Increased Use of Noninvasive Ventilation Associated With Decreased Use of Invasive Devices in Children With Bronchiolitis

Abstract

To assess how a change in practice to more frequent use of high-flow nasal cannula for the treatment of bronchiolitis would affect the use of invasive devices in children.

Design: Retrospective cohort study of children under 2 years old admitted to the ICU with respiratory failure secondary to bronchiolitis. Outcomes and invasive device use were compared between two time periods, before and after the practice change.

Setting: Eighteen bed tertiary care PICU.

Patients: A total of 325 children: 146 from 2010 to 2012 and 179 from 2015 to 2016.

Interventions: None.

Measurements and main results: There were no significant differences between the two time periods regarding gender, race/ethnicity, medical history, and viral profile, although children were younger in the earlier cohort (median age of 1.9 mo [interquartile range, 1.2-3.5] vs 3.3 mo [1.7-8.6]; p < 0.001). There was an increased use of noninvasive ventilation in the second time period (94% from 69%; p < 0.001), as well as a decreased frequency of intubation (13% from 42%; p < 0.001) and reduced central venous catheter placement (7% from 37%; p < 0.001). There was no significant difference in mortality between the two groups. A logistic regression analysis was conducted, which found that time period, intubation, and hospital length of stay were all independently associated with central venous catheter placement.

Conclusions: A practice change toward managing patients with bronchiolitis in respiratory failure with less invasive means was associated with a reduction in the use of other invasive devices. In our cohort, minimizing the use of invasive ventilation and devices was not associated with an increase in mortality and could potentially have additional benefits.
