Lidocaine IV Infusion in Two Doses for Neuropathic Pain Post-Mastectomy

This study focuses on managing neuropathic pain, a type of pain often experienced by patients who have undergone mastectomy for breast cancer. The pain can be challenging to manage, with various drugs like opioids and antidepressants used, but these come with side effects. The study aims to find a safer and more effective solution by comparing two different doses of Lidocaine, an amide local anesthetic. Lidocaine has been found to provide pain relief in several chronic neuropathic conditions with fewer side effects. It's also known to have an opioid-sparing effect, meaning it can reduce the need for opioids. The study hopes to improve care for patients experiencing neuropathic pain after mastectomy. During the study, participants will receive Lidocaine through an IV injection. The study's primary goal is to assess the neuropathic pain scale, a tool designed to measure the distinct qualities and intensity of nerve-related pain. This scale helps distinguish neuropathic pain from other types of pain. It evaluates 10 specific qualities associated with neuropathic pain, such as burning, freezing, and stinging, using a 0-10 numerical rating for each. The study aims to understand how effectively Lidocaine manages these symptoms and improves the overall quality of life for patients.
