The use of cricoid pressure to prevent gastric aspiration or regurgitation in case of "full stomach" situation or emergency is still controversial in the adult population. Moreover this maneuver is no more recommended in children by some European pediatric anesthesia societies, because of a lack of evidence of its protective effect against gastric aspiration and its possible adverse effects.
A new approach to occlude effectively the esophageal lumen has been recently described in adults and has shown its effectiveness to prevent gastric insufflation. But this maneuver has so far not been evaluated in the pediatric population and could be an alternative to prevent gastro-esophageal regurgitation and pulmonary aspiration in children

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| children | Experimental | Compression of adjacent vessels (jugular vein and carotid artery), near the left paratracheal area. The risk of compression of the vessels will be assessed before performing the maneuver. At the screening time before the intervention, we will perfom an ultrasonography measurement while we applied the maneuver in order to eliminate a risk of compression of the vessels, defined as a reduction in diameter of 50%. |

| MAVEPPIC: MAsk VEntilation with Paratracheal Pressure In Children | Other | Pressure will be applied with two fingers in the area located between the trachea and the sternal head of the sternocleidomastoid muscle on the left side to compress the cervical esophagus. The force applied (after measuring the equivalent force applied on a precision scale) will be about 10 - 15 N. This force will be adapted according to the child's body weight : 10 N below 20 kgs and 15 N between 20 kgs and 40 kgs |
| Measure | Description | Time Frame |
|---|---|---|
| Presence of air artefacts during positive pressure ventilation as evaluated by simultaneous gastric ultrasonography | Presence of antral and/or gastric air artefact described in ultrasonography. US will be perform during positive pressure mask ventilation. | We will perfom a unique measurement of gastric air artefact by ultrasonography after 2 minutes of positive pressure ventilation. |
| Measure | Description | Time Frame |
|---|---|---|
| The verification of the actual position of the esophagus on the left side of the trachea at the place where LPPP will be applied (feasibility of LLPP) | Left side of the trachea ultrasonography performed before positive pressure ventilation | Before the beginning of positive pressure ventilation during 1 minute |
