A randomized study assessing the systematic search for maxillary sinusitis in nasotracheally mechanically ventilated patients. Influence of nosocomial maxillary sinusitis on the occurrence of ventilator-associated pneumonia.

The objective of this randomized study was to compare the occurrence of nosocomial pneumonia in nasotracheally intubated patients who were randomly allocated either to a systematic search of sinusitis by CT scan (study group) or not (control group). A total of 399 patients were included: 272 male and 127 female; mean age, 61 ± 17 yr; SAPS: 12.6 ± 4.9. The study group consisted of 199 patients and the control group consisted of 200. In the study group, sinus CT scans were performed in case of fever at Days 4 and 8 and then every 7 d. Nosocomial sinusitis was defined as follows: fever of ⩾ 38 ° C, radiographic (sinusal air-fluid level or opacification on CT scan) signs, and presence of purulent aspirate from the involved sinus puncture with ⩾ 103 cfu/ml. Patients with sinusitis received sinus lavage and intravenously administered antibiotics. In the study group, 80 patients experienced nosocomial sinusitis. In the control group, no patient was treated for a sinusitis. Ventilator-associated bronchopneumonia ...
