Local Anesthetics for Mohs Surgery

This trial tests different local anesthetics to evaluate their effectiveness during Mohs surgery, a procedure for removing skin tumors. Researchers compare several anesthetics, including bupivacaine, chlorprocaine, lidocaine, and mepivacaine, to identify the best option for patients. Individuals with a skin tumor requiring Mohs surgery might be suitable candidates for this trial. As a Phase 4 trial, the anesthetics have already received FDA approval and proven effective, and this research aims to understand how they benefit more patients.

The trial information does not specify whether you need to stop taking your current medications.

Research has shown that the local anesthetics bupivacaine, chlorprocaine, and mepivacaine are generally safe and well-tolerated in medical settings, such as surgeries.

Bupivacaine is considered very safe for skin surgeries, with minimal side effects. For example, only 1.5% of patients experienced nausea, which is quite low. However, like lidocaine, bupivacaine can rarely cause heart-related issues if used in high doses.

Chlorprocaine is also effective in surgeries, achieving a 93.8% success rate in a large study, indicating it works well with few problems in most cases.

Mepivacaine, often used in dental and skin procedures, is both safe and effective. Studies comparing it to lidocaine, another common anesthetic, show similar safety levels.

Researchers are excited about these local anesthetics for Mohs surgery because they offer a variety of options tailored to patient needs, potentially improving the surgical experience. Unlike the standard lidocaine, options like bupivacaine and mepivacaine hydrochloride provide longer-lasting numbness, which can be beneficial for lengthy procedures. Chlorprocaine may offer a faster onset of action, which can be advantageous in reducing pre-surgical waiting times. These features allow for more flexibility and customization in managing pain during and after surgery.

This trial will compare the effectiveness of different local anesthetics for Mohs surgery. Research has shown that bupivacaine, which one treatment group may receive, effectively keeps the area numb for a longer time, reducing the need for pain medication afterward. It also reduces post-surgery pain, leading to less opioid use. Participants in the same group may also receive mepivacaine or chlorprocaine, which numb the area during surgery. However, less research exists on their specific effectiveness for Mohs surgery compared to bupivacaine. Overall, these numbing medicines are well-tolerated and help make the surgery experience smoother with less pain.⁵⁶⁷⁸⁹
