Intubated or tracheostomised patients on ACCU do not necessarily need to be fasted prior to going to the operating theatre. In essence, for intubated patients, only those having surgery involving the airway or abdomen need to be formally fasted.
The policy can be found in Box.
This also forms an appendix to the Trust Nil by Mouth policy. To avoid confusion with the anaesthetist, please consider calling them to discuss the reasoning behind your decision.
