Brief summary

To compare several local anesthetics when used during dermatological surgery.

Detailed description

This study is a randomized, controlled trial comparing the effectiveness of several local anesthetics, including lidocaine, mepivacaine, bupivacaine, and chlorprocaine when used for Mohs Microscopic Surgery (MMS) to see which is the most effective.

Design outcomes

Primary

MeasureTime frameDescription
Determine if pain increases with local injections at each stage of surgery.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.

Secondary

MeasureTime frameDescription
Pain control using mepivacaine as a primary anesthetic agent5 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, 45 minutes (reconstruction)Determine if using mepivacaine as the primary anesthetic will lower the patient verbally reported pain scores. 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.
Pain control using bupivacaine with epinephrine as a primary anesthetic agent5 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, 45 minutes (reconstruction)Determine change in patients verbally reported pain scale when using bupivacaine with epinephrine as the primary anesthetic. 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.
Pain control using bupivacaine as a primary anesthetic agent5 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, 45 minutes (reconstruction)Determine change in patients verbally reported pain scale when using bupivacaine as the primary anesthetic. 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.
Ideal anesthetic agents for varying sizes of tumors5 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.
Ideal anesthetic agents for varying anatomic location of tumors5 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, 45 minutes (reconstruction)Determine which anesthetic works best for tumors in different locations of the body. 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.
Overall tolerability of MMS5 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, 45 minutes (reconstruction)Assess patients ability to tolerate the surgery with different anesthetics. 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.
General length of time required for various steps of MMS5 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, 45 minutes (reconstruction)Assess the length of time it took to move from one stage to the next.
