Inducing agent with maximum incidence of vomiting
Postoperative nausea and vomiting are more common following etomidate than following propofol or barbiturate induction. Propofol also possesses significant antiemetic activity with small (sub hypnotic) doses (i.e., 10 mg in adults). The median concentration of propofol with an antiemetic effect was 343 ng/mL, which also causes a mild sedative effect. This concentration can be achieved by an initial dose of propofol infusion of 10 to 20 mg followed by 10 ug/kg/minute.
