Shorten the Time Required to Correct the Arrival of Complete Oral Feeding in Premature Infants

Shorten the Time Required to Correct the Arrival of Complete Oral Feeding in Premature Infants Whose Corrected Gestational Age Are Less Than 32 Weeks

Non-nutritive sucking combined with a step-by-step oral feeding regimen shortens the total oral feeding cycle in premature infants

In order to improve the feeding of premature infants <32 weeks of gestation, a complete oral feeding intervention program is provided for premature infants, which combined the evaluation of oral feeding readiness, the evaluation of oral feeding performance, non-nutritional sucking intervention and progressive feeding program. Premature infants will be assessed 12 times a day before feedings using the Feeding Preparation Scale. Assess the premature infants by using the Feeding Preparation Scale. If the premature infant does not meet the oral feeding standard, let the premature infant use the non-nutritive sucking for 3 minutes before the nasal feeding; if the premature infant meets the oral feeding standard, use the non-nutritive sucking for 3 minutes, and refer to the feeding schedule for the premature infant. The whole intervention stops until the premature infant achieves the full oral feeding. Length of time required for complete oral feeding of premature infants is compared between the intervention group and the control group to evaluate the effect of the complete oral feeding intervention program on improving the feeding of premature infants <32 weeks of gestation.

Premature infants will be assessed 12 times a day before feedings using the Feeding Preparation Scale. Feeding of premature infants using different interventions based on the results of the Feeding Preparation Scale.

Pre-feeding assessments will be performed from premature infants corrected for gestational age at 34 weeks. If the baby's vital signs are stable, the method of oral feeding and then nasal feeding is used, and feeding 8 to 12 times a day until the baby reaches complete oral feeding. Routine nursing care is identical to the control group.

Premature infants will be assessed 12 times a day before feedings using the Feeding Preparation Scale by trained nurses. Assess the premature infants by using the Feeding Preparation Scale. If the premature infant does not meet the oral feeding standard, let the premature infant use the non-nutritive sucking for 3 minutes before the nasal feeding. If the premature infant meets the oral feeding standard, use the non-nutritive sucking for 3 minutes, and refer to the feeding schedule for the premature infant.

Pre-feeding assessments will be performed from premature infants corrected for gestational age at 34 weeks. If the baby's vital signs are stable, the method of oral feeding and then nasal feeding is used, and feeding 8 to 12 times a day until the baby reaches complete oral feeding.

Transition time was defined as the days needed from introduction of oral feeding to obtain autonomous oral feeding when the nasogastric tube was removed and all the daily milk volume was taken from the bottle. time of complete oral feeding
