Numbing cream
The numbing cream must be applied one hour before your child's appointment.
Please buy the numbing cream from any pharmacy if your consultant has not prescribed it for your child.
Applying the cream
You will need:
- the numbing cream- 'Lidocaine + Prilocaine' or 'Ametop'
- four strips of cling film.
Do not rub the cream in, as this means it will not work. Do not worry about spreading the cream, as when the cling film is applied, the pressure will do this.
The cream needs to be applied to all four areas as below, which should then be wrapped with cling film to secure the cream.
Please do not use sticky patches, as they can hurt when removed, and the cream does not spread as well.
The backs of both hands:
The inside of both elbows:
When finished your child should look like this:
Please do not use sticky patches as they can hurt when removed and the cream does not spread as well.
If your child has a reaction to the cream, e.g. itching, please remove the cream from that area and wash with soap and water.
If your child is very young, and you are worried that they may pull the cling film off, please put a long-sleeved top on them and gloves or socks on their hands to try to stop them from doing so.
The Phlebotomist will remove the cling film and any cream that is left on.
Feel free to bring in any comfort object such as a teddy, blanket or dummy. Some distraction activities like 'Where's Wally' are available, but please bring your own tablet / toy / book as appropriate.
Perhaps watch CBeebies on iPlayer or a Dr Ranj video if you think it will help your child.
