Interesting! MedlinePlus: Spray dulls the pain of needles in kids: study

NEW YORK (Reuters Health) - A cooling spray reduced pain by 34 percent in children having intravenous procedures, such as injections and tube insertions, compared with a placebo group, researchers report. As well, successful insertion of a needle or tube was more frequent after using the spray.
"The spray is non-toxic, less expensive than alternatives, works immediately, and does not require a needle," Dr. William M. Splinter, of the Children's Hospital of Eastern Ontario, Ottawa, Canada, said in a written statement. "Effective pain relief decreases anxiety levels in children and parents," he added.
Splinter and colleagues tested the efficacy of the "Pain Ease" spray versus placebo in 80 children between the ages of 6 and 12 years who required urgent intravenous procedures.
Results showed that use of the cooling spray significantly reduced pain compared with placebo.
Fifty percent of the children treated with the spray reported having no pain or minimal pain, compared with 32 percent of those who received placebo.
Use of the spray was associated with successful tube insertion on the first attempt 85 percent of the time, compared with 62 percent with placebo.
"We determined that a topical anesthetic spray can reduce pain by 34 percent in children who need intravenous (tube insertion)," Splinter commented to Reuters Health. "The spray was quick and effective, without delaying the procedure, which was found to be of real benefit in an emergency department setting."

Anyone use this, or something similar? I know I've used EMLA before.
