Overview
Brief Summary
The purpose of this study is to compare how well different anesthetic, or numbing, solutions injected under the skin work in reducing the discomfort associated with placing a catheter in a vein. Two different medications, lidocaine and normal saline with benzyl alcohol, have been found to be effective in reducing discomfort when injected under the skin just prior to inserting the catheter. This study compares these two solutions, and will compare the discomfort that occurs both with and without using these solutions.

Differences in Patients' Perceptions of Pain Between Treatment Methods
Time Frame: at pre injection, during anesthetic injection, and during catheter insertion, up to approximately 1 minute
The visual analog pain scale is a patient-reported measure of pain on a 10-point scale with 0 being no pain and 10 being worst possible pain. The visual analog pain score will be completed at the following time points: pre injection, during injection, and during catheter insertion.
