Abstract

Croup is a common respiratory illness in children with a substantial variation in the severity of symptoms. Most of the patients present with mild symptoms, but patients with severe croup require intensive care unit (ICU) management. The aim of this study was to investigate the airway management of patients with severe croup who required intubation and determine the risk factors for prolonged intubation. We performed an 18-year retrospective observational cohort study at the pediatric ICU of a tertiary children's hospital in Japan. A total of 16 patients with croup who were intubated for upper airway obstruction were included in the study. Most patients (13of 16, 81%) were intubated with an endotracheal tube (ETT) smaller than their age-appropriate size. The median difference in the internal diameter (ID) between the selected ETT and the age-appropriate size was 1.0 mm (interquartile range: 0.5–1.0). Multivariate analysis performed on factors affecting the cumulative incidence of extubation revealed that the difference in ID between the selected ETT and age-appropriate size (mm) significantly reduced the duration of intubation (hazard ratio: 0.092, p = 0.03). A downsized ETT without a cuff may be recommended for intubation of patients with croup.
