Pain, Analgesia
Conditions
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).
Interventions
DEVICEMicrovibratory 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.
DEVICEMicrovibratory Stimulator'
As above, Microvibratory Stimulator will be used as a sham device in parallel group.
