Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The volunteer will be cannulated with 2 x 20G intravenous catheters, one after another. Once following anaesthesia with Coolsense® device and then again with anaesthesia from EMLA cream which will have been applied 45 minutes previously.

The Coolsense device is applied to the skin (at the site of cannula insertion) for 10 seconds to cool and numb the skin. The vein is cannulated immediately after the device is removed from the skin. The coolsense device is administered by the person performing the cannulation. The data collector (investigator) will ensure the coolsense device is used in accordance with the manufacturer's instructions.

The same volunteer will also be cannulated on the other hand which has had application of EMLA cream to numb the skin. In this way, the participant acts as their own control. Details of the EMLA treatment are given below.

Comparator / control treatment
Cannulation with 20G IV catheter following topical anaesthesia with EMLA®. EMLA is a cream containing 2.5% lignocaine and 2.5% prilocaine (local anaesthetic agents) which is applied to the skin over the site for cannulation. The cream is generously applied over the site of cannulation and covered with a clear plastic dressing at least 45 minutes prior to the cannulation attempt. The data collector (investigator) will ensure the EMLA is applied correctly.

Summary
Brief summary
Almost all patients presenting for anaesthesia will require an intravenous cannula prior to surgery. However, many patients find this an unpleasant experience and this leads to a great deal of anxiety and in some cases needlephobia.

With the CDHB, the Coolsense® device has recently been introduced to cool and anaesthetise the skin prior to cannulation. However, there are no studies published in peer review journals comparing Coolsense® to topical anaesthetic cream, eg EMLA®.

We hypothesis that Coolsense® will provide an equivalent level of satisfaction to EMLA®.

We will ask healthy volunteers (adults over 18 years) to agree for two 20G intravenous cannulas to be inserted into each hand. Prior to insertion, one hand will be anaesthetised with the application of EMLA®, a topical local anaesthetic cream which will be applied a minimum of 45 minutes prior to cannulation and the other hand using Coolsense® according to the manufacturer’s instructions. Groups will be randomised to determine which hand is anaesthetised with Coolsense®, which hand anaesthetised with EMLA® and which hand will be first to cannulated.

The volunteers will be asked to record pain on a numerical pain rating scale of zero to ten and rate their satisfaction (scale zero to to 10) for each method of topical anaesthesia. They will then be asked to state which technique was preferred (options: EMLA, Coolsense, both similar).
