Study Summary
This trial is comparing two different techniques for digital blocks, the traditional dorsal technique and the volar technique. The study will follow a two-period cross-over design with four groups that are defined by the sequence of treatments within each group.
Who is the study for?
This trial is for physicians over 18 who regularly perform digital blocks, including specialists in Orthopaedic Surgery, Pediatrics, Family Medicine, and Emergency Medicine. It's not suitable for those pregnant, with blood diseases, past bad reactions to lidocaine, missing an index finger on either hand or with neuropathy or peripheral vascular disease.Check my eligibility
What is being tested?
The study compares two techniques of numbing fingers (digital blocks) using injections: the traditional dorsal (back of the hand) approach versus a volar (palm side) approach. Participants will try both methods using lidocaine and saline in a randomized double-blinded cross-over design.See study design
What are the potential side effects?
Possible side effects include pain at the injection site and potential allergic reactions to lidocaine for those not previously identified as having an allergy. Since saline is harmless when injected correctly, no side effects are expected from it.
