The aim of this study is to determine if local application of heat increases the probability of insertion of peripheral venous catheter at the first attempt, reduces the time needed to obtain cannulation and maintains the analgesic effect of Emla in children undergoing peripheral venous cannulation and previously treated with local analgesia with Emla.

rate of success of peripheral venous cannulation at the first attempt
Time frame: The outcome is observed and recorded immediatly after the venous cannulation. No follow up is required
pain perceived by the child undergone to the cannulation
The pain level is estimated using a visual analog scale (from 0 to 10) or the Wong "faces'" Scale
Time frame: The outcome is observed and recorded immediatly after the venous cannulation. No follow up is required
Difficulty in performing cannulation perceived by Nurse
This outcome is calculated using an "ad hoc" Visual Analog Scale (from 0 to 10)
Time frame: The outcome is observed and recorded immediatly after the venous cannulation. No follow up is required
Time needed to obtain cannulation
Time is calculated in seconds
Time frame: From positioning tourniquet to completion of cannulation. No follow up is required
