The anesthetic method has the potential to allow physicians to keep injuries from evolving into neuropathic pain, a chronic form of pain that arises from flawed signals transmitted to damaged nerves.

The team combined saxitoxin, a powerful local anesthetic, with dexamethasone to prolong saxitoxin’s effects. The two ingredients contain liposomes for nontoxic delivery to the site of nerve or tissue damage.
