“…An interesting randomized controlled trial also compared the use of 1% lidocaine with 1:100,000 epinephrine to 0.5% lidocaine with 1:200,000 epinephrine in several body locations and showed equivalent patient comfort, injected volumes, and surgery onset although the lower concentration used half of the total lidocaine dose. 16 Although this study population only involved 5 cases on the hands, feet, and genitalia, and only one of these patients was infiltrated with 0.5% lidocaine, this is the only study in addition to ours that documents the use of this anesthetic concentration during Mohs micrographic surgery. An interesting follow-up study would be to investigate hemostasis and pain control through a randomized controlled trial involving the digits alone, comparing the use of 1% lidocaine with 1:100,000 epinephrine to 0.5% lidocaine with 1:200,000 epinephrine.…”
