- Registration Number
- NCT02870595
- Lead Sponsor
- Christus Spohn Memorial Medical Center
- Brief Summary
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.
- Detailed Description
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).

Group Intervention Description Parallel lidocaine injection Microvibratory Stimulator' Informed consent will be obtained from patients undergoing finger local anesthesia digit blocks. Subjects will be randomly assigned (using GraphPAD Randomization Software Tool) to receive the first of their two digit block injections with either the traditional technique (control) or while using the DVICS/ Microvibratory Stimulator. All injections will utilize a 27-gauge needle. The subjects will be given a standard dose of 2mls of 1% lidocaine without epinephrine delivered over 30 seconds. Injections will be timed and performed by a single clinician to avoid large variations in technique and expertise. Parallel Microvibratory Stimulator In the sham comparator, the device will be placed on the skin, but not turned on. Digit block anesthesia will progress in usual fashion as with active comparator, except without the vibratory device engaged.
