Aim:The head holder used in neurosurgery operations causes pain in patients both peroperatively and postoperatively.Severe pain-related hemodynamic changes are seen in these participants.In our study, the investigators compared the effects of two different concentrations of lidocaine on the perioperative and postoperative hemodynamic response caused by the application of the head-holder, and the pain observed in the postoperative period.

Method: Ethics committee approval and participants consent were obtained. Lidocaine 0.5% in Group 1 and 1% lidocaine in Group 2 was administered subcutaneously, 3 ml to each three points, in a total of 9 ml. Postoperative analgesic efficacy and tramadol consumption amounts of different concentrations of lidocaine were compared in participants who used a head holder.

1% concentration of lidocaine as skin infiltration before wearing a head-holder.

compared to 0.5% concentration lidocaine application, pain was controlled in the first hour of the postoperative period.
