Injecting 30 cc of 2% lidocaine challenged

In “Cone biopsy: perfecting the procedure” [January], Marc Toglia, MD, stated that he injects between 20 and 30 cc of 2% lidocaine with epinephrine in a concentration of 1:200,000 paracervically. The maximum recommended dosage of this premixed solution is 500 mg or 25 cc. Using 30 cc, or 600 mg, of lidocaine is potentially lethal.
