insufficient recruitment: 142 patients instead of 2,220 planned

The principal objective of the trial is to demonstrate that acupuncture could reduce the caesarean section rate for cervical dystocia.

Secondary objectives:

• reduce morbidity, fetal mortality and duration of childbirth;
• reduce the cost of care, due to diminution of caesarean sections and duration of obstetric labor;
• to evaluate the tolerance.

In this trial, pregnant women with at least 37 weeks of amenorrhea will be randomized to traditional chinese acupuncture, sham acupuncture, or usual care only.

9 investigator sites will participate to this trial targeting to enrol 2220 patients in total. 1780 subjects will receive acupuncture treatment, either effective treatment or sham, whereas 400 patients will receive usual care only.

Acupuncture therapy consists in stimulations on specific skin points of the abdominal area, which are specific acupuncture points in traditional chinese medicine for the induction of obstetric labor, according to the professional recommendations of the French Acupuncture and Traditional Chinese Medicine College.

Each patient will have a 5-week follow-up in this trial.
