Abstract

OTA, Nathalie Tiemi; DAVIDSON, Josy  and  GUINSBURG, Ruth. Early nasal injury resulting from the use of nasal prongs in preterm infants with very low birth weight: a pilot study. Rev. bras. ter. intensiva [online]. 2013, vol.25, n.3, pp.245-250. ISSN 0103-507X.  https://doi.org/10.5935/0103-507X.20130042.

OBJECTIVE:

To analyze the incidence of early-onset nasal injury in infants with very low birth weight and indication for noninvasive ventilation via nasal prongs.

METHODS:

A prospective case series of infants with gestational age <37 weeks, weight <1.500 g and postnatal age <29 days. The patients were evaluated three times daily from the installation of nasal prongs to the 3rd day of use. The patients' clinical conditions and the device's characteristics and its application were analyzed. The initial analysis was descriptive, indicating the prevalence of nasal injury and factors associated with it. Categorical data were analyzed using the chi-squared test or Fisher's exact test, and numerical data were analyzed using the t-test or the Mann-Whitney test.

RESULTS:

Eighteen infants were included; 12 (with a gestational age of 29.8±3.1 weeks, birth weight of 1.070±194 g and a Score for Neonatal Acute Physiology - Perinatal Extension (SNAPPE) of 15.4±17.5) developed nasal injuries (injury group), and 6 (with a gestational age of 28.0±1.9 weeks, weight of 1.003±317 g and SNAPPE of 26.2±7.5) showed no nasal injury (uninjured group). The injury group subjects were more often male (75% versus 17%), and their injuries appeared after an average of 18 hours, predominantly during the night (75%).

CONCLUSION:

The incidence of nasal injury in preterm infants who experienced noninvasive ventilation via nasal prongs was high, and a study of associated factors may be planned based on this pilot.
