About this study
Official title: Alternative to Intensive Management of the Active Phase of the Second Stage of Labor : a Multicenter Randomized Controlled Trial
Active phase of the second stage of labor corresponds to period of maternal expulsive efforts (i.e. pushing). An intensive management of this phase is usual in France. This study aims to evaluate the impact of an alternative "moderate" management during this pushing phase on neonatal and maternal issues and mode of delivery.
Read the detailed description
Management of the active phase of the second stage of labor is not an evidence-based practice. Management of this phase differs between countries. In France, national guidelines recommend to limit maternal expulsive efforts to 30 minutes (grade C). Thus, physicians (midwives and obstetricians) encourage usually women to push 3 times per contractions and to push on every contraction in order to deliver into a 30 minutes timing.
This study aims to evaluate the impact of an alternative "moderate" management during this pushing phase on neonatal and maternal issues and mode of delivery. In the intervention group, i.e. "moderate" pushing, women are encouraged to push only 2 times per contractions, to respect contractions without pushing and there is no limit of pushing duration.
The hypothesis is that "moderate" management of the active phase of the second stage allows decreasing frequency of neonatal morbidity at birth, decreasing frequency of operative delivery and increasing maternal satisfaction.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
"Moderate" managementProcedure or surgery
After randomization, women allocated to the intervention group, i.e. "moderate" pushing, are encouraged to push only 2 times per contractions, to respect contractions without pushing and there is no limit of pushing duration.
"Intensive" managementProcedure or surgery
This group corresponds to usual obstetrical management of active second stage in France. In France, national guidelines recommend to limit maternal expulsive efforts to 30 minutes (grade C). Thus, physicians (midwives and obstetricians) encourage usually women to push 3 times per contractions and to push on every contraction in order to deliver into a 30 minutes timing.
| Study group | Role | What they receive |
|---|---|---|
| "Moderate" management | Experimental | Women are encouraged by physicians to push only 2 times per contractions, to respect contractions without pushing and there is no limit of pushing duration. Receives: Procedure: "Moderate" management |
| "Intensive" management | Active comparator | Usual obstetrical care in France Receives: Procedure: "Intensive" management |

Questions about this trial
What is this clinical trial studying?
A study testing "Moderate" management and "Intensive" management in people with Active Second Stage, run by Assistance Publique - Hôpitaux de Paris at 1 site in France.
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 8 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 5 Sep 2025. 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 France. 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?
Neonatal morbidity composite measure (time frame: at childbirth). 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 NCT03018860, which also lists 7 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 5 Sep 2025.
