcome will measure the pain scores during labour from the start of epidural insertion until its discontinued.

Secondary outcomes (9)
  1. Time from onset of labor to epidural analgesia

    Measured: minutes > 30 minutes

  2. Cervical dilatation at the time of request(cm)

    Measured: hours (>1 hour)

  3. Pain score at the time of request of labor analgesia

    Measured: VAS (1-10)

  4. Duration labor

    Measured: hours (> 1 hour)

  5. Number of epidural boluses

    Measured: hours (> 1 hour)

  6. Patient comfort during labor (1-5)

    Measured: hours (>1 hour)

  7. Pain VAS during Epidural insertion (0-10)

    Measured: hours (> 1 hour)

  8. Patient satisfaction with epidural analgesia

    Measured: hours ( >1 hour)

  9. Mode of delivery

    Measured: hours (>1 hour)

Questions about this trial

What is this clinical trial studying?

An observational study of Labor Pain, run by London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's at 1 site in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Area Under the Curve (AUC) (time frame: this outcome will measure the pain scores during labour from the start of epidural insertion until its discontinued.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02824302, which also lists 3 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Dec 2018; AzTrials last refreshed its copy on 7 Nov 2026.
