In a prospective, randomized study of 16 volunteers, a new galenic formulation of the induction hypnotic etomidate in lipid emulsion was compared with the commercial form in propylene glycol (Hypnomidate). After 0.3 mg/kg etomidate plasma levels (HPLC) and hypnotic effects (visual EEG analysis) of both formulations were almost identical. Onset of action occurred after 41.6 s in the propylene glycol group (group I) and 35.6 s in the lipid emulsion group (group II). The hypnotic effect (greater than or equal to D0) lasted 7 min 20 s in group I and 6 min in group II. Plasma levels in group I decreased from 630 ng/ml after 2 min to 170 after 8 min and 37 after 130 min. With group II the plasma levels decreased from 770 ng/ml after 2 min to 150 after 8 min and 42 after 130 min (Fig. 1). In the propylene glycol experiment, 4 of 8 volunteers reported pain on injection. Within 7 days 4 persons developed phlebitis or thrombophlebitis. O...
