Outcomes
Primary outcome [1] 268959 0
Time taken for driving ability to return to level deemed to cause impairment less than BAC 0.05.

Studies have been completed to determine the levels of propofol that cause psychomotor impairment to the same extent as a blood alcohol concentration (BAC) of 0.05 (Grant et al 2000). The researchers are also currently carrying out a preliminary study to determine the driving ability of subjects at varying levels of propofol. This data will be compared to data (from the same simulator) already available on driving impairment at a blood alcohol concentration of 0.05.
This comparison will give the researchers a level at which driving impairment is equal or less than that of subjects with a BAC of 0.05.

Driving ability is assessed using CyberCAR Lite driving simulator.
Timepoint [1] 268959 0
0.5, 1, 2, 3 hours post cessation of anaesthesia
Secondary outcome [1] 276694 0
Effect of length of procedure and dose of propofol on rate of recovery of driving ability.

Driving ability is assessed using CyberCAR Lite driving simulator.

Summary
Brief summary
Propofol is the trade name of the most commonly used intravenous general anaesthetic medication in Australia. This project will measure the level of impairment of driving skills after the administration of intravenous Propofol to a patient as part of an anaesthetic for gastrointestinal endoscopic procedures.
Following informed consent, the patient’s ability to drive on a video-game style driving simulator will be measured immediately prior to their surgical procedure prior to any medications being administered. This will constitute the patient’s baseline driving skill level.
The patient will then undergo their preplaned endoscopy procedure with propofol-only sedation. During the procedure, an extra cannula will be inserted in the opposite arm of the patient.
After anaesthesia has been ceased, the patient's driving skill will be re-measured on the same simulator at regular intervals (30 minutes, 1 hour, 2 hours, 3 hours post cessation of anaesthesia). each simualtion will take approximately 10 minutes.
Before each simulation, a blood sample will be taken from patients to determine the blood propofol concentration of the subjects.
