[Does the lipid emulsion of Diprivan explain some pharmacological effects?].
In currently available experimental or clinical studies, there is no report of any adverse effect related to the lipid emulsion of propofol, for procedures not exceeding on average four hours of duration. General anaesthesia produced by propofol alone is associated with only moderate alterations of blood lipid concentrations. Therefore there is no restriction to the use of propofol. In the absence of precise data, it is recommended not to use propofol infusion in congenital hyperlipaemias (e.g., hyperchylomicronaemia). The lipid emulsion of propofol may alter the rheological properties of circulating blood, platelet aggregation, chemotactic activity of neutrophils and lymphocytes functions. These alterations are always limited. Furthermore, most studies which have recorded these effects are not directly applicable to clinical practice and additional studies are necessary. There are no data demonstrating that propofol would increase surgical bleeding or the incidence of postoperative infections. Since there is a low probability of these adverse effects, they should not limit the use of propofol.
