Outcome Measures

Primary Outcomes (1)

  • Cannulation pain: numerical rating score (NRS)

    The numerical rating score (NRS) will be used for the study. The NRS ranges from 0 (no pain) to 10 (very severe pain). The higher the pain scores the higher the pain severity. The pain severity will be asked from the patients.

    immediately after the procedure.

Secondary Outcomes (2)

  • Application pain: numerical rating score (NRS)

    immediately after the procedure.

  • Catheterization attempts

    immediately after the procedure.

Study Arms (2)

Vapocoolant spray

ACTIVE COMPARATOR

Patients in this arm will receive vapocoolant spray before IV cannulation.

Drug: Vapocoolant spray

Lidocaine-Prilocaine cream

ACTIVE COMPARATOR

Patients in this arm will receive Lidocaine-Prilocaine cream before IV cannulation.

Drug: Lidocaine-Prilocaine cream

Interventions

The spray will be applied continuously from 25 cm distance for less than 5 seconds to the cannulation site.

Vapocoolant spray

A finger tip (0.5 gr) of the cream will be applied in 4 square cm at cannulation site and will be covered with closed dressing for 45 minutes.

Lidocaine-Prilocaine cream
