Comparative Study
Determinants of liquid gastric emptying: comparisons between milk and isocalorically adjusted clear fluids.
Although current preoperative fasting guidelines apply restrictions to drinks containing milk because of delayed gastric emptying, the safe volume of milk that can be consumed up to 2 h before surgery on a theoretical basis has not yet been defined. We aimed to determine whether delayed gastric emptying depended mainly on the total amount of calories irrespective of compositional differences between milk and clear fluids. ⋯ UMIN000012537.
