AbstractPropofol is frequently associated with pain on injection. Previous studies have suggested that chilling of the propofol decreases pain significantly. This prospective, randomised, double-blind trial was designed to assess the effectiveness of cold propofol compared with propofol premixed with lignocaine in minimising pain on injection. Patients were allocated to one of four groups: propofol + lignocaine 0.1 mg.kg-1, propofol + lignocaine 0.2 mg.kg-1, cold propofol and a control group consisting of propofol premixed with normal saline and maintained at room temperature. The results of this study show that cold propofol is associated with a very high incidence of injection pain while lignocaine 0.1 mg.kg-1 premixed with propofol significantly decreases the incidence of pain (p < 0.001). Increasing the dosage of lignocaine above 0.1 mg.kg-1, however, does not significantly decrease the incidence of pain further. The addition of lignocaine also significantly decreases the incidence of excitatory side-effects.
