The aim of this study is to investigate sterility of ethyl-chloride topical anesthetic spray when used prior to an injection. The hypothesis is that the spray does not change the sterility of the injection site after skin is prepped.

Skin Sterility After Use of Ethyl-chloride Spray.

Primary Outcome Measures:
  • culture positivity [ Time Frame: 5 days ]
    Cultures before and after Ethyl-Chloride spray are compared to see if there is any difference.

Secondary Outcome Measures:
  • Native skin flora [ Time Frame: 5days ]
    Cultures of skin prior to skin prep are taken to define to native flora at the shoulder and knee area.

Enrollment: 15

Healthy Volunteers
15 healthy volunteers were recruited

Detailed Description:
This is an IRB-approved, prospective, blinded, controlled study. In the first set of experiments, skin sterility is assessed. Healthy adult subjects are prepared for mock injections of shoulders and knees. No injection is performed. Each site has a set of 3 skin cultures: 1) prior to the alcohol prep (pre-prep), 2) post-alcohol prep (pre-spray), and 3) after ethyl-chloride was sprayed on the site (post-spray). In the second set of experiments, sterility of ethyl chloride is tested directly by culturing the liquid from the spray bottles.
