AbstractFebrile intensive care unit (ICU) patients were evaluated prospectively for sinusitis. Of 598 admissions, 26 patients with transnasal cannulas, ICU stays over 48 hours, and occult fevers were identified. These 26 underwent physical examinations and sinus computed tomographic (CT) scans. Maxillary centeses and cultures were done in patients with CT abnormalities. Patients with positive scans had nasal tubes removed and received decongestants. Scans were abnormal in 19 (73%). All patients with major CT changes had positive maxillary taps. Most infections were polymicrobial; enteric bacilli were common. Fever resolved with nonoperative care in 18 (95%) patients; in only 1 patient was fever primarily from sinusitis. Sinus CT scans are often abnormal in ICU patients with occult fevers and transnasal cannulas. Pneumatic otoscopy can serve as a screening tool. Most patients respond to nonoperative management. Remote infections are often present. Although radiographic nosocomial ICU sinusitis is common, it is seldom the sole source of fever or the proximate cause of significant morbidity.
