Objective To study the early micro-feeding in preterm children to promote the role of gastrointestinal function,increased gastrointestinal tolerance,early enough to meet the nutritional feeding.Methods of birth weight within 24 hours An introduction of different micro-feeding small doses,gradually increased and accompanied by milk and milk before the non-nutritive sucking.Results from the four target groups began to make the standard,statistically significant difference.Conclusion Early feedings can increase gastrointestinal motility in preterm children,the promotion of development and maturity of the gastrointestinal tract,and improve feeding tolerance, reducing the gastrointestinal tract in sufficient quantities to feed all the time,to reduce hospital stay.
