About this study
Official title: Effect of Amnioinfusion on External Cephalic Version After Initial Failure a Prospective Multicentric Randomized Study
The aim of the study is to evaluate the effect of transabdominal amnioinfusion before second external cephalic version after initial failure.Patient with a single foetus, at term, in breech presentation and after a first cephalic version are included. The randomisation determines whether the patient is included in the group with amnioinfusion before second cephalic version or with usual second cephalic version only; The efficacy's evaluation is based on rate of cephalic presentation at birth.Success rate of cephalic version with or without transabdominal amnioinfusion, rates of cesarian section in the two groups,maternal and fetal morbidity, time between second cephalic version and birth will be studied.
Prospective interventional randomized sequential comparative multicentric study. A maximum of 240 patients will be included (120 in each group). As the study is sequential it will be over as soon as a significative difference is shown.
Read the detailed description
The purpose of the study is to evaluate the effect of transabdominal amnioinfusion before a second external cephalic version after initial failure. In case of success it could be an alternative to cesarian section. Without any other technique the foetus is in cephalic presentation after a first external cephalic version in 50%.
Patients with a single fetus, at term, in breech presentation are proposed to participate. The randomization is done at the inclusion and determines whether the patient is included in the group with amnioinfusion before second cephalic version or usual second cephalic version only. The only difference between the two groups is the realisation of an amnioinfusion, the cephalic version's technique is the same.
Efficacy's evaluation is based on rate of cephalic presentation at birth. Success rate of cephalic version, rates of cesarian section, maternal and fetal morbidity in the two groups, time between second cephalic version and birth will be studied.

Questions about this trial
What is this clinical trial studying?
A study testing transabdominal amnioinfusion in people with Breech Presentation, run by University Hospital, Tours at 2 sites 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 5 inclusion and 6 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: stopped early, as of the sponsor's last update on 30 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites 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 was stopped early. Results are not available in the source record.
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?
cephalic presentation at birth (time frame: at birth). 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 NCT00465712, which also lists 42 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 30 Dec 2025.
