Transient evoked otoacoustic emissions in term and pre-term neonates in the presence and absence of suction

Abstract

Objective: to verify if the sounds caused by the suction / swallowing mechanism interfere with the TEOAE in the term and preterm newborns. Method: a study of 40 newborns (27 full-term and 13 preterm), evaluated with presence of TEOAE, at rest and in suction situation. Results: At the time of suctioning / deglutition, the frequency of suctioning / deglutition was analyzed by frequency; it was found that in 2000 Hz, a greater number of failures occurred during suction Conclusion: There was no statistically significant difference between the results obtained without suction and nutritive suction in the breast.
