The Effect of Intravenous Lidocaine on Allodynia

The Effect of Intravenous Lidocaine on Allodynia (Carl Koller Grant)

The purpose of this study is to study if lidocaine, given intravenously, reduces pain.

Study Overview

• Status: Completed
• Conditions: Pain
• Intervention / Treatment: Drug: lidocaine

Detailed Description

Clinicians use lidocaine intravenously in a fashion that suggests that it might have analgesic effects. Therefore, we test the hypothesis that lidocaine reduces pain intensity in response to experimental pain.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pain Perception	Assessing heat pain perception (pain intensity) before, during, and after lidocaine infusion by means of patient self-report using a mechanical slide algometer. The mechanical slide algometer [Price et al. (1994)] looks like a ruler that exposes a red bar with the end-points: no pain (left) and most pain imaginable (right). The use the slider to express their perceived pain. On the back of the ruler a numerical scale ranging from 0 (no pain) to 10 (worst imaginable pain) translates the patient's rating into a numeric scale.	Participants will be followed from baseline through 128 minutes
