The anesthesia that Drs. Azouz, usually used to cut tendons of the hands and fingers, is a combination of axillary block, local anesthetic, and sedative medication. The axillary block continues to give the patient pain relief for 8-24 hours after initial injection.
The sedation anesthetic is used to help relax the patient while they continue to breath on their own. Many patients do fall asleep during their procedure.
