Local anaethetics produce loss of sensation where the are applied to the body ie lidocaine.

Local anaethesia describes any way in which they are used ie by injection when you visit the dentist or an epidural when you have a baby.

Topical anaethesia refers to the use of local anaethetics when they are simply put on the skin ie EMLA cream. Used most commonly for pain free blood sampling in children.
