Supine position
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
干预措施: 6 hours fasting and free oral intake of water (Behavioral)
30° semirecumbent position
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
干预措施: 6 hours fasting and free oral intake of water (Behavioral)
45° semirecumbent position
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
干预措施: 6 hours fasting and free oral intake of water (Behavioral)
