We investigated potential risks for any kind of contamination of propofol and etomidate in this study. After noting their lots, 18 ampules of each drug were aseptically opened. Samples were incubated after different time intervals. Two different sorts of culture media were chosen for incubation; sheep blood agar and thioglycollate broth for aerobic and anaerobic microorganisms, respectively. Number of positive samples for propofol showed a marked increase as a function of time. Unlike propofol, no bacterial growth was observed in etomidate.
