Estado comportamental e sucção de recém-nascidos pré-termo tardios submetidos a fototerapia

Abstract

ABSTRACT Purpose To evaluate the behavioral state of late preterm newborns undergoing phototherapy and its association with non-nutritive sucking. Methods Cross-sectional study, carried out in a public teaching maternity hospital, a reference in high-risk pregnancy and part of the Baby-Friendly Hospital Initiative. Convenience sample, consisting of 60 late preterm newborns, cared for in rooming-in, divided into two groups. One group consisted of 30 newborns under phototherapy (case group) and another group with 30 newborns who were not under phototherapy (control group). Sample characterization data were obtained through anamnesis and collection from medical/hospital records. The assessment of behavioral status and non-nutritive sucking was carried out using the Preterm Oral Feeding Readiness Assessment Scale. Analyzes were performed using Jamovi (version 2.4.1). A significance level of 5% was adopted for all analyses. Results There was a significant difference in that the newborns in the case group had lower scores for behavioral organization and non-nutritive sucking. There was also a significant association between behavioral status and non-nutritive sucking in both groups. Conclusion It was concluded that late preterm newborns undergoing phototherapy had lower scores in the state of behavioral organization and non-nutritive sucking responses when compared to late preterm newborns who were not undergoing treatment. An association was observed between non-nutritive sucking responses and the state of behavioral organization in both groups.
