Nasal Prongs: Risks, Injuries Incidence and Preventive Approaches Associated with Their Use in Newborns

PURPOSE: To assess the incidence of nasal injury in newborns submitted to non-invasive ventilation (NIV) via binasal prongs, to identify risks that come with using this interface, and to present actions for nasal injury prevention. PATIENTS AND METHODS: Observational and descriptive study performed in neonatal intensive care unit (NICU) of a public hospital in the south of Brazil. This research was divided into three stages. In the first one, nasal injury incidence was assessed in 148 newborns, using data collection from medical records. In the second stage, injury incidence, severity and a preliminary analysis of risks associated with the prescription of binasal prongs were analyzed in 33 newborns who required NIV. In the third stage. recommendations were presented to prevent nasal injury during NIV with short binasal prong. RESULTS: The incidence of nasal injury in the first stage was 37.16%, and 63.64% in the second one. As for severity, 68.42% of the injuries showed Stage I severity, and 31.58% Stage II. The main risks associated with the use of binasal prongs were inappropriate prong size, inappropriate prong model, interface reuse, prolonged NIV use exclusively with binasal prongs, incorrect prong position and NIV circuit pulled. A total of 17 preventive approaches were recommended: 13 related to newborns care and not dependent on prior investment. Among them: to choose appropriate prong size; to keep the prong and the NIV circuit well positioned and periodically massages with circular movements in the nasal septum and columella. CONCLUSION: The inappropriate prong size, interface reuse, prong model, prolonged NIV use with binasal prong and incorrect prong and NIV circuit position may be associated with the high occurrence of injury in the NICU studied. Simple approaches concerning clinical staff care actions towards the newborn in NIV, which do not require a financial investment, can prevent nasal injury.
