The investigators propose to examine if Pain Ease spray, used as an adjunct to the topical anesthetic Ametop Gel, can improve the percentage of pain-free IV starts.
Purpose:
The aim of this study is to assess the effectiveness of Pain Ease® spray, used as an adjunct to Ametop Gel™.
Hypothesis:
The investigators hypothesize that using Pain Ease® spray as an adjunct to the standard use of Ametop Gel™ will increase the number of pain free venipunctures from 30% to 50% or more.
Objectives:
Primary Objective
Research Design:
The investigators propose a patient-blinded randomized control trial of Ametop Gel™ with and without Pain Ease® spray as an adjunct.
Statistical Analysis:
An interim analysis will be performed at the study's halfway point after recruitment of 120 participants. A score on the Faces Pain Scale - Revised (FPS-R) of either 0 or 2 will be considered a pain-free IV start, while a score of 4-10 will be considered a painful IV cannula insertion. Fischer's Exact test will be used to determine statistical significance; a critical alpha of 0.05 will be considered for significance.
