Randomized Controlled Trial Comparative Study Clinical Trial
Pain on injection of propofol. Methods of alleviation.
A controlled randomised double-blind design was used to study the effect of lignocaine on the pain produced by intravenous injection of propofol. Patients received a 2-ml pretreatment solution with temporary venous occlusion, followed by an induction solution. ⋯ There were no significant differences in the incidence of pain among the groups which received lignocaine as pretreatment and the groups which received lignocaine mixed with propofol. Sixty-eight percent of patients who experienced pain or discomfort recalled it in the postoperative period.

Randomized Controlled Trial Comparative Study Clinical Trial
Pain on injection of propofol: the effect of injectate temperature.
A double-blind, randomised clinical study was undertaken to compare the effect of temperature on the incidence and severity of the pain experienced on injection of propofol. The number of patients who experienced pain and the severity of the pain were reduced significantly when propofol was administered at a temperature of 4 degrees C. The efficacy of propofol as an induction agent appeared to remain unaltered.
