Minimal Pain Tumescent Local Anesthesia Injection for Wide Awake Modified Radical Mastectomy.

The advent of minimal pain tumescent local anesthesia injection has improved patient safety by eliminating the need for sedation for many wide awake operations, especially in patients with significant medical comorbidities. Modified radical mastectomy (MRM) for breast cancer is commonly performed under general anesthesia as it requires the dissection of the entire breast and an ipsilateral axillary lymph node dissection (ALND). General anesthesia has been shown to have a high risk in patients with severe medical comorbidities.
