The Use of Micro Vibratory Stimulation Technique to Control the Pain of Digit Block Anesthesia

The Use of Micro Vibratory Stimulation Technique to Control the Pain of Digit Block Anesthesia

The investigators hypothesize that patients who receive 1% lidocaine injections for digit blocks of the finger will experience less pain when the injection is accompanied by the use of a micro-vibratory stimulator (MVS) compared with patients who receive injections without the MVS.

Research Question/Hypothesis

The investigators hypothesize that patients who receive 1% lidocaine injections for digit blocks of the finger will experience less pain when the injection is accompanied by the use of a micro-vibratory stimulator (MVS) compared with patients who receive injections without the MVS.

Objectives

The primary objective of this study is to compare the pain rating scale from an exposure group (digit block injection with the aid MVS) and the control group (traditional injection).

Inclusion Criteria:

• Healthy individuals between the ages of 18 and 65 who are willing and able to consent and who require the use of local anesthetic digit block to both sides of a finger for the treatment of wounds, injuries, infections, or laceration of the fingers.

Exclusion Criteria:

• Allergy to any type of local anesthetic.
• Inability to Consent.
• Inability to complete a numeric pain scale.
• Clinical appearance or clinical evidence of intoxication.
• Significant compromising conditions such as major trauma and severe respiratory distress.
