Will Adjusting the pH of Lidocaine Reduce the Pain During Injection of Local Anaesthetic?
A study testing Lidocaine injection with bicarbonate and lidocaine injection in people with Needlestick Injuries, run by Norwegian University of Science and Technology at 1 site in Norway.
Trial summary
This study will investigate the influence of adjusting the pH of lidocaine on pain during subcutaneous injection. Each participant will receive two injections on the abdomen with different pH. After each injection, the subject will be asked to evaluate the pain on a Visual analog scale (0-100 mm). Read more about this study

About this study
This study will investigate the influence of adjusting the pH of lidocaine on pain during subcutaneous injection. Each participant will receive two injections on the abdomen with different pH. After each injection, the subject will be asked to evaluate the pain on a Visual analog scale (0-100 mm). It is anticipated that the pain decreases with increasing pH. The aim of the study is to find a simple method for pain reduction that can be used in clinical practice.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Pain (time frame: 60 seconds). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02107716, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
