Abstract: Objective: Based on the Delphi method, an integrated oral motor interventions was constructed by combining Hwang's 5 min oral motor interventions and Boiron's 2 min oral support, and to explore the effects of intervention on oral feeding ability, growth and development of preterm infants. Methods: A total of 28 experts were invited to conduct two rounds of Delphi expert consultation to construct the integrated oral motor intervention. The 144 included preterm infants were randomly divided into integrated oral motor interventions group (IOMIs group), oral motor interventions group (OMIs group) and the control group, and there were 48 cases for each group. The cases in the control group were with the routine developmental supportive care, the cases in IOMIs group were with the integrated oral motor interventions, and the cases in OMIs group were with Fucile oral motor interventions on the base of routine nursing care. The Preterm Infant Oral Feeding Readiness Assessment Scale was used to evaluate the oral feeding ability of preterm infants in three groups, the initial time of oral feeding was recorded, and the body weight was monitored every day. Results: The score of oral feeding ability at the 7th day and the 10th day after admission for the cases in the IOMIs group was higher than the score of those in the control group (P<0.05), there were more infants with oral feeding in the IOMIs group compared with the control group (P<0.05). The weight gain rate of cases in IOMIs group at the 16th day was higher than that of OMIs group and control group (P<0.05). Conclusion: The integrated oral motor interventions could not only save time, but also improve the oral feeding ability, promote the growth and development of preterm infants, and it is worthy of clinical application.
