Randomized Controlled Trial Clinical TrialBenzyl alcohol attenuates the pain of lidocaine injections and prolongs anesthesia.
Benzyl alcohol is reported to be painless on injection and to provide limited dermal anesthesia. Benzyl alcohol has also been recommended as an adjuvant to lidocaine to reduce lidocaine's injection pain. There is insufficient data on pain of injection and duration of anesthesia for lidocaine containing benzyl alcohol. ⋯ Benzyl alcohol is itself an effective anesthetic and can reduce the pain of injection for lidocaine without adversely affecting its anesthetic properties.

Randomized Controlled Trial Clinical TrialPain of injection and duration of anesthesia for intradermal infiltration of lidocaine, bupivacaine, and etidocaine.
Bupivacaine and etidocaine are local anesthetics said to be long acting based on nerve block data. There are insufficient data on pain of infiltration and duration of anesthesia when either is used for dermal infiltration to assess suitability for skin surgery. ⋯ Where epinephrine is contraindicated and long anesthesia matters, use plain bupivacaine. When epinephrine can be used, lidocaine lasts almost as long as bupivacaine and hurts less.

Randomized Controlled Trial Clinical TrialA double-blind placebo controlled study of a 5% lidocaine/prilocaine cream (EMLA) for topical anesthesia during thermolysis.
Electrolysis and thermolysis are commonly used electrosurgical methods for the permanent destruction of unwanted hair. However, patient fear of pain during treatment may interfere with or even prevent desired treatment of hirsutism on sensitive areas such as the upper lip. ⋯ EMLA cream may have multiple applications to the practice of dermatologic surgery, including topically achieved local anesthesia during thermolysis and electrolysis.
