Abstract:
OBJECTIVES: Otitis media with effusion (OME) is rare among adults, but has been reported a higher incidence among intubated intensive care unit (ICU) patients. The purpose of this study is to examine the effect of the predisposing factors on OME.MATERIALS AND METHODS: An observational study has been performed to evaluate 100 intubated patients (>3days) in the ICU. We collected information about the age, sex, position, duration of orotracheal intubation, nasal nostril and diameter of nasogastric tube and level of consciousness. In addition, tympanometry and otoscopic examination were carried out for evidence of OME. RESULTS: We realized 535 ear observations. The results were classified as normal (type A and C1 Jerger tympanogram) or pathologic (type B and C2 Jerger tympanogram) curves. For statistical purposes we realized Cox regression adjusted by days from admission. Presence of nasogastric tube (≥18French), orotracheal intubation and unconsciousness were associated significantly with pathologic curves. CONCLUSIONS: Orotracheal intubation, nasogastric tube (≥18French), and unconsciousness were significant predisposing factors of OME.
