Evaluation of the Single Use Flexible Optical Scope Versus Multiple Use Flexible Optical Scopes for Intubation

Evaluation and Comparison of the New Single Use Ambu aScope With Olympus BF 160 Multiple Use Scope for Securing the Airway of the Anaesthetised/Awake Patients' Normal or Difficult Airway

The study is in two parts

Part one of the study describes the use of the new single-use flexible video-scope for intubation of patients with predicted normal airways.

Part two compares the performance of the single-use flexible video-scope with that of a conventional flexible video-scope for awake intubation of patients with predicted difficult airways.

The hypothesis is that the new single-use flexible video-scope for intubation performs as well as the traditional scope.

Inclusion Criteria:

1. Study part 1:

   • Patients scheduled for tracheal intubation and predicted to have a normal airway

   • ASA class I, II or III
   • >18 years

Exclusion Criteria:

   • Massive bleeding from the mouth
   • Previously abandoned flexible optical intubation

2. Study part 2:

   • Massive bleeding from the mouth
   • Previously abandoned flexible optical intubation
