Reusable (RU) flexible bronchoscopes (FB) require intermediate level disinfection operations to prevent transmission of infectious agents from patient to patient. These operations have a significant material and human cost and impact their availability in case of emergency. One alternative is the use of disposable FB.
The aim of the study is to evaluate the quality of FB during procedures carried out with each of the two solutions in intensive care unit (ICU), respiratory endoscopy (RE) and anesthesia (A) department.
A prospective non-interventional and non-randomized monocentric study compare the operator satisfaction of therapeutic procedures performed with RU FB (EB FujifilmTM range, FB/FI PentaxMedicalTM range, StorzTM intubation FB) versus disposable FB (aScope 3® and aScope 4® (AmbuTM), Broncoflex® (AxessvisionTM). An evaluation form is completed by the operator at the end of procedure. Judging criteria, rated from 0 to 10, concern handling, ergonomics, image and suction quality.

| Bronchoscopes overall reliability: comparison of physician satisfaction scores (rated on a scale from 0 to 10) between RU FB and disposable FB | A score is given per bronchoscopy (RU FB or disposable FB) All scores are aggregated as an average for FB RU and as an average for disposable FBs The 2 averages obtained are compared by a Student T- test after verification of the application conditions by a Fisher F-test (alpha = 5% threshold) Additional information about the measurement: 2/10: poor 4/10: mediocre 6/10: sufficient 8/10: suitable 10/10: excellent | Time required to carry out the bronchoscopy (between 5 and 15 minutes) |
