OBJECTIVE: To investigate the protective effect of a hydrocolloid nasal dressing on the incidence and severity of nasal injury and continuous positive airway pressure (CPAP) failure in preterm infants receiving nasal CPAP (N-CPAP).


METHODS: A randomized controlled trial was conducted over 4 months in 2019 at level 3 neonatal ICUs in two hospitals affiliated with Isfahan University of Medical Sciences, Iran. Eighty eligible infants were born at 32 weeks of gestation or younger and/or with a birth weight of 1,500 g or less and had received between 4 and 72 hours of CPAP. Infants were randomly assigned to two groups; the intervention group used a protective dressing, and the control group received routine care. Data collection tools included a demographic questionnaire and nasal injury assessment score chart.


MAIN OUTCOME MEASURES: The incidence and severity of nasal injury in preterm infants undergoing N-CPAP.


RESULTS: Infants in the intervention group had a significantly lower incidence and severity of nasal injury compared with the control group: 15 of 40 (37.5%) versus 37 of 40 (92.5%; P < .001). Overall, the injuries identified in this study were mostly mild and moderate, with only three severe injuries in the intervention group and five in the control group. No significant differences were detected in CPAP failure (P > .05).


CONCLUSIONS: The studied nasal barrier dressing is a safe and convenient solution to reduce nasal injury in preterm infants receiving N-CPAP.
