Effect of Olfactory and Gustatory Stimulation of Breast Milk Combined with Non-nutritive Sucking on Feeding Tolerance and Development in Premature Infants
Objective:To investigate the effects of olfactory and gustatory stimulation of breast milk combined with non-nutritive sucking in premature infants.Method:A total of 86 premature infants admitted to the First Hospital of Putian City from September 2021 to September 2023 were selected as the study objects and divided into two groups according to random number table method,with 43 cases in each group.The control group received routine intervention,and the observation group received olfactory and gustatory stimulation of breast milk combined with non-nutritive sucking intervention.The indexes related to rehabilitation,feeding tolerance,sucking ability and development of the two groups were compared.Result:The amount of residual milk per time in the observation group was lower than that in the control group,the number of daily defecation times was higher than that in the control group,and the time of meconium depletion,whole intestinal feeding time,gastric tube removal time,feeding transition time and birth weight time were shorter than those in the control group,the differences were statistically significant(P<0.05).The total incidence of feeding intolerance in the observation group was 4.65%,which was lower than 18.60%in the control group,and the difference was statistically significant(P<0.05).After the intervention,the feeding efficiency and sucking rate of the observation group were higher than those of the control group,and the differences were statistically significant(P<0.05).The weight growth,head circumference growth and length growth of 14 d after birth of the observation group were higher than those of the control group,the differences were statistically significant(P<0.05).Conclusion:Olfactory and gustatory stimulation of breast milk combined with non-nutritive sucking can shorten the oral feeding time of premature infants,improve sucking ability,reduce feeding intolerance,and promote physical development.
