COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted 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

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients will receive propofol-only anaesthesia using the intermittent bolus technique.

Propofol will be administered through an intravenous cannula using the intermittent bolus technique (large loading bolus followed by small frequent boluses) which titrates dosage to adequate sedation.

The anaesthetist looking after the patient will give a propofol-only anaesthetic as per his or her usual procedure. The timing and dosage of boluses will not be stipulated by the researchers.

The loading dose is given immediately prior to commencing the endoscopy. Further boluses are given when deemed required by the anaesthetist.

Summary
Brief summary
The peak plasma propofol levels of endoscopy patients (Derived mathematically from the 3 measurements) along with the context sensitive half time of propofol (determined by the length of infusion) will allow the researchers to determine the time taken for plasma propofol levels to drop below levels known to cause driving impairment and thus estimate how long it takes for patients to drive safely after receiving a propofol only anaesthetic.
