Abstract
OBJECTIVES: The objective of this study is to describe swallow:breath interaction (SwBr) and phase of respiration incident to swallow (POR) during non-nutritive suck in infants with bronchopulmonary dysplasia and determine if speech-language intervention can modify the characteristics of non-nutritive suck in these infants. METHODS: Logistic regression models were used to describe SwBr and POR in 16 low-risk preterm (LRP) infants and 43 infants with bronchopulmonary dysplasia. Infants with bronchopulmonary dysplasia were randomized to receive individualized intervention from a speech-language pathologist (BPDwithTX) or standard care (BPDnoTX). RESULTS: No significant differences were noted between low-risk infants and either group of BPD infants for the distribution of SwBr types. Infants with bronchopulmonary dysplasia showed minor differences in the progression of POR. Speech-Language intervention did not change the progression of SwBr or POR in infants with bronchopulmonary dysplasia. CONCLUSION: Infants with bronchopulmonary dysplasia can improve the progression of SwBr through practice as effectively as low-risk preterm infants can. The minor differences in POR in infants with bronchopulmonary dysplasia are consistent with dysmature development as seen with other feeding studies of infants with this disease. Speech-Language intervention did not modify the developmental progression of swallow:breath interaction or phase of respiration incident to swallow.
