The inflammatory properties of propofol are still under debate. Apolipoprotein A-I (Apo A-I)
is involved in the inflammatory process. This study was designed to determine whether and how
propofol or its solvent modulate Apo A-I and the inflammatory response after surgical stress.
The investigators study hypothesis was that propofol might modify the Apo A-I blood levels,
and thus, modulate the postoperative inflammatory course.
