Pain : Topical Anesthetics
The following article concludes: "LAT gel (4% lidocaine, 1:2000 adrenaline,
0.5% tetracaine) worked as well as TAC gel (0.5% tetracaine, 1:2000 adrenaline,
11.8% cocaine) for topical anesthesia in facial and scalp lacerations. Considering
the advantages of a noncontrolled substance and less expense, LAT gel appears
to be better suited than TAC gel for topical anesthesia in laceration repair
in children."

The following article reported that a triple-anesthetic gel containing benzocaine,
lidocaine, and tetracaine ("BLT") applied prior to treatment with
a 532-nm KTP laser resulted in significantly lower pain scores than with 3
other topical anesthetics at 15, 30, 45, and 60 minutes after application.
