Question 35 of 35

Yes. That is correct.

Applying topical anesthetic at an injection site for 4 minutes can cause sloughing of the epithelium. It is recommended that topical anesthetic contact the mucous membranes for only 1 - 2 minutes.

Other factors that may cause sloughing of tissues can be sensitivity of the tissues to the topical or a reaction to the topical anesthetic.

Remember that a vasoconstrictor is NOT found in topical anesthetic.
