Brief summary
The practice of ultrasounds increases in delivery rooms every year. Indeed, this method can help to visualize elements that may not be observable after clinical examination. Moreover, it is known that a fetal head engagement can lead to an instrumental extraction and in case of error, which happens in some cases, fetal and maternal risks are possible. These elements led to the investigators' hypothesis which is that a trans-perineal ultrasonography may facilitate the evaluation of a clinical fetal head engagement in case of doubt.
Detailed description
It's a monocentric, transversal, clinical trial regarding women giving birth at the GHICL's hospital Saint Vincent de Paul. Clinical examinations will be done by the midwives following the indications given on the clinical form. A trans-perineal echography will then be done by technical operators following the ultrasonography form. These examinations will only last a few minutes, no further tests will be done afterwards.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Perineal-cephalic distance measured in milimeters | one day | Determine the perineal-cephalic distance via echographic examination, which gives a better sensitivity/specificity in comparison to the clinical examination considered as a gold standard |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Perineal-cephalic distance measured in milimeters according to specific conditions: posterior positions, th etime from induction to delivery, presence of caput succedaneum | one day | Determine the interest of the echography measurement in specific conditions (variety of posterior presentations, caput succedaneum, work stagnation) regarding the diagnosis of engagement, in case of doubt concerning the clinical examination |
