The Effect of Mixing Lidocaine with Propofol on the Dose of Propofol Required for Induction of Anesthesia

Abstract

Adding lidocaine to propofol destabilizes the propofol emulsion. A randomized double-blinded trial found no statistically significant difference in the doses of propofol required for the induction of anesthesia whether administered as a freshly prepared propofol 1%/lidocaine 1% 10:1 mixture or as a separate injection after a dose of lidocaine.
