Needlestick InjuriesNCT02086292
The Influence of Lidocaine Volume on Discomfort During Administration of Local Anesthetic
A study testing 2 ml 1% Lidocaine and 1 ml 2% Lidocaine in people with Needlestick Injuries, run by Norwegian University of Science and Technology at 1 site in Norway.
Trial summary
The aim of the study is to find a simple method for pain reduction that can be used in clinical practice when administering digital nerve block with a single subcutaneous injection. It will be investigated whether a smaller volume of lidocaine can decrease pain during injection. Read more about this study

About this study
The aim of the study is to find a simple method for pain reduction that can be used in clinical practice when administering digital nerve block with a single subcutaneous injection. It will be investigated whether a smaller volume of lidocaine can decrease pain during injection.
Read the detailed description
Healthy volunteers will receive a single subcutaneous injection digital nerve block at the base of each ring finger. 2ml 1% lidocaine in one of the fingers, and 1 ml 2% lidocaine in the other. After each injection, the subject will be asked to evaluate the pain on a visual analog scale (0-100 mm). Additionally the sensibility will be tested with a Semmes-Weinstein monofilament, to evaluate if the different methods achieve desired anesthetic effect.

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02086292, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
