About this study

Official title: The Effect of Lidocaine Injection at Different Concentrations on Postoperative Pain in Patients Using Head Holder.

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.

Read the detailed description

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.

Being tested
lidocaine was administered subcutaneously at 0.5% concentration., lidocaine was administered subcutaneously at 1% concentration.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The aim of this study is to compare postoperative pain levels between two groups of neurosurgery patients who underwent surgery using a head holder.

    The aim is to alter pain levels of these two operated groups at the first, third, sixth, twelfth, and twenty-fourth hours after surgery. Change from baseline in pain Scores on the Visiual Analog Scale at one day after surgery

    Measured: 5 years
