    qualitative ultrasound assessment of gastric contents

    through study completion, an average of 20 min

Study Arms (4)

Supine position

SHAM COMPARATOR

patient in supine position, lying on the back, turned in the right lateral decubitus and turned in the left lateral decubitus in a randomized way, after prolonged fasting and 10 min after free oral intake of water

Behavioral: 6 hours fasting and free oral intake of water

30° semirecumbent position

SHAM COMPARATOR

patient in semirecumbent position (head of the bed elevated to 30°), lying on the back, turned in the right lateral decubitus and turned in the left lateral decubitus in a randomized way, after prolonged fasting and 10 min after free oral intake of water

Behavioral: 6 hours fasting and free oral intake of water

45° semirecumbent position

SHAM COMPARATOR

patient in semirecumbent position (head of the bed elevated to 45°), lying on the back, turned in the right lateral decubitus and turned in the left lateral decubitus in a randomized way, after prolonged fasting and 10 min after free oral intake of water

Behavioral: 6 hours fasting and free oral intake of water

90° semirecumbent position

SHAM COMPARATOR

patient in semirecumbent position (head of the bed elevated to 90°), lying on the back, after prolonged fasting and 10 min after free oral intake of water

Behavioral: 6 hours fasting and free oral intake of water

Interventions

Ultrasound examination of the gastric antrum are performed in volunteers after prolonged fasting and 10 min after oral intake of water. Volunteer should be lying on his/her back, right lateral decubitus position and left lateral decubitus position with randomization of the order.
