Purpose:
To determine whether prilocaine is a more comfortable local infiltration anaesthetic agent than the more widely used lignocaine for minor eyelid procedures.
Methods:
A prospective randomised study was undertaken to compare the discomfort between local infiltration of plain 2% prilocaine versus its equivalent, plain 2% lignocaine. One hundred and twenty-five patients were recruited. Pain was assessed subjectively using a visual analogue pain score, graded from 0 to 10.
Results:
The mean pain score for the prilocaine group was 1.82 compared with 3.19 for the lignocaine group. Using the Mann-Whitney U-test for significance, U = 1236.5; p < 0.001.
Conclusion:
Prilocaine is a more comfortable local infiltration anaesthetic agent than lignocaine when used for minor eyelid procedures.

Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...
