Randomized Controlled Trial
[Effects of the injection method of lidocaine on preventing injection pain during anesthesia induction by target controlled infusion with propofol].
We conducted a prospective randomized study to assess the effects of preceding lidocaine on the incidence and intensity of propofol-induced pain. ⋯ We conclude that pre-administration of lidocaine without infusion and restart infusion before propofol injecting into a dorsal hand vein is clinically useful.
