Development-off Motility

摘要

Advances in neonatology over the past 2 decades have resulted in the survival of very preterm infants. However, the major limiting factor to survival of such infants is the ability to initiate and maintain adequate nutrition.Multiple maturational events are necessary for successful enteral nutrition of the infant: coordination of sucking and swallowing; effective gastric emptying; forward propagation of small intestinal contents, and finally, colonic elimination. Since normal gastrointestinal function relies on the integrated maturation of absorptive, secretory and motor function, a delay in any one of these processes will result in disturbed gastrointestinal function. Immature gastrointestinal motility manifested by vomiting, abdominal distention, delay in stooling and constipation commonly postpone the time of full enteral feeding in premature infants.
