Video Summary

Local anesthesia is crucial for dermatologic procedures, utilizing both topical and injectable methods, like lidocaine. For deeper numbing, injections intradermal (at 15-degree) and subcutaneous (at 45-degree) are used. Intradermal offers quick action but more discomfort, while subcutaneous is less painful. Injections often combine for optimal effect, with epinephrine included to prolong anesthesia and reduce bleeding. Alternatives like procaine suit lidocaine-allergic patients. Pain can be minimized with topical preparation, ice, vibration, slow injection, and buffering agents. Syringes are safely handled to prevent discomfort and ensure safety.
