Fig. 1. Plasma bradykinin concentrations when long chain triglyceride emulsion propofol (LCT propofol) and microemulsion propofol and their components were mixed with human blood. MIX = mixture of other ingredients in microemulsion propofol minus propofol, PP188, and PEG660HS; PEG660HS = 0.7% polyethylene glycol 660 hydroxystearate; PP188 = 10% purified poloxamer 188.
