Laryngotracheobronchitis as a complication of measles during an urban epidemic.

Abstract

To evaluate demographic and clinical correlates of laryngotracheobronchitis (LTB) as a complication of measles during a community-wide epidemic. Retrospective review of medical records. Childrens Hospital Los Angeles, a large urban pediatric facility, during a regional epidemic of measles studied January through June 1990. All patients identified at our hospital who met Centers for Disease Control criteria for measles. Of 440 patients with measles, 82 also had LTB (18.6%). Patients in whom LTB developed were significantly younger (mean +/- SD: 14.7 +/- 8.2 months) than the cohort (24.8 +/- 30.1 months) (p less than 0.001) and more likely to require hospitalization (91.5%) than the cohort (44.3%) (p less than 0.001). Thirteen patients (17.3%) required intensive care, including 9 (11%) who required endotracheal intubation for a mean of 8.3 +/- 7.1 days. Pulmonary function testing of five patients with an endotracheal tube in place, including three not clinically assessed as having pneumonia, indicated the presence of concomitant lower respiratory tract disease. Laryngotracheobronchitis was a frequent and often severe complication of measles. The likelihood that LTB would develop was inversely related to age, generally required inpatient care, and necessitated endotracheal intubation in severely affected patients.
