Which item is commonly used to numb the area during a sebaceous cyst incision and drainage?

• A. Gauze
• B. Lidocaine
• C. Fenestrated drape
• D. Packing

Answer: (B)

Numbing the area with a local anesthetic before minor skin procedures helps patients tolerate the incision and drainage and allows the clinician to work precisely. Lidocaine is the standard local anesthetic used for this purpose because it rapidly blocks nerve signaling by inhibiting sodium channels in nerve membranes, creating a numb field around the cyst. It’s injected around the area to provide targeted pain relief within minutes, and its effects last long enough to complete the procedure, with the option to add epinephrine to prolong anesthesia and reduce bleeding in many cases. Gauze is for absorbing blood and keeping the area clean, not for numbing tissue. A fenestrated drape is used to maintain a sterile field during the procedure, and packing is used to fill the wound or wick drainage after the cyst is drained. These items support the procedure and wound management, but they don’t provide anesthesia.
