An Evaluation of the Effectiveness of Local Anesthetics Used During Intravenous Catheter Insertion

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02162680

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.

Arm Intervention/treatment
Active Comparator: lidocaine
1% lidocaine intradermal injection
Drug: 1% lidocaine
Active Comparator: bacteriostatic normal saline (BNS)
bacteriostatic normal saline (BNS) injection
Drug: bacteriostatic normal saline (BNS)
No Intervention: no local anesthetic
usual care practice of no local anesthetic administration

Primary Outcome Measures :
  1. 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.
