Abstract:
Parenteral nutritional support are used widely in clinical practice.Little is known about the effects of macronutrients on gastrointestinal motility and secretion.Several studies have provided evidence that nutrients during the circulatory phase of digestion influence gastrointestinal motility and secretion.Glucose exerts an inhibitory effect on gastrointestinal motility and secretion.The inhibitory effect of glucose is dose-dependent.Circulating amino acids at high concentrations stimulate gastric acid secretion,pancreatic enzyme secretion,gallbladder contraction and intestinal motility.Intravenous infusion of fat emulsions delays gastric emptying and interrupts the interdigestive intestinal motor pattern.
