Assessment of Systemic and Cerebral Oxygen Saturation during Diagnostic Bronchoscopy: A Prospective, Randomized Study.

ABSTRACT:

Background

Arterial hypoxemia occurs in about 2.5-69% of cases during fiberoptic bronchoscopy and may necessitate administration of supplemental oxygen. Whether routine supplementary administration is indicated for all patients is a debated issue. In this prospective randomized study, we assessed the incidence of systemic desaturation (SpO₂ <90% or a >4% decrease lasting for more than 60 s) and wanted to find out whether cerebral desaturation occurs in parallel with systemic changes.

Patients and methods

92 consecutive patients scheduled for diagnostic bronchoscopy were randomly assigned to the no oxygen (O₂- group), 2 l/min supplemental O₂, or 4 l/min supplemental O₂ groups. Primary end points were systemic and cerebral des
