Primary Outcome Measures:
  • Pain score on the visual analog scale [ Time Frame: <1 minute after stream device application, , 1 minute after intravenous catheter placement. ] [ Designated as safety issue: No ]
    Numeric rating scale (VAS) 0-10 : 0 (no pain) - 5 (moderate pain) - 10 (worst pain). Scores to be utilized after stream device applied and after intravenous catheter placement.

Secondary Outcome Measures:
  • Patient satisfaction with the procedure [ Time Frame: Within one hour of intravenous cannulation. ] [ Designated as safety issue: No ]
    Patient self reported satisfaction with the procedure using an eight item questionnaire developed specifically for the study.

  • Health Care Provider satisfaction with the procedure [ Time Frame: Within one hour of intravenous cannulation. ] [ Designated as safety issue: No ]
    Health Care provider self reported satisfaction with the procedure using a six item questionnaire developed specifically for the study

  • Ease of insertion of intravenous catheter placement [ Time Frame: Duration of time to establish an IV catheter in the Emergency Department ] [ Designated as safety issue: No ]
    Questionnaire: Success in one attempt; number of attempts ; location of intravenous catheter placement;Health care provider inserting IV catheter ( Registered Nurse, paramedic, Emergency Medical Technician, Nurse Practitioner /Physician Assistant , Medical Doctor ); years of experience of performing IV's

  • Number of participants with adverse events. [ Time Frame: Within 1 hour after application of the device ] [ Designated as safety issue: Yes ]
    Utilized as a measure of safety and tolerability.Skin assessment at site of post stream device application /Clinical assessment : description of skin at site: redness, blanching, change in skin color pigmentation. Photograph of site to confirm clinical description.

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
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
  • Mentally competent patient able to understand the consent form

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.
