Objective
Intubation is a risk factor for nosocomial sinusitis in adult intensive care patients. Sinusitis in intubated adults can be an occult cause of fever. In children nasal intubation may be associated with a greater risk of sinusitis. No pediatric study has determined the incidence of nosocomial sinusitis in the pediatric intensive care unit (PICU) setting. We hypothesized that within a subset of patients who had head CT imaging: (1) the incidence of sinusitis in PICU patients exceeds the incidence in non-PICU patients; (2) the incidence of sinusitis is greater in PICU patients with a tube (nasotracheal, nasogastric, orotracheal, or orogastric); and (3) nasal tubes confer an increased risk for sinusitis compared to oral tubes.
Design

Setting
Independent not-for-profit pediatric healthcare system
Patients
PICU and non-PICU (inpatients hospitalized on medical-surgical wards) patients referred for head CT
Interventions
None
Measurements and Main Results
CT images were evaluated for the presence of a tube and sinusitis. Images were scored using the Lund-MacKay (LM) staging system. Sinusitis was defined as a LM score >3.5. 596 patients were studied; 395 (66.3%) PICU. 197 (50%) PICU versus 69 (34.3%) non-PICU patients had sinusitis (p <0.001). 108/147 (73.5%) PICU patients with a tube present had sinusitis versus 88/248 (35.9%) of those without a tube present (p <0.001). There was no significant difference in sinusitis based on tube location (p=0.218). Younger age or the presence of a tube increased the probability of sinusitis (p <0.001).
Conclusions
Almost 50% of our PICU patients imaged for reasons other than evaluation for sinus disease had evidence of sinusitis. This finding raises the concern that sinusitis in PICU patients is common and likely should be considered in the differential diagnosis of fever in PICU patients.
