COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted/resubmitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Arm 1 – fibreoptic guided orotracheal intubation in anaesthetised patient with Ambu Ascope
- intervention post induction of anaesthesia
- intervention to be performed until endotracheal tube in place or until operator decides to stop
- intervention to be performed once only on the participant
- each participant to receive only one intervention - either Ambu Ascope or Karl Storz intubating bronchoscope
- intervention will only take place during a single episode of anaesthesia - average duration will be 3 minutes
