Randomized Controlled Trial
Topical ethyl chloride to reduce pain associated with venous catheterization: a randomized crossover trial.
To compare pain associated with venous catheterization after administration of topical ethyl chloride vs placebo among emergency department health care providers. ⋯ We found that topical ethyl chloride yields a greater reduction in pain associated with venous catheterization compared with topical placebo.

Randomized Controlled Trial
Prospective, randomized, double-blind controlled trial comparing vapocoolant spray vs placebo spray in adults undergoing venipuncture.
Topical anesthetics are used to decrease procedural pain such as venipuncture. Advantages of vapocoolants include rapid onset, ease of application, low cost, and lack of associated pain of injection and other needlestick-related risks. We hypothesized that the pain of venipuncture would be reduced by at least 1.8 points on a 10-point numerical rating scale after application of a vapocoolant compared with placebo. ⋯ The vapocoolant significantly decreased venipuncture pain in adults compared with placebo and was well tolerated with minor adverse effects that resolved quickly. There were no significant differences in VS and no visible skin changes documented at the site by photographs taken within 5 to 10 minutes postspray/venipuncture.
