tube feeding and parenteral or IV feeding.

is not possible enteral nutrition has more
在生理上比肠胃外营养更具有优势
physiological benefits compared to parenteral nutrition
这优势包括保持小肠绒毛
including the maintenance of the heightened activity of
及小肠刷状缘酶活性的提高
intestinal villi and brush border enzymes,
能更好地保护
better preservation of specific gut nutrients such as
小肠营养内特殊物质
glutamine and short chain fatty acids and an upholding

of the mucosal membrane surrounding the intestine.
