Brief summary
Realization of a gastric ultrasound just before surgery, to measure the surface of antrum of stomach and compare if divergence sizes can be observed between women with a operative hysteroscopy and women with a planned caesarean section. To know if anaesthesia need to be adapted to the population.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Measure of antral surface | Just before anesthesia and surgery | Measure of gastric antrum surface by Ultrasound on operative hysteroscopy women and planned caesarean section women. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Measure of Perlas score | Before surgery | Perlas score (Grade 0, defined as an empty antrum in both the supine and the right lateral decubitus positions, indicates that the stomach is completely empty; grade 1, defined as visualisation of gastric fluid content in the right lateral position only, corresponds to low gastric fluid volume; grade 2, defined by visualisation of liquid contents in both supine and right lateral positions, suggests a high gastric fluid volume with increased risk for pulmonary aspiration) measure by Ultrasound on operative hysteroscopy women and planned caesarean section women. |
| Assessment of anxiety on gastric residue with a numeric scale | Before surgery | Measure of anxiety with a numeric scale (0 = no anxiety, 10 = maximal anxiety) |
| Assessment of frequency of intraoperative inhalation | During surgery | Comparison of proportion of inhalation between the two population |
| Incidence of fasting on gastric residue between the two populations | Before surgery | Comparison of antral surface with fasting as covariable |
