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
