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.
Timepoint [1] 276694 0
0.5, 1, 2, 3 hours post cessation of anaesthesia
