Hypothesis: Lidocaine-Prilocaine Combination is as effective as Vapocoolant in treating IV cannulation pain in the emergency department.
Lidocain-Prilocaine combination cream is two amide-type local anesthetics used for topical skin anesthesia. Vapocoolant spray is also another method for providing appropriate analgesia through crayoanesthetic mechanisms. Although there are some contraindications and adverse effects, these are widely used in the Emergency Department (ED) for IV cannulation pain.

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.
Time frame: immediately after the procedure.
Application 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.
Time frame: immediately after the procedure.
Catheterization attempts
Number of times the direction of IV catheter is changed before the successful cannulation. Exit from the skin is also considered an attempt.
Time frame: immediately after the procedure.
