Brief summary

To determine the efficacy and safety of vapocoolant stream (Pain Ease Medium Stream ) in decreasing the pain of intravenous cannulation. To compare vapocoolant stream (Pain Ease medium Stream) with control (e.g. sterile water) stream.

Detailed description

Vapocoolant sprays have been used to decrease the pain associated with painful medical procedures such as immunizations, needle aspirations, injections, venipuncture and intravenous cannulation. In general, vapocoolant sprays , have been found to be effective in decreasing the pain of various medical procedures. Moreover, the use of vapocoolant sprays ,unlike other local anesthetics , such as infiltrative lidocaine , is not associated with a painful injection and does affect the success rate of the procedure including intravenous cannulation and may even increase the success rate of the intravenous cannulation.

Interventions

Topical stream of 4 to 10 seconds duration to skin

DEVICESterile water

Topical intervention of sterile water stream 4 to 10 seconds to skin.
