Primary Outcome Measures:
  • Pain Score on the Numeric Rating Scale (NRS) [ Time Frame: pain of intravenous catheter placement. ] [ Designated as safety issue: No ]
    Numeric rating scale (NRS) 0-10 : 0 (no pain) - 5 (moderate pain) - 10 (worst pain). Scores to be utilized after stream device applied and after intravenous catheter placement.

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.

Ages Eligible for Study:   18 Years to 80 Years   (Adult, Senior)
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients needing intravenous cannulation
  • Adults age 18 years equal or greater than.
  • Stable patient

Exclusion Criteria:

  • Patients with any allergies to the spray components ( e.g.1,1,3,3, pentafluoropropane or 1,1,1,2 tetrafluoroethane )
  • Critically ill or unstable patient (e.g. sepsis or shock)
  • Infants and children of age , <18 years.
  • Pregnant
  • Intravenous cannulation site located in area of compromised blood supply. (ex: patients with Peripheral Vascular Disease , Raynaud's disease, gangrene, Buerger's disease)
  • Intravenous cannulation site located in area of insensitive skin; such as , patients with a peripheral neuropathy including diabetic neuropathy.
  • Patient intolerant of cold or with hypersensitivity to the cold.
  • Patient unable or unwilling to give consent.
