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.

Condition Intervention Phase
Inflammation Drug: propofol Drug: Intralipid 10% Drug: Saline Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Investigator, Outcomes Assessor)
Official Title: Propofol and/or Its Solvent Modify the Course of Inflammatory Response After Surgical Stress: A Randomized, Controlled, Double-blind Study
