Sequential Posture Change Fastens Gastric Emptying of Large Volume Bolus Intake of Normal Saline: A Pilot Study
The physiology of gastric emptying (GE) is complex and incompletely understood due to the interplay of several factors such as age, sex, volume, pH, temperature, osmolality, ion and energy content, gravity, posture, physical activity, and food consistency [1, 2, 3, 4, 5, 6]. It is well known that posture and gravity affect GE mainly via changes in gastric configuration, which changes the intra-gastric distribution and ultimately the pressure gradient (pressure pump mechanism of GE) across the gastroduodenal segment . Postural changes are also associated with changes in gastric motility (peristaltic pump mechanism of GE) and intra-gastric distribution of liquid meals [7, 8].
