Local anesthesia using buffered 0.5% lidocaine with 1:200,000 epinephrine for tumors of the digits treated with Mohs micrographic surgery.
Several specialties and textbooks continue to advocate that local anesthesia using epinephrine should not be used during surgery involving the digits. ⋯ There is no evidence that buffered 0.5% lidocaine with epinephrine 1:200,000 causes ischemia or necrosis when injected into digits. This is true despite a history of circulatory disorders, thrombosis, diabetes, smoking, anticoagulation, or significant preoperative hypertension.
