Brief summary

This research is designed to specifically compare the performance of the bronchoscopes in the clinical setting using a validated rating scale for bronchoscopic performance – the Global Rating Scale

Interventions

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
