Summary

This is a prospective, randomized, double-blinded controlled trial comparing two different techniques for digital blocks. Participants will be physicians who perform digital blocks as part of their everyday duty. Each participant will undergo two digital blocks and will have the opportunity to perform a digital block on another participant.

This study follows a two-period cross-over design with four groups that are defined by the sequence of treatments within each group. Participants will receive two digital blocks, one using the traditional dorsal technique and one using the volar technique. Of the two injections, one of the syringes will contain 1% lidocaine without epinephrine and the other will contain sterile normal saline. The injections will be to the index finger on each hand. The hand injected first will be up to the participant. The order in which the dorsal technique versus the volar technique is performed will be randomized. Participants will not be told one of the syringes contains normal saline. Injection pain will be measured by visual analog score and recorded after each injection. Sensation in each of the 12 zones of the finger will be recorded at each minute mark until loss of sensation in all 12 zones is achieved or 15 minutes has passed, whichever comes first.
