Rigid Bronchoscopy Home A-Z Health Information Health Library A-Z Rigid Bronchoscopy Overview In rigid bronchoscopy, a long metal tube (rigid bronchoscope) is inserted into the patient’s windpipe and main airways. The rigid bronchoscope’s larger diameter allows the doctor to use more sophisticated surgical tools and techniques.Rigid bronchoscopy is performed under general anaesthesia (unconsciousness with assisted breathing), like a surgical procedure. It is imperative to undergo evaluation by the physician as well as the anaesthesiologist prior to the procedure; this allows the discussion of risks and benefits and correction of any reversible contraindication. After general anaesthesia is administered, the patient is intubated with the rigid bronchoscope and attached to the ventilator.
