a) Topical anaesthetic
It reduces the slight discomfort which is associated with the insertion of the needle and is effective to a depth of 2mm. It is beneficial for decreasing the patient's discomfort during the initial phase of surgery.
b) Local anaesthetic
It is an anaesthetic drug which can be given either by spray, shot or ointment on a small patch area on the body. It sedates an area of a person for a short period of time during surgery and controls post-surgery discomfort as well.
