Propofol was administered intravenously using the Diprifusor system, which is a target-controlled infusion system of proposal, through an intravenous catheter place in the patient' forearm. The proposal infusion started with an initial effect-site concentration or 4 micro g/mL for 3 min and increased in increments of 0.5 micro g/mL every 30 sec after the first 3 min until the patient lost their consciousness. Th predicted blood concentration and the predicted effect-site concentration of propofol required for loss of consciousness were recorded.
