- Redirect needle toward palmer nerve and inject.
- Repeat for opposite side of digit.

What is infiltration anesthesia?
Infiltration anesthesia is accomplished with administration of the local anesthetic solution intradermally (ID), subcutaneously (SC), or submucosally across the nerve path that supplies the area of the body that requires anesthesia.Are you put to sleep for trigger finger surgery?
