Patient and Health Care Provider Responses from a Prospective, Double-Blind, Randomized Controlled Trial Comparing Vapocoolant Spray versus Placebo Spray in Adults Undergoing Venipuncture in the Emergency Department

Background: Painful medical procedures are common. Topical anesthetics are easily applied, rapid onset, inexpensive, and avoid injection pain and needlestick injury. The aims of this study, using patient and health care provider questionnaires, were to answer the following questions: (1) Does vapoco...

Description
Summary:Background: Painful medical procedures are common. Topical anesthetics are easily applied, rapid onset, inexpensive, and avoid injection pain and needlestick injury. The aims of this study, using patient and health care provider questionnaires, were to answer the following questions: (1) Does vapocoolant spray decrease venipuncture pain? (2) Would patients be satisfied with and use a vapocoolant spray in the future? (3) Would providers be satisfied with and use a vapocoolant spray in the future? Design: Adults (18-80 years) in a hospital emergency department (ED) were randomly assigned to sterile water placebo spray (S) (N = 50) or vapocoolant spray (V) (N = 50) before venipuncture. Questionnaires were completed by patients undergoing venipuncture (N = 100) and the health care providers (N = 100) who performed the venipuncture (total questionnaires = 200) as part of a prospective, double-blind, randomized controlled trial comparing the efficacy and safety of vapocoolant spray compared with placebo spray in patients undergoing venipuncture in the ED. Results: Patient and venipuncture variables were not significantly different for the two groups (S vs. V). Responses to the questionnaires were significantly different for the S versus V groups for both the patients and the health care providers. Patient questionnaires: Did you have less pain with spray?
