Primære resultatmål

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
Determine if pain increases with local injections at each stage of surgery.
Tidsramme: 5 mins, 15 mins, 20 mins, 25 mins, 30 mins, 45 mins (reconstruction)
Assess changes in pain levels by determining if longer acting agents such as bupivacaine or bupivacaine with epinephrine will show lower reported pain scores by patients compared to shorter acting anesthetic agents such as lidocaine with epinephrine or mepivacaine when undergoing Mohs micrographic surgery. Patients will rate their pain verbally using the visual analog scale (VAS) of 1-10, where 1 is no pain and 10 is worst pain possible.
5 mins, 15 mins, 20 mins, 25 mins, 30 mins, 45 mins (reconstruction)

Ideal anesthetic agents for varying sizes of tumors
Tidsramme: 5 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, 45 minutes (reconstruction)
Determine which anesthetic works best for different size tumors. This will be measured using pain scores throughout the procedure prior to taking the stage as the patient will be numb after the stage is taken. The visual analog scale (VAS) of 1-10 will be used, where 1 means no pain and 10 is worst pain possible.
