Fig. 3. Thiobarbituric acid reacting substances (TBARS) in sulfite propofol emulsion during a simulated 12-h intravenous drip at room temperature. Two vials (A and B ) of sulfite propofol emulsion (both 08/03, 010K310) were dripped over a period of 12 h and emulsion collected and analyzed as described in Methods. Values are the means (± SD) of triplicate determinations. *Values significantly different than 0-h values.
