Abstrakt: Objective: The aim of this prospective study was to evaluate the value of sinus echography results to directly indicate a transnasal puncture in intubated patients with suspicion of nosocomial maxillary sinusitis.Design: prospective clinical investigation.Setting: medical intensive care unit.Patients: sixty patients undergoing intubation and mechanical ventilation more than 2 days, with a clinical suspicion of maxillary sinusitis with purulent nasal discharge.Interventions: 120 sinuses were examined by sinus ultrasound. The image defined as normal was an acoustic shadow arising from the front wall. Two levels of positive echography were described: (1) a partial sinusogram was defined as the visualization of the hyperechogenic posterior wall of the sinus; and (2) a complete sinusogram was defined as the hyperechogenic visualization of posterior wall and the extension by the internal and external walls of the sinus. When sinus ultrasound was positive, a transnasal puncture was performed the same day. The transnasal puncture was positive if a fluid was obtained from sinus aspiration. The transnasal puncture was negative if there was no aspirated material.Measurements and Results: sinus ultrasound was positive in 84 cases (54 complete sinusograms and 30 partial sinusograms). Seventy-eight of 84 transnasal punctures were positive. Sensitivity of a sinusogram for obtaining positive transnasal puncture was 100%, and specificity was 86% (100% in case of complete sinusogram) in a clinically selected population. The only six negative transnasal punctures were performed in patients with partial sinusogram.Conclusions: Ultrasound sinusitis evidence seems to be of value to indicate and perform a transnasal puncture directly, avoiding CT exam.
