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

Condition or disease Intervention/treatment Phase
Pain Drug: lidocaine Not Applicable

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.

Arm Intervention/treatment
Experimental: Lidocaine
Intravenous lidocaine for neuropathic pain
Drug: lidocaine
intravenous, effect site concentration: 2mcg/ml, 15-20 min infusion, once
Other Names:
  • Lidoderm
  • Xylocaine




Primary Outcome Measures :
  1. Pain Perception [ Time Frame: Participants will be followed from baseline through 128 minutes ]

    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.
