The nurse is preparing to administer a topical anesthetic to a 10-year-old girl with a chin laceration. The nurse would expect to apply which of the following as ordered in preparation for sutures?
A) TAC (tetracaine, epinephrine, cocaine)
B) Iontophoretic lidocaine
C) EMLA
D) Vapocoolant spray
A
Response:
TAC (tetracaine, epinephrine, cocaine) is commonly used for lacerations that require suturing. The agent can be applied directly to the wound with a cotton ball or swab for 20 to 30 minutes until the area is numb. EMLA and iontophoretic lidocaine are applied to intact skin, not to open wounds or lacerations. A vapocoolant spray, which should not be applied over a wound, is effective for only 1 to 2 minutes.
