Bronchial fibrescopy in intensive therapy patients raises the problem of oxygenation during the procedure. The Fibroxy mask allows fibrescopy with simultaneous O2 administration and manual or mechanical ventilation. This study, which included ten patients, assessed the benefits of this device. During fibrescopy, the heart rate, the mean arterial blood pressure, and the arterial oxygen saturation (SpO2) remained unchanged and only one short episode of desaturation occurred. The satisfaction index was high. However, this mask did not fit closely to the patient's face, and an additional assistant was required for efficient ventilation. Moreover, end-tidal CO2 could not be monitored satisfactorily. After some improvements, this device seems to be of value for bronchial fibrescopy in intensive therapy unit.

Objectives: To assess the feasibility and safety of a new technique of fiberoptic bronchoscopy (FOB) tracheal intubation (TI) with noninvasive ventilation (NIV) via an endoscopic full facial mask with two openings, in case of acute respiratory failure (ARF) temporally improved by NIV, but requiring a mechanical ventilation.
Study Design: Clinical, prospective, open, noncomparative trial of feasibility with direct individual profit.
Patients: Sixteen patients with ARF (age: 60 +/- 17 years, PaO2 = 59 +/- 16 mmHg, PaCO2 = 64 +/- 26 mmHg, PaO2/FIO2 = 142 +/- 70 before NIV) (m +/- SD), requiring TI.
