Alkane vapocoolant sprays evaporate rapidly, lower skin temperature and result in a temporary interruption in pain sensation. They reduce the pain of intravenous cannulation. However, concern exists that they may recontaminate the sterile cannulation site. ⋯ Alkane vapocoolant spray does not recontaminate the skin after disinfection, and should pose no increased risk of infection when used as an anaesthetic agent prior to intravenous cannulation following disinfection. While it does have inherent bactericidal activity, this is not sufficient for it to be used as the sole disinfectant.
